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?

I was wondering if there's a way to search within a file that's been compressed. i.e. if file a is inside file a.zip or a.gz, is there a a command that will retrieve the string of data I'm looking for in file a, and list which compressed file it found it in?
Please help!
Thanks. (8 Replies)

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.
