<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>fim</b> is a
’swiss army knife’ for displaying image files.
It is capable of displaying image files using different
graphical devices while offering a uniform look and feel.
Key bindings are customizable and specified in an
initialization file. Interaction with standard input and
output is possible, especially in shell scripts. An internal
scripting language specialized for image viewing allows
image navigation, scaling, manipulation of internal
variables, command aliases, and Vim-like autocommands. The
internal language can be interacted with via a command line
mode capable of autocompletion and history (the readline
mode). Further features are display of EXIF tags, JPEG
comments, EXIF rotation/orientation, load of
"description files", faster load via image
caching, command recording, and much more.</p>
<p style="margin-left:11%; margin-top: 1em">As a default,
<b>fim</b> displays the specified file(s) on the detected,
most convenient graphical device. This can be with SDL if
running under X, an ASCII-art driver (aalib or libcaca) if
running behind ssh without X forwarding, or the linux
framebuffer device. Graphical file formats BMP, PCX are
supported natively, while JPEG, PNG, GIF, TIFF, PPM, PGM,
PBM, QOI, AVIF, WEBP are supported via third party
libraries. Further formats are supported via external
converters. For XCF (Gimp’s) images,
’xcftopnm’ or ’xcf2pnm’ is used. For
FIG vectorial images, ’fig2dev’ is used. For DIA
vectorial images, ’dia’ is used. For NEF raw
camera images, ’dcraw’ is used. For SVG
vectorial images, ’inkscape’ is used. For other
formats ImageMagick’s ’convert’ is used.
The converter is given 15 seconds for the conversion before
a timeout.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>{imagepath}</i> is a file, its format is guessed not by
its name but by its contents. See the <b>_file_loader</b>
variable to change this default.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>{imagepath}</i> is a directory, load files of supported
formats contained there. If <i>{imagepath}</i> contains a
trailing slash (/), it is treated as a directory; otherwise
that is checked via <b>stat(2)</b>. To change this default,
see description of the <b>_pushdir_re</b> variable and the
<b>--no-stat-push</b> and <b>--recursive</b> options.</p>
<p style="margin-left:11%; margin-top: 1em">This man page
describes <b>fim</b> command line options and usage. See man
<i>fimrc</i>(5) for a full specification of the <b>fim</b>
language, commands, keysyms, autocommands, variables,
aliases, examples for a configuration file and readline
usage samples.</p>
<h2>USAGE
<a name="USAGE"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">You may invoke
<b>fim</b> from an interactive shell and control it with the
keyboard, as you would do with any image viewer with
reasonable key bindings.</p>
<p style="margin-left:11%; margin-top: 1em"><b>fim</b> is
keyboard oriented: there are no user menus or buttons
available. If you need some feature or setting which is not
accessible from the default keyboard configuration, you
probably need a custom configuration or simply need to type
a custom command. For these, you can use the internal
command and configuration language.</p>
<p style="margin-left:11%; margin-top: 1em">See options
<b>--read-from-stdin</b>, <b>--script-from-stdin</b>, and
<b>--image-from-stdin</b> for more script-oriented
usages.</p>
<p style="margin-left:11%; margin-top: 1em">The full
commands specification is also accessible at runtime using
the internal help system (typing :help).</p>
<h2>OPTIONS
<a name="OPTIONS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Accepted
command line <i>{options}:</i></p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="11%"></td>
<td width="3%">
<p><b>--</b></p></td>
<td width="8%"></td>
<td width="78%">
<p>Treat arguments after <b>--</b> as filenames. Treat
arguments before <b>--</b> as command line options if these
begin with <b>-</b>, and as filenames otherwise.</p></td></tr>
</table>
<p style="margin-left:11%;"><b>-a</b>,
<b>--autozoom</b></p>
<p style="margin-left:22%;">Enable autozoom. Automagically
pick a reasonable zoom factor when displaying a new image
(as in <b>fbi</b>).</p>
<p style="margin-left:11%;"><b>-b[24|1]</b>,
<b>--binary[=24|1]</b></p>
<p style="margin-left:22%;">Display contents of binary
files (of any filetype) as these were raw 24 or 1 bits per
pixel pixelmaps. The width of this image will not exceed the
value of the <b>_preferred_rendering_width</b> variable.
