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. All 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.
