NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed, xz'ed, lzma'ed, zstd'ed, bzip2'ed or
gzipped files. All options specified are passed directly to grep. If
no file is specified, then the standard input is decompressed if neces-
sary 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 STATUS
Exit status is 0 for a match, 1 for no matches, and 2 if trouble.
BUGS
The following grep options are not supported: --dereference-recursive
(-R), --directories (-d), --exclude, --exclude-from, --exclude-dir,
--include, --null (-Z), --null-data (-z), and --recursive (-r).