Regard this as an easter bunny option.</p>
<p style="margin-left:11%;"><b>--as-text</b></p>
<p style="margin-left:22%;">Display contents of files (of
any filetype) as these were text. The width of this image
will not exceed the value of the
<b>_preferred_rendering_width</b> variable. Non-printable
characters are then displayed as " ". Regard this
as another easter bunny option.</p>
<p style="margin-left:11%;"><b>--cd-and-readdir</b></p>
<p style="margin-left:22%;">Step in the directory of the
first file to be loaded, push other files from that
directory, and jump back to the first file. Useful when
invoking from a desktop environment.</p>
<p style="margin-left:11%;"><b>-c</b> <i>{commands},</i>
<b>--execute-commands</b> <i>{commands}</i></p>
<p style="margin-left:22%;">Execute <i>{commands}</i> after
reading the initialization file, just before entering the
interactive mode. No semicolon (<b>;</b>) is required at the
end of <i>{commands}</i>. Do not forget quoting
<i>{commands}</i> in a manner suitable to your shell. So -c
next is fine as it is. A more complicated example, with
quotings: -c ’*2;2pan_up;display;while(1){align
"bottom";sleep "1" ; align
"top"}’ (with the single quotes) tells fim
to: double the displayed image size, pan twice up, display
the image, and finally do an endless loop consisting of
bottom and top aligning, alternated.</p>
<p style="margin-left:11%;"><b>-C</b> <i>{commands},</i>
<b>--execute-commands-early</b> <i>{commands}</i></p>
<p style="margin-left:22%;">Similar to the
<b>--execute-commands</b> option, but execute
<i>{commands}</i> earlier, just before reading the
initialization file. If <i>{commands}</i> takes the special
’early’ form <i>=var=val</i>, it assigns value
<i>val</i> to variable <i>var</i> immediately, before the
interpreter is started, and with no value quoting
needed.</p>
<p style="margin-left:22%; margin-top: 1em">For example, -C
’<b>_scale_style</b>=" "’ starts fim
no auto-scaling; the equivalent early form is: -C
’=<b>_scale_style</b>= ’.</p>
<p style="margin-left:11%;"><b>-d</b> <i>{fbdev},</i>
<b>--device</b> <i>{fbdev}</i></p>
<p style="margin-left:22%;">Framebuffer device to use.
Default is the one your vc is mapped to (as in fbi).</p>
<p style="margin-left:11%;"><b>--dump-reference-help[=man]</b></p>
<p style="margin-left:22%;">Dump to stdout language
reference help and quit.</p>
<p style="margin-left:11%;"><b>--dump-default-fimrc</b></p>
<p style="margin-left:22%;">Dump default configuration (the
one hardcoded in the fim executable) to standard output and
quit.</p>
<p style="margin-left:11%;"><b>-E</b> <i>{scriptfile},</i>
<b>--execute-script</b> <i>{scriptfile}</i></p>
<p style="margin-left:22%;">Execute <i>{scriptfile}</i>
after the default initialization file is read, and before
executing <b>--execute-commands</b> commands.</p>
<p style="margin-left:11%;"><b>-f</b> <i>{fimrc},</i>
<b>--etc-fimrc</b> <i>{fimrc}</i></p>
<p style="margin-left:22%;">Specify an alternative
system-wide initialization file (default:
/usr/local/etc/fimrc), to be read prior to any other
configuration file. See also <b>--no-etc-fimrc-file</b>.</p>
<p style="margin-left:11%;"><b>-F</b> <i>{commands},</i>
<b>--final-commands</b> <i>{commands}</i></p>
<p style="margin-left:22%;">Similar to the
<b>--execute-commands</b> option, but execute
<i>{commands}</i> after exiting the interactive mode, just
before terminating the program.</p>
<p style="margin-left:11%;"><b>-h[s|d|l|m]</b>,
<b>--help[=s|d|l|m]</b></p>
<p style="margin-left:22%;">Print program invocation help,
and exit. Depending on the option, output can be: short,
descriptive, long from man, or complete man. For each
further argument <i>{help-item}</i> passed to <b>fim</b>, an
individual help message is shown. If <i>{help-item}</i>
starts with a /, it is treated as a search string (not a
regexp, though).</p>
<p style="margin-left:11%;"><b>-k</b> <i>{keysym},</i>
<b>--keysym-press</b> <i>{keysym}</i></p>
<p style="margin-left:22%;">Execute any command bound (via
the bind command) to a specified keysym at startup. A keysym
can be prefixed by a repetition count number. You can
specify the option multiple times to simulate multiple
keystrokes. Presses entered via <b>--keysym-press</b> are
processed with the same priority as those entered via
<b>--chars-press</b>, that is, as they appear. See man
<i>fimrc</i>(5) for a list of keysyms and the use of
bind.</p>
<p style="margin-left:11%;"><b>-K</b> <i>{chars},</i>
<b>--chars-press</b> <i>{chars}</i></p>
<p style="margin-left:22%;">Input one or more keyboard
characters at program startup (simulate keyboard presses).
