Compress one or more files by using Lempel-Ziv compression.
compress [-cdrvV] files
-c writes the compressed file to the standard output and retains the original file.
-d decompresses the file.
-r recursively compresses files in all subdirectories.
-v displays a message as each file is compressed.
-V prints the version number and exits.
The compress command compresses each specified file and replaces the original with the compressed version (with a .Z suffix appended to the name). You can decom-press the file with the compress -d command or the uncompress command.
