dtrx - Intelligent archive extraction
=====================================
Introduction
------------
dtrx extracts archives in a number of different formats; it currently
supports tar, zip, cpio, rpm, deb, gem, 7z, cab, and rar files. It can
also decompress files compressed with gzip, bzip2, lzma, 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.
--one, --one-entry
Normally, if an archive only contains one file or directory with a name
that doesn't match the archive's, dtrx will ask you how to handle it.
With this option, you can specify ahead of time what should happen.
Possible values are:
inside
Extract the file/directory inside another directory named after the
archive. This is the default.
rename
Extract the file/directory in the current directory, and then rename
it to match the name of the archive.
here
Extract the file/directory in the current directory.
-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 all 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, conservative
defaults.
-l, -t, --list, --table
Don't extract the archives; just list their contents on standard output.
-m, --metadata
Extract the metadata from .deb and .gem archives, instead of their normal
contents.
-q, --quiet
Suppress warning messages. Listing this option twice will cause dtrx to
be silent.
-v, --verbose
Show the files that are being extracted. Listing this option twice will
cause dtrx to print debugging information.
--help
Display basic help.
--version
Display dtrx's version, copyright, and license information.