This option can be specified multiple times. Each additional
time (or if the string is empty), a press of Enter (ASCII
code 0x0D) key is prepended. Examples: -K ’’
simulates press of an Enter; -K ’:next;’
activates the command line and enter "next;"
without executing it; -K ":next;" -K
"next" executes "next", stays in the
command line and enter keys "next"; -K
":next;" -K "" -K "next"
executes "next", leaves the command line, and
executes in sequence any command bound to keys
’n’, ’e’, ’x’,
’t’. Presses entered via <b>--chars-press</b>
are processed with the same priority as those entered via
<b>--keysym-press</b>, that is, as they appear.</p>
<p style="margin-left:11%;"><b>-D</b> <i>{filename},</i>
<b>--load-image-descriptions-file</b> <i>{filename}</i></p>
<p style="margin-left:22%;">Load image descriptions from
file <i>{filename}</i>. Each line begins with the basename
of an image file, followed by a Tab character (or a
different character if specified via
<b>--image-descriptions-file-separator</b>), then the
description text. The description text is copied into the
<b>i:_comment</b> variable of the image at load time,
overriding the comment possibly loaded from the file (e.g.
JPEG, PNG or TIFF comment). If a ’@’ followed by
an identifier <i>{identifier}</i> is encountered, and
i:<i>{var}</i> is set, its value is substituted here. If
"@#" is encountered, the remainder of the
description line is ignored. Special comment lines like
"#!fim:<i>{var}</i>=<i>{val}</i>" lead
i:<i>{var}</i> to be assigned value <i>{val}</i> (unquoted)
at image loading time (cached variable), unless <i>{var}</i>
starts with an underscore (’_’). Special comment
lines like "#!fim:@<i>{var}</i>=<i>{val}</i>"
create a variable <i>{var}</i> that are only valid in
expanding @<i>{var}</i> in comments. Special comment lines
like "#!fim:<i>{var}</i>@=<i>{val}</i>" or
"#!fim:@<i>{var}</i>@=<i>{val}</i> (notice @ before =)
also expand whatever @<i>{identifier}</i> encountered in
<i>{val}</i> . Special comment lines like
"#!fim:+=<i>{val}</i>" add <i>{val}</i> to current
description. Special comment lines like
"#!fim:^=<i>{val}</i>" set <i>{val}</i> to be the
base of each description. Special comment lines like
"#!fim:!=" reset all cached variables. Special
comment lines like "#!fim:/=<i>{dir}</i>" prepend
<i>{dir}</i> to each file’s basename. Special comment
lines like "#!fim:\=<i>{dir}</i>" prepend
<i>{dir}</i> to each file’s name. Special description
text (to be associated to an image) begins with markers:
with "#!fim:=", the last description line is
reused; with "#!fim:+", what follows is appended
to the last description line; with "#!fim:^", what
follows is prepended to the last description line; with
"#!fim:s/<i>{f}</i>/<i>{t}</i>", the last
description line is used and substituted substring
<i>{t}</i> to occurrences of substring <i>{f}</i>
(<i>{f}</i> and <i>{t}</i> cannot contain newlines or a
’/’). If <i>{val}</i> is empty that variable is
unset. These variables are stored also in an internal index
used by the limit command. This option sets
<b>_caption_over_image</b>=2, so that a caption is displayed
over the image. A description file beginning with
"#!fim:desc" can be loaded without specifying this
switch.</p>
<p style="margin-left:11%;"><b>-S</b> <i>{sepchar},</i>
<b>--image-descriptions-file-separator</b>
<i>{sepchar}</i></p>
<p style="margin-left:22%;">A character to be used as a
separator between the filename and the description part of
lines specified just before a
--load-image-descriptions-file.</p>
<p style="margin-left:11%;"><b>-i</b>,
<b>--image-from-stdin</b></p>
