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 speci‐
fied 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 pro‐
gram to be invoked.

EXIT CODE
2 – An option that is not supported was specified.
