       aunpack [OPTION]... ARCHIVE [FILE]...
       apack [OPTION]... ARCHIVE [FILE]...
       als [OPTION]... ARCHIVE [FILE]...

       arepack [OPTION]...OLD-ARCHIVE NEW-ARCHIVE

DESCRIPTION

       This  manual  page  document  describes  the  atool commands.  These commands are used for
       managing file archives of various types, such as tar and Zip archives. Each command can be
       executed individually or by giving the appropriate options to atool (see OPTIONS below).

       aunpack extracts files from an archive. Often one wants to extract all files in an archive
       to a single subdirectory.  However, some archives contain multiple  files  in  their  root
       directories.  The  aunpack  program  overcomes this problem by first extracting files to a
       unique (temporary) directory, and then moving its contents back  if  possible.  This  also
       prevents local files from being overwritten by mistake.

       apack  creates  archives  (or  compresses  files).  If  no  file  arguments are specified,
       filenames to add are read from standard in.

       als lists files in an archive.

       acat extracts files in an archive to standard out.

       adiff generates a diff between two archives using diff(1).

       arepack repacks archives to a different format. It does this by first extracting all files
       of  the  old  archive into a temporary directory, then packing all files extracted to that
       directory to the new archive. Use the --each (-e) option in combination with --format (-F)
       to repack multiple archives using a single invocation of atool. Note that arepack will not
       remove the old archive.

       Unless the --format (-F) option is provided, the  archive  format  is  determined  by  the
       archive file extension. I.e.  an extension ".tar.gz" or ".tgz" means tar+gzip format. Note
       that the extensions are checked in the order listed in the section  ARCHIVE  TYPES  below,
       which is why a file with extension ".tar.gz" is considered to a be tar+gzip archive, not a
       gzip compressed file.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options  starting  with
       two dashes (`-').  A summary of options is included below.

       -l, --list
              List files in archive.  This option is automatically assumed when als is executed.

       -x, --extract
              Extract  files  from archive.  This option is automatically assumed when aunpack is
              executed.

       -X, --extract-to=PATH
              Extract files from archive to the specified directory.  When  unpacking  compressed
              files, PATH may refer to either a filename or an existing directory.

       -a, --add
              Create archive.  This option is automatically assumed when apack is executed.

       -c, --cat
              Extract a file from archive to standard out (displaying it on screen).  This option
              is automatically assumed when acat is executed.

       -d, --diff
              Extract two archives and use diff(1) to generate differencies between  them.   This
              option is automatically assumed when adiff is executed.

       -e, --each
              For  each  argument,  execute  the  specified  command. This can be used to quickly
              extract, list or create multiple archives (see EXAMPLES below). This option can not
              be used with the cat command.

       -F, --format=EXTENSION
              Specify archive format manually (see ARCHIVE TYPES below).

       -S, --simulate
              Run  atool  in  simulation mode. No changes to the filesystem (i.e. writes) will be
              made, and all commands that would be executed are displayed  instead.  This  option
              can't be combined with --explain (since it implies that already).

              Note that it is not guaranteed that the commands printed in simulation mode will be
              the same as those executed in non- simulation mode. This is because some operations
              depend  on  what  files archives contain, and atool can at this time only determine
              that by extracting archives.

       -E, --explain
              Display commands executed by atool. This option can't be combined with --simulate.

       -p, --page
              Run output through a pager, usually pager unless the environment variable PAGER  is
              set.

       -f, --force
              When  extracting  from  files,  allow overwriting of local files.  When creating an
              archive, allow the archive file to be overwritten if it already exists.  Note  that
              it  is possible to add files to existing RAR and Zip archives (this is not possible
              for many other formats).

       -D, --subdir
              When extracting archives, always create a new directory for the archive even if the
              archive only contains one file in its root directory.

       -0, --null
              If  no  file arguments are specified when creating or adding files to archives, the
              list of files will  be  read  from  standard  in.   Normally  these  filenames  are
              separated  by  newline, but with this option they are separated by null-bytes. This
              is useful with the GNU find -print0 option.

       -q, --quiet
              Decrease verbosity level by one. This is  subtracted  from  the  default  verbosity
              level,  or  the level specified with --verbosity. This option may be specified more
              than once to make atool even less verbose.

       -v, --verbose
              Increase verbosity level by one. This is added to the default verbosity  level,  or
              the  level  specified with --verbosity. This option may be specified more than once
              to make atool even more verbose.

       -V, --verbosity=LEVEL
              Specify verbosity level. The default level is 1, which means "normal  verbosity"  -
              e.g. when creating and extracting from archives, files will be listed.

