Unix ---> compress/uncompress

The compress and uncompress commands compress a selected file using adaptive Lempel-Ziv coding to help conserve disk space. This technique almost always does a better job than the Huffman coding technique used by the pack/unpack commands. Typing compress edison would create a compressed file called edison.Z which could be resorted to its original condition by typing uncompress edison or uncompress edison.Z.

You may want to check to see if you have gzip installed on your system. It also uses Lempel-Ziv coding but often outperforms compress. Gzip offers additional feature like 32 bit CRC consistency checks.
