.SH DESCRIPTION
The
.I \*(n)
program is used to manipulate the file headers within
.IR tar (1)
archive files.
.PP
This is useful when preparing sources for Internet archive sites,
and you don't want to included details of your development environment
in the
.IR tar (1)
file.
.PP
One of the most useful features is the ability to add a prefix to the
names of the files within the
.IR tar (1)
file.
An example is adding the prefix ".",
for when you have a
.IR tar (1)
file with absolute paths in it,
and need to extract the file with relative paths.
.PP
The GNU tar format headers are understood,
including extended names.
.PP
If no input file is named,
or the special name "-" is used,
input will be read from the standard input.
Similarly,
if no output file is named,
or the special name "-" is used,
output will be written to the standard output.
.SH OPTIONS
The following options are understood:
.TP 8n
\fB\-Block_Size\fP \fInumber\fP
Thsi option many be used to specify the block size, as a multiple of
512 bytes.  The default is \f[CW]-bs=20\fP resulting in a 10KB block size.
.TP 8n
.B -Clean_Meta
.br
This option may be used to
ensure that file names do not contain shell meta characters.
If any are found, they are replaced by a hyphen (-) character.
Warning: duplicate file names may result.
.TP 8n
.B -Clean_Print
.br
This option may be used to
ensure that file names only contain printable ascii characters.
If any non-printable characters are found,
they are replaced by a hyphen (-) character.
Warning: duplicate file names may result.
.TP 8n
.B -Clean_Space
.br
This option may be used to
ensure that file names contain no white space characters.
If any are found, they are replaced by a hyphen (-) character.
Warning: duplicate file names may result.
.TP 8n
.B -Clean
.br
This option is a terse way of specifying all of the above 3 options.
.TP 8n
.B -DownCase
.br
This option may be used to
force file names to be all lower case.
Warning: duplicate file names may result.
.TP 8n
\fB-Group\fP \fIarg\fP
.br
This option may be used to set both
the group name and group number fields
in the header of every file in the archive file.
The argument may be either a string or a number.
It is an error if a corresponding entry cannot be found in the
.I /etc/group
file.
.TP 8n
\fB-Group_NAme\fP \fIstring\fP
.br
This option is used to 
set the group name field in the header
of every file in the archive file.
The string may be any arbitrary string,
it is not restricted to a known group.
.TP 8n
\fB-Group_NAme\fP \fInumber\fP
.br
This option is used to 
set the group name field in the header
of every file in the archive file.
The number is mapped to a group name through the
.I /etc/group
file.
It is an error if a corresponding group cannot be found.
.TP 8n
\fB-Group_NUmber\fP \fIstring\fP
.br
This option is used to 
set the group number field in the header
of every file in the archive file.
The string is mapped to a group number through the
.I /etc/group
file.
It is an error if a corresponding group cannot be found.
.TP 8n
\fB-Group_NUmber\fP \fInumber\fP
.br
This option is used to 
set the group number field in the header
of every file in the archive file.
The number may be any arbitrary number,
it is not restricted to a known group.
.so o_help.so
.TP 8n
\fI\-Input_ForMaT\fP \fIname\fP
.RS
This option may be used to specify the input format to be used.
The input \fIname\fPs are
.TP 8n
tar
This format understands all of the various \fItar\fP(1) formats.
This is the default.
.TP 8n
list
The input is a text file which contains one file name per line.
The named files are read as if they were the input.
It is common for \fIfind\fP(1) to be used to form the list of file names.
.PP
Any other format name will produce an error.
.RE
.TP 8n
.B -List
.br
Give a terse listing of the file headers on the standard error
as they are written to the output.
.TP 8n
.B -No_Directories
.br
This option may be used to supress directories
from the output.
This can be useful when the archive has been created with
directories in useless modes.
.TP 8n
\fB-Mode_Clear\fP \fIbits\fP
.br
This option may be used to
set the mode of each file in the archive file.
The
.I bits
specified are cleared in the mode.
You should use an octal number with a leading zero as the argument;
if you omit the leading zero it will be interpreted as decimal.
The
.B -Mode_Set
option is applied first,
the
.B -Mode_Clear
option is applied specond;
if neither is specified the mode of each file is unaltered.
.TP 8n
\fB-Mode_Set\fP \fIbits\fP
.br
This option may be used to set the
mode of each file in the archive file.
The
.I bits
specified are set in the mode.
You should use an octal number with a leading zero as the argument;
if you omit the leading zero it will be interpreted as decimal.
.TP 8n
.B -Now
.br
Set the last-time-modified field of the headers to the current time,
all files will be giben the same time.
.TP 8n
.B -Old_Type
.br
By default,
\*(n) corrects the old normal file
type into the modern normal file type.
This option requests that old normal file
type indicators remain unaltered.
.TP 8n
\fB\-Output_ForMaT\fP \fIname\fP
.RS
This option may be used to specify the output format to be used.
The output \fIname\fPs are
.TP 8n
ustar
The format that GNU tar uses.
This is the default.
.TP 8n

.PP
Any other format name will produce an error.
.RE
.TP 8n
\fB-Prefix\fP \fIstring\fP
.br
This option is used to add a prefix directory name to the
name of every file in the archive file.
.TP 8n
\fB\-PROgress\fP
This option is used to obtain a progress indicator.
Only works in combination with the \fI\-\-ifmt=list\fP option.
.\" ------------------------------------------------------------------------
.TP 8n
\fB-Remove_Prefix\fP \fInumber\fP
.br
This option is used to remove a number of leading directories from
the name of every file in the archive file,
if present.
The prefixes will be removed before any prefix specified by the
.B -Prefix
option is prepended.
.\" ------------------------------------------------------------------------
.TP 8n
\fB-Remove_Prefix\fP \fIstring\fP
.RS
This option is used to remove a prefix directory name from
the name of every file in the archive file,

This option may be given more than once,
and as many of the prefixes as appear will be removed.
The prefixes will be removed before any prefix specified by the
.B -Prefix
option is prepended.
.PP
This option is potentially ambiguous with the preceeding option, if you
wish to remove a leading prefix which looks like a number.  If this is
the case, add a slash ("/") to the end of the prefix to stop it looking
like a number.