       --config=FILE
              Load configuration from the specified file. When using this option, the system-wide
              and user-wide configuration files will not be loaded. If the  specified  file  does
              not exist or can not be read, atool will terminate with an error message.

       -o, --option=KEY=VALUE
              Override  a configuration option. These are applied after reading the configuration
              files.

              You can specify this multiple times to override different options.

       -O, --format-option=OPTION
              Send additional options to the archiver command. This can be useful when specifying
              compression options for some archives, e.g.
                      apack -F7z -O-mx=9 archive.7z dir
              You can specify this multiple times add different options.

       --save-outdir=FILE
              When  extracting  files,  save  the  name  of  the  directory which the archive was
              extracted to to the specified file. If  the  command  was  not  `extract',  or  the
              archive  was  not extracted to a new directory, then nothing will be written to the
              specified file. If multiple archives were specified (with -e), then only  the  last
              directory that files were extracted to will be written to FILE.

              This option is used internally (see EXAMPLES below).

       --help Show summary of options.

       --version
              Output version information and exit.

ARCHIVE TYPES

       Unless  the  -f  (--format)  option  is  provided, the archive format is determined by the
       archive file extension. I.e. an extension ".tar.gz" or ".tgz" means tar+gzip format.  Note
       that  the  extensions  are  checked  in  the  other listed above, which is why a file with
       extension ".tar.gz" is considered to a tar+gzip archive, not a gzip archive.

       The diff command is supported whenever the extract command is supported.

       The supported archive types are:

       tar+gzip (.tar.gz, .tgz)
              All commands are supported.

              List, extract and add commands are supported.

       arc (.arc)
              All  command  are  supported.  (Note that arc outputs an extra newline when the cat
              command is used.)

       rpm (.rpm)
              Extract and list commands are supported.

       deb (.deb)

       lzop (.lzo)
              Extract and add commands are supported. The cat command is  not  supported  because
              lzop does not want to extract files to standard out unless the -f flag is given.

       lzip (.lz)
              Cat, extract, and add commands are supported.

              Extract and add commands are supported.

       7zip (.7z)
              All  commands  are  supported.   (Note  that 7z refuses to write extracted files to
              standard out if standard out is a terminal. Use -p or pipe the output of atool/acat
              to a pager when reading in a terminal.)

       cpio (.cpio)
              List, extract and add commands are supported.

CONFIGURATION

       Since version 0.8.0, atool can read custom configuration files.  First, hardcoded defaults
       in the atool program file are evaluated.  Then system-wide configuration values are loaded
       from  /etc/atool.conf  if  that  file  exists.  Finally, per-user configuration values are
       loaded from .atoolrc in the current user's home directory.

       The format of the configuration files is simple:

              variable value

       Here variable is a variable listed below, and value is the value to associate the variable
       with.  variable  and  value  should  be separated with at least one whitespace (space, tab
       etc). Empty lines and lines beginning with # are discarded.

       A value of `1' means that the option is enabled, and `0'  that  it  is  disabled.  Strings
       should  not  be quoted, as they start at the first non-whitespace character and end at the
       end of the line.

       The options are:

       use_tar_bzip2_option (default: 1)
              Enable this if you use GNU tar and it supports the  --bzip2  option  for  filtering
              bzip2'ed  files through bzip2. Versions 1.13.6 or later of GNU tar support --bzip2.
              Therefore, if you use GNU tar earlier than 1.13.6, you will need  to  disable  this
              option.

              This used to be use_tar_j_option but using --bzip2 is more portable.

       use_tar_z_option (default: 1)
              Enable  this if you use GNU tar and it supports the -z option for filtering gzipped
              files through gzip. You will need to disable this and use_tar_j_option if you don't
              use GNU tar.

              Disabling these two options doesn't mean that atool can't extract bzip2/gzip files.
              If disabled, atool use a pipe to send output from bzip2/gzip to tar instead.

