ANYCOMPRESS

NAME

anycompress − use any CompLearn module data compressor to compress a file

SYNOPSIS

anycompress [-L] [ -c compressor ] [ infile ] [ outfile ]

DESCRIPTION

anycompress is a simple and powerful generic compression tool. By default, it reads an input file from standard input. If a command argument is given it will use that as input instead. It produces an output file (or writes to stdout if reading from stdin) by adding an extension to the end of the input filename. The user may optionally specify an output filename instead. The compressor to use may be specified using the complearn.conf(5) configuration file or the -c command line option as described below.

OPTIONS

−c, −−compressor=compressor

use and set compressor to use

−L, −−list

list available builtin compressors as well as available compression modules. Modules are loaded from the modules subdirectory of /usr/lib/complearn. −h, −−help show help options and exit

EXAMPLES

To gzip a text file to produce a file called readme.txt.gz:
anycompress -c gzip readme.txt
To compute the SHA2 (SHA256) checksum of a file (assuming you have the

complearn cryptographic compression modules installed): anycompress -c sha2 < /bin/ls To do the same with MD5: anycompress -c md5 < /bin/ls