<p style="margin-left:22%;">Read one single image from the
standard input (the image data, not the filename). May not
work with all supported file formats. In the image list,
this image takes the special name
"<STDIN>".</p>
<p style="margin-left:11%;"><b>--mark-from-image-descriptions-file</b>
<i>{filename}</i></p>
<p style="margin-left:22%;">Set those files specified in
<i>{filename}</i> (see --load-image-descriptions-file for
the file format) as marked (see the list command).</p>
<p style="margin-left:11%;"><b>-m</b> <i>{vmode},</i>
<b>--mode</b> <i>{vmode}</i></p>
<p style="margin-left:22%;">Name of the video mode to use
video mode (must be listed in /etc/fb.modes). Default is not
to change the video mode. In the past, the XF86 config file
(/etc/X11/XF86Config) used to contain Modeline information,
which could be fed to the modeline2fb perl script
(distributed with fbset). On many modern xorg based systems,
there is no direct way to obtain a fb.modes file from the
xorg.conf file. So instead one could obtain useful fb.modes
info by using the (fbmodes (no man page AFAIK)) tool,
written by bisqwit. An unsupported mode should make fim exit
with failure. But it is possible the kernel could trick fim
and set a supported mode automatically, thus ignoring the
user set mode.</p>
<p style="margin-left:11%;"><b>-N</b>,
<b>--no-rc-file</b></p>
<p style="margin-left:22%;">No personal initialization file
is read (default is ~/.fimrc) at startup.</p>
<p style="margin-left:11%;"><b>--no-etc-fimrc-file</b></p>
<p style="margin-left:22%;">No system-wide initialization
file is read (default is /usr/local/etc/fimrc) at startup.
See also <b>--etc-fimrc</b>.</p>
<p style="margin-left:11%;"><b>--no-internal-config</b></p>
<p style="margin-left:22%;">No internal default
configuration at startup (uses internal variable
<b>_no_default_configuration</b>). Will only provide a
minimal working configuration.</p>
<p style="margin-left:11%;"><b>--no-commandline</b></p>
<p style="margin-left:22%;">With internal command line mode
disabled.</p>
<p style="margin-left:11%;"><b>--no-history-save</b></p>
<p style="margin-left:22%;">Do not save execution history
at finalization (uses internal variable
<b>_save_fim_history</b>).</p>
<p style="margin-left:11%;"><b>--no-history-load</b></p>
<p style="margin-left:22%;">Do not load execution history
at startup.</p>
<p style="margin-left:11%;"><b>--no-history</b></p>
<p style="margin-left:22%;">Do not load or save execution
history at startup.</p>
<p style="margin-left:11%;"><b>-p</b>,
<b>--script-from-stdin</b></p>
<p style="margin-left:22%;">Read commands from stdin before
entering in interactive mode.</p>
<p style="margin-left:11%;"><b>-o
[fb|sdl|gtk|ca|aa|dumb][=</b><i>{gfxopts}</i>]<i>,</i>
<b>--output-device <br>
[fb|sdl|gtk|ca|aa|dumb][=</b><i>{gfxopts}</i>]</p>
<p style="margin-left:22%;">Use the specified <b>device</b>
(one among fb|sdl|gtk|ca|aa|dumb) as fim video output
device, overriding automatic checks. If the <b>device</b> is
empty and followed by <i>{gfxopts}</i>, it will be selected
automatically. The available devices depend on the current
environment and on the configuration and compilation
options. You can get the list of available output devices
issuing <b>fim --version</b>. The possible values to
<i>{gfxopts}</i> that we describe here can also be passed as
"display ’reinit’ <i>{gfxopts}</i>" --
see man <i>fimrc</i> for this. The device name with options
(perhaps with modifications due to auto-detection) is stored
in variable <b>_device_string</b>. The <b>fb</b> option
selects the Linux framebuffer. Presence of <i>{gfxopts}</i>
with value <b>’S’</b> (e.g.