              If possible, these options should be enabled since error management is better  when
              filtering is done by tar.

       use_tar_lzma_option (default: 1)
              Enable this if you use GNU tar and it supports the --lzma option for filtering lzma
              compressed files through lzma. Versions 1.20 or later of GNU tar support --lzma.

       use_tar_lzop_option (default: 0)
              Enable this if you use GNU tar and it supports the --lzop option for filtering lzop
              compressed files through lzop. Versions 1.21 or later of GNU tar support --lzop.

       use_tar_xz_option (default: 0)
              Enable  this  if  you  use GNU tar and it supports the --xz option for filtering xz
              compressed files through xz. Versions 1.22 or later of GNU tar support --xz.

       use_gzip_for_z (default: 1)
              Enable this if you want to  use  gzip  instead  of  uncompress  when  decompressing
              compress'ed files (`.Z' files).

       use_rar_for_unpack (default: 0)
              Enable  this  if  you  want  to always use rar instead of unrar when possible. This
              makes atool use the rar command (path_rar) even when  listing  and  extracting  RAR
              files.

       use_arc_for_unpack (default: 0)
              Enable  this  if  you want to always use arc instead of nomarch when possible. This
              makes atool use the arc command (path_arc) even when  listing  and  extracting  ARC
              files.

       use_arj_for_unpack (default: 0)
              Enable  this  if  you  want  to always use arj instead of unarj when possible. This
              makes atool use the arj command (path_arj) even when  listing  and  extracting  ARJ
              files.

       use_find_cpio_print0 (default: 1)
              Enable  this  if  find supports the -print0 option and cpio supports the -0 option.
              Without it, it is impossible/harder to make cpio archives  of  files  with  newline
              characters in their names.

       extract_deb_control (default: 1)
              Debian  .deb  package  files  contain  control  information  in a DEBIAN directory,
              especially the package's "control" file.  Enable  this  if  you  want  the  control
              information to be exctracted during extraction in addition to the normal files.

       strip_unknown_ext (default: 1)
              Certain types of files are actually archives, but their extensions doesn't tell so.
              Examples are Open Office documents (Zip  files)  and  Gnumeric  documents  (gzip'ed
              files).  Since  the  extensions of those filenames are unknown to atool, they would
              not be stripped with this option set to 0. The output file in that  case  would  be
              something like Unpack-XYZW. Setting this option to 1 will cause the extension to be
              stripped instead.

       use_pbzip2 (default: 0)
              Enable this if you want to use pbzip2  rather  than  bzip2.   Please  not  that  if
              use_tar_bzip2_option  is  enabled, then bzip2 will be used by tar regardless of the
              use_pbzip2 option. So if you  want  tar  to  use  pbzip2  rather  than  bzip2,  set
              use_pbzip2 to 1 and use_tar_bzip2_option to 0.

       use_jar (default: 0)
              Enable  this  if you want to use jar for managing jar archives. If you disable this
              option, zip will be used (which should work just as well, and  probably  be  faster
              too).

              This  option  is disabled by default since extracting files to standard out (`cat')
              is not supported by jar.

       use_file (default: 1)
              Enable this if you want atool to identify file types using file(1) for those  files
              with an unrecognized extension (or none at all).

       use_file_always (default: 0)
              Enable this if you want atool to always identify archives using file(1), regardless
              of the file extension. Please note that this currently has some drawbacks, such  as
              not  being  able  to identify all archive types (especially tar archives compressed
              with 7zip, lzop, szip etc).

       tmpdir_name (default: Unpack-%04d)
              atool extracts to a temporary directory created in the current directory so that no
              files  are  overwritten. This variable controlls what name that temporary directory
              should have.

              The `%d' string in this variable will be replaced with a random  number  between  0
              and  9999.  It is possible change the format of this number by using something else
              than `%d' - see printf(3).

       tmpfile_name (default: Pack-%04d)
              When using pbzip2, and creating archives, a temporary file need to be created. This
              option  controls the name of that file.  See tmpdir_name for further details on the
              format.

       path_pager (default: pager)

       path_jar (default: jar)

       path_tar (default: tar)

       path_zip (default: zip)

       path_unzip (default: unzip)

       path_gzip (default: gzip)

       path_bzip (default: bzip)

       path_bzip2 (default: bzip2)

       path_pbzip2 (default: pbzip2)

       path_compress (default: compress)

       path_lzma (default: lzma)

       path_lzop (default: lzop)

       path_lzip (default: lzip)

       path_rar (default: rar)

       path_unrar (default: unrar)

       path_cabextract (default: cabextract)

       path_7z (default: 7z)

       path_unalz (default: unalz)

       path_lha (default: lha)

       path_unace (default: unace)

       path_ar (default: ar)

       path_arj (default: arj)

       path_unarj (default: unarj)

       path_arc (default: arc)

       path_nomarch (default: nomarch)

       path_rpm (default: rpm)

       path_rpm2cpio (default: rpm2cpio)

       path_dpkg_deb (default: dpkg-deb)

       path_cpio (default: cpio)

       path_file (default: file)

       path_find (default: find)

       path_xargs (default: xargs)

       path_cat (default: cat)

       path_diff (default: diff)
              These are all paths to the corresponding programs. It is usually best to leave them
              as is, because that way their locations can be looked up from the PATH variable.

