dxcompress is a compression and decompression utility supporting multiple compression algorithms. It currently supports the Lempel-Ziv-Welch (LZW) algorithm, the DEFLATE (gzip) algorithm and the XZ compression format.
A single compress binary provides all the functionality. The scripts
uncompress and zcat are also provided as synonyms for compress -d and
compress -cd. Additional scripts gzip, gunzip, xz, unxz, and xzcat
can also be installed for compatibility with other compression utilities.
The compress utility should support all options that are recognized by most
compression utilities.
The compress, uncompress, and zcat utilities conform to the POSIX.1-2008
standard. All additional functionality required by the upcoming POSIX.1-202x
standard is also provided.
dxcompress uses an autoconf-generated configure script to configure the build.
When building from a git checkout, the configure script first needs to be
regenerated by running the autogen.sh script. The release tarballs already
contain the configure script.
The configure script accepts the usual options like --prefix to customize the
installation. Run configure --help for more information. Additionally the
--enable-wrapper=WRAPPERS option is also recogonized and causes additonal
wrapper scripts to be installed that behave like the compression and
decompression utilities for specific compression algorithms. WRAPPERS is a
comma-separated list of utilities. Valid utilities are gzip (installing gzip
and gunzip) and xz (installing xz, unxz, and xzcat).
After running the configure script, dxcompress can be built with make and
installed with make install. A testsuite can be run with make check.
