ZGREP(1)                                                              ZGREP(1)



NAME
       zgrep - search possibly compressed files for a regular expression

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

DESCRIPTION
       Zgrep  is  used to invoke the grep on compress'ed or gzip'ed files. All
       options specified are passed directly to grep.  If no  file(1,n)  is  speci-
       fied,  then  the standard input is decompressed if(3,n) necessary and fed to
       grep.  Otherwise the given files are uncompressed if(3,n) necessary and  fed
       to grep.

       If  zgrep  is  invoked  as zegrep or zfgrep then egrep or fgrep is used
       instead of grep.  If the GREP environment variable is set(7,n,1 builtins),  zgrep  uses
       it as the grep program to be invoked. For example:

           for sh:  GREP=fgrep  zgrep string(3,n) files
           for csh: (setenv GREP fgrep; zgrep string(3,n) files)
