- COMPRESS(1) Minix Programmer's Manual COMPRESS(1)
- NAME
- compress, uncompress, zcat - compress a file using modified Lempel-Ziv
- coding
- SYNOPSIS
- compress [-cdfv] [file] ...
- OPTIONS
- -c Put output on stdout instead of on file.Z
- -d Decompress instead of compress
- -f Force output even if there is no saving
- -v Verbose mode
- EXAMPLES
- compress <infile >outfile
- # Compress 1 file
- compress x y z # Compress 3 files to x.Z, y.Z, and z.Z
- compress -d file.Z # Decompress file.Z to file
- DESCRIPTION
- The listed files (or stdin, if none are given) are compressed using the
- Ziv-Lempel algorithm. If the output is smaller than the input, the
- output is put on file.Z or stdout if no files are listed. If compress is
- linked to uncompress, the latter is the same as giving the -d flag.
- Similarly, a link to zcat decompresses to stdout. The MINIX version of
- compress uses 13-bit compression. This means that when compressing files
- on other systems for transmission to MINIX, be sure that only 13-bit
- compression is used. On many systems, the default is 16-bit (too big).

- tar(1).
