compress, uncompress, zcat - compress a file using modified Lempel-Ziv
compress [-cdfv] [file] ...
-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
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
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).