’<b>fb=S</b>’) makes framebuffer initialization
more picky: it does not tolerate running in a screen
session. The <b>ca</b> option (coloured ASCII-art) can be
specified as
<b>ca[={[’w’][’h’][’H’][’d:’DITHERMODE]}]</b>
; if supplied, <b>’w’</b> selects windowed mode,
provided libcaca is running under X; by default (or with
<b>’W’</b>), windowed mode is being turned off
internally during initialization by unsetting the DISPLAY
environment variable. If <b>’d:’</b> is present,
the <b>DITHERMODE</b> following it will be passed as dither
algorithm string (alternatively, it can be a non-negative
number, too). The <b>aa</b> (monochrome ASCII-art) option
can be specified as
<b>aa[={[’w’|’W’]}]</b>; if
supplied, <b>’w’</b> selects windowed mode,
provided aalib is running under X; by default (or with
<b>’W’</b>), windowed mode is being turned off
internally during initialization by unsetting the DISPLAY
environment variable. Please note that the readline
(internal command line) functionality in <b>ca</b> and
<b>aa</b> modes is limited. If the graphical windowed mode
is <b>sdl</b> or <b>gtk</b> it can be followed by
<b>={[’w’][’m’][’r’][’h’][’W’][’M’][’R’][’H’][width[:height]][’%’]}</b>,
where <b>width</b> and <b>height</b> are integer numbers
specifying the desired resolution (if <b>height</b> not
specified, it takes the value of <b>width</b>); the
<b>’w’</b> character requests windowed mode
(instead of <b>’W’</b> for fullscreen); the
<b>’m’</b> character requests mouse pointer
display; the <b>’h’</b> character requests help
grid map draw (can be repeated for variants); the
<b>’r’</b> character requests support for window
resize; the <b>’%’</b> character requests to
treat <b>width</b> and <b>height</b> as percentage of
possible window resolution. The same letters uppercase
request explicit negation of the mentioned features.
Additionally, in <b>gtk</b> mode: <b>’b’</b>
hides the menu bar, <b>’e’</b> starts with empty
menus, <b>’f’</b> rebuilds the menus, and
<b>’D’</b> removes the menus. <b>Note</b>: the
<b>gtk</b> mode is a recent addition and may have defects.
The <b>sdl</b> mode works best with libsdl-2; libsdl-1.2
support is being discontinued. <br>
The <b>imlib2</b> option requests imlib2 and is unfinished:
do not use it. <br>
The <b>dumb</b> test mode is there only for test purposes
and is not interactive.</p>
<p style="margin-left:11%;"><b>--offset</b>
<i>{bytes-offset[{:upper-offset}|{+offset-range}]}</i></p>
<p style="margin-left:22%;">Use the specified <i>offset</i>
(in bytes) for opening the specified files. If
<i>:upper-offset</i> is specified, further bytes until
<i>upper-offset</i> are probed. If <i>+offset-range</i> is
specified instead, that many additional bytes are to be
probed. Use this option to search damaged file systems for
image files. Appending a modifier among
’K’,’M’,’G’ (case
irrelevant) to an offset number changes the unit to be
respectively 2^10, 2^20, or 2^30 bytes.</p>
<p style="margin-left:11%;"><b>--pread-cmd</b>
<i>{cmd-filter-pipeline}</i></p>
<p style="margin-left:22%;">Specify a shell command with
<i>{cmd-filter-pipeline}</i>. If the current filename
matches "^[/A-Za-z0-9_.][/A-Za-z0-9_.-]*$", it is
be substituted to any occurrence of ’{}’. The
resulting command output is assumed to be file data, which
is read, decoded, and displayed. This works by setting the
internal <b>_pread_cmd</b> variable (empty by default).</p>
<p style="margin-left:11%;"><b>-P</b>,
<b>--text-reading</b></p>
<p style="margin-left:22%;">Enable textreading mode. This
has the effect that fim displays images scaled to the width
of the screen, and aligned to the top. If the images you are
watching are text pages, all you have to do to get the next
piece of text is to press space (in the default key
configuration, of course).</p>
<p style="margin-left:11%;"><b>-s</b> <i>{value},</i>
<b>--scroll</b> <i>{value}</i></p>
<p style="margin-left:22%;">Set scroll steps for internal
variable <b>_steps</b> (default is "20%").</p>

<i>{number}</i></p>
<p style="margin-left:22%;">Interruptible slideshow mode.
