Top Forums UNIX for Dummies Questions & Answers Reading compressed files during a grep search Post 302436160 by ryan.lee on Friday 9th of July 2010 10:38:11 AM

I think i've tried zgrep in the past, but I can't remember why i didn't use it. I just tried it with my script, but it returns a message saying that it doesn't recognize my options. The message reads: "/usr/bin/zgrep: -iro: option not supported" and "/usr/bin/zgrep: -iroln: option not supported". I tried separating them out (e.g. -i -r -o) and it only returned a message saying the "-r" option was invalid. Does zgrep search recursively?

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
