nawk—pattern scanning and processing language
nawk [ –F re ] [ –v var=value ] [ 'prog' ] [ filename … nawk [ –F re ] [ –v var=value ] [ –f progfile ][ filename …]
nawk scans each input filename for lines that match any of a set of patterns. The command string must be enclosed in single quotes (') to protect it from the shell. awk programs consist of a set of pattern/action statements used to filter specific information from a file, pipe, or stdin. Linux uses gawk. ( See "awk" on page673.)