Wait for <i>{number}</i> of seconds (can have a decimal
part, and is assigned to the _slideshow_sleep_time variable)
after each image. Implemented by executing reload;
i:fresh=1; while(_fileindex <=
_filelistlen-_loop_only_once){sleep _slideshow_sleep_time;
next;} _loop_only_once=0; sleep _slideshow_sleep_time; as a
first command. Can be interrupted by : or Esc. The other
keys execute accordingly to their function but do not
interrupt the slideshow. Like in fbi, this cycles forever,
unless <b>--once</b> is specified.</p>
<p style="margin-left:11%;"><b>--sanity-check</b></p>
<p style="margin-left:22%;">Perform a quick sanity check,
just after the initialization, and terminate.</p>
<p style="margin-left:11%;"><b>-t</b>,
<b>--no-framebuffer</b></p>
<p style="margin-left:22%;"><b>fim</b> Use an ASCII Art
driver. If present, use either of libcaca (coloured), or
aalib (monochrome). For more, see (man fimrc), (info aalib)
or (apropos caca)). If no ASCII Art driver had been enabled
at compile time, fim does not display any image at all.</p>
<p style="margin-left:11%;"><b>-T</b> <i>{terminal},</i>
<b>--vt</b> <i>{terminal}</i></p>
<p style="margin-left:22%;">The <i>{terminal}</i> is to be
used as virtual terminal device file (as in fbi). See (chvt
(1)), (openvt (1)) for more info about this. Use (con2fb
(1)) to map a terminal to a framebuffer device.</p>
<p style="margin-left:11%;"><b>--reverse</b></p>

<p style="margin-left:11%;"><b>--autowindow</b></p>
<p style="margin-left:22%;">Resize the window size (if
supported by the video mode) to the image size. Don’t
use this with other image scaling options.</p>
<p style="margin-left:11%;"><b>--no-stat-push</b></p>
<p style="margin-left:22%;">Sets <b>_push_checks</b>=0
before initialization, thus disabling file/dir existence
checks with stat(2) at push push time (and speeding up
startup).</p>
<p style="margin-left:11%;"><b>-H</b>,
<b>--autoheight</b></p>
<p style="margin-left:22%;">Scale the image according to
the screen height.</p>
<p style="margin-left:11%;"><b>-W</b> <i>{scriptfile},</i>
<b>--write-scriptout</b> <i>{scriptfile}</i></p>
<p style="margin-left:22%;">All the characters that you
type are recorded in the file <i>{scriptfile}</i>, until you
exit <b>fim</b>. This is useful if you want to create a
script file to be used with "fim -c" or
":exec" (analogous to Vim’s -s and
":source!"). If the <i>{scriptfile}</i> file
exists, it is not touched (as in Vim’s -w).</p>
<p style="margin-left:11%;"><b>-L</b>
<i>{fileslistfile},</i> <b>--read-from-file</b>
<i>{fileslistfile}</i></p>
<p style="margin-left:22%;">Read file list from a file:
each line one file to load (similar to
<b>--read-from-stdin</b>; use <b>--read-from-stdin-elds</b>
to control line breaking).</p>
<p style="margin-left:11%;"><b>-, --read-from-stdin</b></p>
<p style="margin-left:22%;">Read file list from stdin: each
line one file to load; use with --read-from-stdin-elds to
control line breaking).</p>
<p style="margin-left:22%; margin-top: 1em">Note that these
three standard input reading functionalities (-i,-p and -)
conflict : if two or more of them occur in fim invocation,
fim exits with an error and warn about the ambiguity.</p>
<p style="margin-left:22%; margin-top: 1em">See the section
<b>INVOCATION EXAMPLES</b> below to read some useful (and
unique) ways of employing fim.</p>
<p style="margin-left:11%;"><b>--read-from-stdin-elds</b>
<i>{delimiter-char}</i></p>
<p style="margin-left:22%;">Specify an endline delimiter
character for breaking lines read via
-/--read-from-stdin/--read-from-file (which shall be
specified after this). Line text before the delimiter are be
treated as names of files to load; the text after is
ignored. This is also useful e.g. to load description files
(see --load-image-descriptions-file) as filename list files.
