This tool allows you to discover filesystems, partitions, logical volumes,
and their sizes in a disk image or virtual machine.  It is a replacement for
\&\fIvirt\-list\-filesystems\fR\|(1) and \fIvirt\-list\-partitions\fR\|(1).
.PP
One use for this tool is from shell scripts to iterate over all filesystems
from a disk image:
.PP
.Vb 3
\& for fs in $(virt\-filesystems \-a disk.img); do
\&   # ...
\& done
.Ve
.PP
Another use is to list partitions before using another tool to modify those
partitions (such as \fIvirt\-resize\fR\|(1)).  If you are curious about what an
unknown disk image contains, use this tool along with \fIvirt\-inspector\fR\|(1).
.PP
Various command line options control what this program displays.  You need
to give either \fI\-a\fR or \fI\-d\fR options to specify the disk image or libvirt
guest respectively.  If you just specify that then the program shows
filesystems found, one per line, like this:
.PP
.Vb 3
\& $ virt\-filesystems \-a disk.img
\& /dev/sda1
\& /dev/vg_guest/lv_root
.Ve
.PP
Якщо ви додасте \fI\-l\fR або \fI\-\-long\fR, у виведених даних буде показано
додаткову інформацію:
.PP
.Vb 4
\& $ virt\-filesystems \-a disk.img \-l
\& Name                   Type         VFS   Label  Size
\& /dev/sda1              filesystem   ext4  boot   524288000
\& /dev/vg_guest/lv_root  filesystem   ext4  root   10212081664
.Ve
.PP
If you add \fI\-\-extra\fR then non-mountable (swap, unknown) filesystems are
shown as well:
.PP
.Vb 5
\& $ virt\-filesystems \-a disk.img \-\-extra
\& /dev/sda1
\& /dev/vg_guest/lv_root
\& /dev/vg_guest/lv_swap
\& /dev/vg_guest/lv_data
.Ve
.PP
If you add \fI\-\-partitions\fR then partitions are shown instead of filesystems:
.PP
.Vb 3
\& $ virt\-filesystems \-a disk.img \-\-partitions
\& /dev/sda1
\& /dev/sda2
.Ve
.PP
Similarly you can use \fI\-\-logical\-volumes\fR, \fI\-\-volume\-groups\fR,
\&\fI\-\-physical\-volumes\fR, \fI\-\-block\-devices\fR to list those items.
.PP
You can use these options in combination as well (if you want a combination
including filesystems, you have to add \fI\-\-filesystems\fR).  Notice that some
items fall into several categories (eg. \f(CW\*(C`/dev/sda1\*(C'\fR might be both a
partition and a filesystem).  These items are listed several times.  To get
a list which includes absolutely everything that virt-filesystems knows
about, use the \fI\-\-all\fR option.
.PP
UUIDs (because they are quite long) are not shown by default.  Add the
\&\fI\-\-uuid\fR option to display device and filesystem UUIDs in the long output.
.PP
\&\fI\-\-all \-\-long \-\-uuid\fR is a useful combination to display all possible
information about everything.
.PP
.Vb 7
\& $ virt\-filesystems \-a win.img \-\-all \-\-long \-\-uuid \-h
\& Name      Type       VFS  Label           Size Parent   UUID

.PD
Add \fIfile\fR which should be a disk image from a virtual machine.  If the
virtual machine has multiple block devices, you must supply all of them with
separate \fI\-a\fR options.
.Sp
The format of the disk image is auto-detected.  To override this and force a
particular format use the \fI\-\-format=..\fR option.
.IP "\fB\-\-all\fR" 4
.IX Item "--all"
Display everything.  This is currently the same as specifying these options:
\&\fI\-\-filesystems\fR, \fI\-\-extra\fR, \fI\-\-partitions\fR, \fI\-\-block\-devices\fR,

.Sp
If you specify guest block devices directly (\fI\-a\fR), then libvirt is not
used at all.
.IP "\fB\-\-csv\fR" 4
.IX Item "--csv"
Write out the results in \s-1CSV\s0 format (comma-separated values).  This format
can be imported easily into databases and spreadsheets, but read \*(L"\s-1NOTE\s0

instead of names.
.IP "\fB\-\-echo\-keys\fR" 4
.IX Item "--echo-keys"
When prompting for keys and passphrases, virt-filesystems normally turns
echoing off so you cannot see what you are typing.  If you are not worried
about Tempest attacks and there is no one else in the room you can specify
this flag to see what you are typing.
.IP "\fB\-\-extra\fR" 4
.IX Item "--extra"
This causes filesystems that are not ordinary, mountable filesystems to be
displayed.  This category includes swapspace, and filesystems that are empty
or contain unknown data.
.Sp
This option implies \fI\-\-filesystems\fR.
.IP "\fB\-\-filesystems\fR" 4
.IX Item "--filesystems"
Display mountable filesystems.  If no display option was selected then this
option is implied.
.Sp
With \fI\-\-extra\fR, non-mountable filesystems are shown too.

