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  uncom‐
       pressed 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.