Default is the newline character (0x0A); to specify an ASCII
NUL byte (0x00) use ’’.</p>
<p style="margin-left:11%;"><b>-A</b>, <b>--autotop</b></p>
<p style="margin-left:22%;">Align images to the top border
(by setting ’<b>_autotop</b>=1’ after
initialization).</p>
<p style="margin-left:11%;"><b>-q</b>, <b>--quiet</b></p>
<p style="margin-left:22%;">Quiet execution mode. Sets
_display_status=0;_display_busy=0;.</p>
<p style="margin-left:11%;"><b>-r</b>
<i>{{width:height}|’fullscreen’},</i>
<b>--resolution</b> <i><br>
{{width:height}|’fullscreen’}</i></p>
<p style="margin-left:22%;">Set resolution specification in
pixels dimensions. Supported only by GTK and SDL. Will be
appended to the argument to --output-device. Shorthand value
’fullscreen’ is translated as
’W’.</p>
<p style="margin-left:11%;"><b>-R[</b><i>{exp}</i>]<i>,</i>
<b>--recursive[=</b><i>{exp}</i>]</p>
<p style="margin-left:22%;">Push files/directories to the
files list recursively. The expression in variable
<b>_pushdir_re</b> (default:
".(JPG|PNG|GIF|BMP|TIFF|TIF|JPEG|JFIF|PPM|PGM|PBM|PCX|QOI|AVIF|WEBP)$")
lists extensions of filenames which are loaded in the list.
You can overwrite its value by optionally passing an
expression <i>{exp}</i> here as argument. If starting with
’+’ or ’|’, the expression following
is to be appended to it.</p>
<p style="margin-left:11%;"><b>-X</b>,
<b>--no-pipe-load</b></p>
<p style="margin-left:22%;">Do not load via external
converter programs: only use built-in file decoders.</p>
<p style="margin-left:11%;"><b>-B</b>,
<b>--background-recursive</b></p>
<p style="margin-left:22%;">Push files/directories to the
files list recursively, in background during program
execution. Any sorting options are ignored. Experimental
feature, unfinished.</p>
<p style="margin-left:11%;"><b>--load-shadow-directory</b>
<i>{dirname}</i></p>
<p style="margin-left:22%;">Add <i>{dirname}</i> to the
shadow directory list. Then ’scale
"shadow"’ temporarily substitutes the image
being displayed with that of the first same-named file
located under a shadow directory. Useful to browse low-res
images, but still being able to quickly view the hi-res
original residing in a shadow directory. This works as
intended as long as unique filenames are involved.</p>
<p style="margin-left:11%;"><b>-/</b> <i>{pattern},</i>
<b>--/</b> <i>{pattern}</i></p>
<p style="margin-left:22%;">After startup jump to pattern;
short for -c ’/’ <i>{pattern}</i>.</p>

<i>{pattern}</i></p>
<p style="margin-left:22%;">After startup jump to pattern;
as -c ’/’<i>{pattern}</i> but with search on the
full path (with <b>_re_search_opts="f"</b>).</p>
<p style="margin-left:11%;"><b>-1</b>, <b>--once</b></p>
<p style="margin-left:22%;">If running --slideshow, loop
only once (as in fbi).</p>
<h2>PROGRAM RETURN STATUS

<h2>COMMON PROBLEMS
<a name="COMMON PROBLEMS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>fim -o
fb</b> needs read-write access to the framebuffer devices
(/dev/fbN or /dev/fb/N), i.e you (our your admin) have to
make sure fim can open the devices in rw mode. The IMHO most
elegant way is to use pam_console (see
/etc/security/console.perms) to chown the devices to the
user logged in on the console. Another way is to create some
group, chown the special files to that group and put the
users which are allowed to use the framebuffer device into
the group. You can also make the special files world
writable, but be aware of the security implications this
has. On a private box it might be fine to handle it this way
through.</p>
<p style="margin-left:11%; margin-top: 1em">If using udev,
you can edit: /etc/udev/permissions.d/50-udev.permissions
and set these lines like here: <br>
# fb devices <br>
fb:root:root:0600 <br>
fb[0-9]*:root:root:0600 <br>
fb/*:root:root:0600</p>
<p style="margin-left:11%; margin-top: 1em"><b>fim -o
fb</b> also needs access to the linux console (i.e.
/dev/ttyN) for sane console switch handling. That is
obviously no problem for console logins, but any kind of
pseudo tty (xterm, ssh, screen, ...) will <b>not</b>
work.</p>

<h2>NOTES
<a name="NOTES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">This manual
page is neither accurate nor complete. In particular, issues
related to driver selection shall be described more
accurately. Also the accurate sequence of autocommands
execution, variables application is critical to
understanding fim, and should be documented. The filename
"<STDIN>" is reserved for images read from
standard input (view this as a limitation), and thus
handling files with such name may incur in limitations.</p>
<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>fim</b> has
bugs. Please read the <b>BUGS</b> file shipped in the
documentation directory to discover the known ones. There
are also inconsistencies in the way the internal command
line works across the different graphical devices.</p>
