SYNOPSIS

9       zgrep [ grep_options ] [ -e ] pattern filename...
10

DESCRIPTION

12       Zgrep  invokes grep on compressed or gzipped files.  All options speci‐
13       fied are passed directly to grep.  If no file is  specified,  then  the
14       standard input is decompressed if necessary and fed to grep.  Otherwise
15       the given files are uncompressed if necessary and fed to grep.
16
17       If the GREP environment variable is set, zgrep uses it as the grep pro‐
18       gram to be invoked.

EXIT STATUS

21       Exit status is 0 for a match, 1 for no matches, and 2 if trouble.
