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

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
