.th PRESS I 8/12/77 .sh NAME press - compress a file .sh SYNOPSIS press [ - ] [ infile [ outfile ] ] .sh DESCRIPTION Compresses input file by replacing strings of 4 or more identical characters by a single character and a count. The '-' option expands a previously compressed file. Usable as a filter. Generally useless with UNIX text files, but saves space with "fixed-record-length" files (e.g. imported from Interdata) containing lots of blanks. .sh AUTHOR R Miller .br University of Wollongong