       args_diff (default: -ru)
              This  variable  specifies  command  line  arguments to pass to the diff command (as
              specified by path_diff) when using adiff. Space characters  separate  arguments  in
              this string.

       path_syscfg (default: /etc/atool.conf)
              (This variable can only be set in the atool program file.)  This variable specifies
              the directory where the system-wide configuration file is located.

       path_usercfg (default: .atoolrc)
              (This variable  can  only  be  set  in  the  atool  program  file  and  system-wide
              configuration  file.)  This variable specifies where the user configuration file is
              located. Note that if this filename is relative (i.e. doesn't being with  `/'),  it
              will  be  relative  to the current user's home directory (as determined by the HOME
              environment variable).

       default_verbosity (default: 1)
              This is the default verbosity of atool. By using -q and -v options,  the  verbosity
              level  can  be  raised  and  lowered.  Level 1 means "normal verbosity" - e.g. when
              creating and extracting from archives, files will be listed.

       show_extracted (default: 1)
              If this is set to 1, the aunpack command will always show what  file  or  directory
              that  was  extracted.  Otherwise  that  will  only  be  printed  if the archive was
              extracted to an unexpected location (as a result of local files already existing or
              the archive having multiple files in its root directory).

              This  can  be  quite  useful in combinatiaon with `default_verbosity 0'.  Note that
              this option will have no effect when the -X option is used with aunpack, and it has
              no effect on compressed files.

       keep_compressed (default: 1)
              When  compressing  a  file  with gzip or bzip2, the original (uncompressed) file is
              usually deleted once it has been compressed. I.e. if you compress a file "test" you
              will  end  up  with  only one file, "test.gz".  With this option set to 1, you will
              make atool keep the original file as well. The original behaviour  is  achieved  by
              setting this option to 0.

              This  option  also has an equivalent effect on uncompressing compressed files. When
              set to 1, the original (compressed) file  will  be  kept.   Otherwise  it  will  be
              deleted.

              Note  however that this option has no effect when packing up a compressed file with
              the -X option (for specifying an output  directory  or  file).  In  that  case  the
              original file is always kept.

       decompress_to_cwd (default: 1)
              When  decompressing  a  file  with commands such as gzip or bzip2, the decompressed
              file is usually placed in the same directory as  the  compressed  file.  With  this
              option  set  to  1,  the decompressed file is instead placed in the current working
              directory.

              Note that this option has no effect when -X is used.

ENVIRONMENT VARIABLES

       PAGER The default pager to use when the -p/--page option is specified.

EXAMPLES

       To extract all files from archive  `foobar.tar.gz'  to  a  subdirectory  (or  the  current
       directory if it only contains one file):
            aunpack foobar.tar.gz

       To extract all files from all `.tar.gz' archives in the current directory:
            aunpack -e *.tar.gz

       To create a zip archive of two files `foo' and `bar':
            apack myarchive.zip foo bar

       To display the file `baz' in the archive `myarchive.zip' through a pager:
            acat -p myarchive.zip baz

       To list contents of the rar archive `stuff.rar':
            als stuff.rar

       To  create  three  archives,  `dir1.tar.gz',  `dir2.tar.gz' and `dir3.tar.gz', so that the
       first one contains all files in dir1, the second all in dir2 and the third all dir3:
            apack -e -F .tar.gz dir1 dir2 dir3

       To show all differences between version 2.4.17 and 2.4.18 of the kernel:
            adiff linux-2.4.17.tar.gz linux-2.4.18.tar.gz

       To repack all .tar.gz archives in the current directory to .tar.7z (the old  archive  will
       be kept untouched):
            arepack -F.tar.7z -e *.tar.gz

       Here's a shell function that will make the aunpack command change into the directory where
       files were extracted:
            aunpack () {
              TMP=`mktemp /tmp/aunpack.XXXXXXXXXX`
              atool -x --save-outdir=$TMP "$@"
              DIR="`cat $TMP`"
              [ "$DIR" != "" -a -d "$DIR" ] && cd "$DIR"
              rm $TMP
            }
       If you don't have the mktemp program, you can replace the second line with  (note  however
       that this is not entirely safe)
              TMP="/tmp/atool_outdir.$$"

KNOWN BUGS

       Trying  to extract gzip and other compressed files without the .gz (or .bz2 etc) extension
       won't work:

         aunpack: foo: format not known, identifying using file
         aunpack: foo: format is `gzip'
         gzip: foo: unknown suffix -- ignored

       This last error above is generated by gzip -d foo.
