gzip, compress (p.111)

• Usage: gzip [filename]: compress specified filename

gunzip [filename]: uncompress specified filename

• Examples:

gzip file1 creates file1.gz

gunzip <file2.gz | more leaves file2.gz intact

cat file3 | gzip > newFile.gz leaves file3 intact

• compress behaves like gzip, using a different (less efficient) compression algorithm is used (resulting files have .Z extension).

• Similarly, uncompress behaves like gunzip
