compress -- Command Compress a file compress [ -dfvc ] [ -bnum ] [ file ... ] compress compresses a file using the Lempel-Ziv algorithm. With text files and archives, it often can achieve 50% rate of compression. If one or more files are specified on the command, compress compresses them and appends the suffix .Z onto the end of each compressed file's name. If no file is specified on the command line, compress compresses text from the standard input and writes the compressed text to the standard output. compress recognizes the following options: -b The ``bits'' option. compress uses the compression level set via the num argument. Previous releases of compress would only allow values of num up to 12, with 12 being the default value if the -b option was not specified. The version of compress introduced with COHERENT version 3.1 handles values up to 16, with 12 being the default. -c Send output to stdout. -d Decompress rather than compress. -f Force an output file to be generated even if no space is saved by compression. -v Verbose mode: force compress to write statistics about its performance. If you wish to ensure backwards compatibility with previous releases of COHERENT, do not use compress with a num value greater than 12. See Also commands, compression, gzip, ram, uncompress, zcat
