NAME
zgrep, zegrep, zfgrep — print lines matching a pattern in gzip-compressed files
SYNOPSIS
zgrep
[grep-flags] [--] pattern [files ...]
zegrep
[grep-flags] [--] pattern [file ...]
zfgrep
[grep-flags] [--] pattern [file ...]
DESCRIPTION
zgrep runs
grep(1) on
files or stdin, if no
files argument is given, after decompressing them with
zcat(1).
The
grep-flags and
pattern arguments are passed on to
grep(1). If an
-e flag is found in the
grep-flags,
zgrep will not look for a
pattern argument.
zegrep calls
egrep(1), while
zfgrep calls
fgrep(1).
EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
