How do I compress or uncompress files?
Infrequently accessed files may be compressed to save disk space.
gzip file Compresses file to file.gz
gunzip file.gz Uncompresses file.gz to file
gtar xzvf file.tar.gz Uncompresses file.tar.gz to the contents of file.tar
compress x y ... Compresses x, y, ... to x.Z, y.Z, ...
uncompress x y ... Uncompresses x.Z, y.Z, ... to x, y, ...
zcat x.Z y.Z ... Prints the compressed file(s) to the terminal
See the UNIX manual pages for the above programs by using the 'man', for example 'man gzip'.