.PD
The default for the \fI\-a\fR option is to auto-detect the format of the disk
image.  Using this forces the disk format for \fI\-a\fR options which follow on
the command line.  Using \fI\-\-format\fR with no argument switches back to
auto-detection for subsequent \fI\-a\fR options.
.Sp
Приклад:

.Sp
forces raw format (no auto-detection) for \f(CW\*(C`disk.img\*(C'\fR and reverts to
auto-detection for \f(CW\*(C`another.img\*(C'\fR.
.Sp
If you have untrusted raw-format guest disk images, you should use this
option to specify the disk format.  This avoids a possible security problem
with malicious guests (\s-1CVE\-2010\-3851\s0).

.IP "\fB\-\-keys\-from\-stdin\fR" 4
.IX Item "--keys-from-stdin"
Read key or passphrase parameters from stdin.  The default is to try to read
passphrases from the user by opening \f(CW\*(C`/dev/tty\*(C'\fR.
.IP "\fB\-l\fR" 4

.PD 0
.IP "\fB\-\-long\fR" 4

.PD
Display extra columns of data (\*(L"long format\*(R").
.Sp
A title row is added unless you also specify \fI\-\-no\-title\fR.
.Sp
The extra columns displayed depend on what output you select, and the
ordering of columns may change in future versions.  Use the title row,
\&\fI\-\-csv\fR output and/or \fIcsvtool\fR\|(1) to match columns to data in external
programs.
.Sp
Use \fI\-h\fR if you want sizes to be displayed in human-readable format.  The
default is to show raw numbers of \fIbytes\fR.

Use \fI\-\-uuid\fR to display UUIDs too.

The object type, for example \f(CW\*(C`filesystem\*(C'\fR, \f(CW\*(C`lv\*(C'\fR, \f(CW\*(C`device\*(C'\fR etc.
.IP "\fB\s-1VFS\s0\fR" 4
.IX Item "VFS"
If there is a filesystem, then this column displays the filesystem type if
one could be detected, eg. \f(CW\*(C`ext4\*(C'\fR.
.IP "\fBМітка\fR" 4
.IX Item "Мітка"
If the object has a label (used for identifying and mounting filesystems)
then this column contains the label.
.IP "\fB\s-1MBR\s0\fR" 4
.IX Item "MBR"
The partition type byte, displayed as a two digit hexadecimal number.  A
comprehensive list of partition types can be found here:
http://www.win.tue.nl/~aeb/partitions/partition_types\-1.html <http://www.win.tue.nl/~aeb/partitions/partition_types-1.html>
.Sp
Це стосується лише розділів \s-1DOS\s0 (\s-1MBR\s0).
.IP "\fBРозмір\fR" 4
.IX Item "Розмір"
The size of the object in bytes.  If the \fI\-\-human\fR option is used then the
size is displayed in a human-readable form.
.IP "\fBОснова\fR" 4
.IX Item "Основа"
The parent column records the parent relationship between objects.
.Sp
For example, if the object is a partition, then this column contains the
name of the containing device.  If the object is a logical volume, then this
column is the name of the volume group.
.Sp
If there is more than one parent, then this column is (internal to the
column) a comma-separated list, eg. \f(CW\*(C`/dev/sda,/dev/sdb\*(C'\fR.
.IP "\fB\s-1UUID\s0\fR" 4
.IX Item "UUID"
If the object has a \s-1UUID\s0 (used for identifying and mounting filesystems and
block devices) then this column contains the \s-1UUID\s0 as a string.
.Sp
The \s-1UUID\s0 is only displayed if the \fI\-\-uuid\fR option is given.

.IX Header "ЗАУВАЖЕННЯ ЩОДО ФОРМАТУ CSV"
Comma-separated values (\s-1CSV\s0) is a deceptive format.  It \fIseems\fR like it
should be easy to parse, but it is definitely not easy to parse.

Myth: Just split fields at commas.  Reality: This does \fInot\fR work
reliably.  This example has two columns:
.PP
.Vb 1
\& "foo,bar",baz
.Ve
.PP
Myth: Read the file one line at a time.  Reality: This does \fInot\fR work
reliably.  This example has one row:
.PP
.Vb 2
\& "foo
\& bar",baz
.Ve
.PP
For shell scripts, use \f(CW\*(C`csvtool\*(C'\fR (<http://merjis.com/developers/csv> also
packaged in major Linux distributions).
.PP
For other languages, use a \s-1CSV\s0 processing library (eg. \f(CW\*(C`Text::CSV\*(C'\fR for Perl
or Python's built-in csv library).
.PP
Most spreadsheets and databases can import \s-1CSV\s0 directly.

Libvirt guest names can contain arbitrary characters, some of which have
meaning to the shell such as \f(CW\*(C`#\*(C'\fR and space.  You may need to quote or
escape these characters on the command line.  See the shell manual page
\&\fIsh\fR\|(1) for details.
