dtrx - Intelligent archive extraction
=====================================

Introduction
------------

dtrx extracts archives in a number of different formats; it currently
supports tar, zip, cpio, rpm, and deb.  It can also decompress files
compressed with gzip, bzip2, or compress.

In addition to providing one command to handle many different archive
types, dtrx also aids the user by extracting contents consistently.  By
default, everything will be written to a dedicated directory that's named
after the archive.  dtrx will also change the permissions to ensure that the
owner can read and write all those files.

Running dtrx
------------

To run dtrx, simply call it with the archive(s) you wish to extract as
arguments.  For example::

   dtrx coreutils-5.*.tar.gz

dtrx supports a number of options to mandate specific behavior:

-r, --recursive
   With this option, dtrx will search inside the archives you specify to see
   if any of the contents are themselves archives, and extract those as
   well.

-o, --overwrite
   Normally, dtrx will avoid extracting into a directory that already exists,
   and instead try to find an alternative name to use.  If this option is
   listed, dtrx will use the default directory name no matter what.

-f, --flat
   Extract archive contents into the current directory, instead of their
   own dedicated directory.  This is handy if you have multiple archive
   files which all need to be extracted into the same directory structure.
   Note that existing files may be overwritten with this option.

-n, --noninteractive
   dtrx will normally ask the user how to handle certain corner cases, such
   as how to handle an archive that only contains one file.  This option
   suppresses those questions; dtrx will instead use sane defaults.

-l, -t, --list, --table
   Don't extract the archives; just list their contents on standard output.

-q, --quiet
   Suppress warning messages.  Listing this option twice will cause the
   dtrx to be silent if at all possible.

-v, --verbose
   Print more information about x's behavior.  You can list this option up
   to three times for more information.

--help
   Display basic help.

--version
   Display x's version, copyright, and license information.
