NAME
xzgrep - search compressed files for a regular expression
SYNOPSIS
xzgrep [
grep_options] [
-e]
pattern [
file...]
xzegrep ...
xzfgrep ...
lzgrep ...
lzegrep ...
lzfgrep ...
DESCRIPTION
xzgrep invokes
grep(1) on
files which may be either uncompressed or
compressed with
xz(1),
lzma(1),
gzip(1),
bzip2(1),
lzop(1), or
zstd(1). All options specified are passed directly to
grep(1).
If no
file is specified, then standard input is decompressed if
necessary and fed to
grep(1). When reading from standard input,
gzip(1),
bzip2(1),
lzop(1), and
zstd(1) compressed files are not
supported.
If
xzgrep is invoked as
xzegrep or
xzfgrep then
grep -E or
grep -F is
used instead of
grep(1). The same applies to names
lzgrep,
lzegrep,
and
lzfgrep, which are provided for backward compatibility with LZMA
Utils.
EXIT STATUS
0 At least one match was found from at least one of the input
files. No errors occurred.
1 No matches were found from any of the input files. No errors
occurred.
>1 One or more errors occurred. It is unknown if matches were
found.
ENVIRONMENT
GREP If the
GREP environment variable is set,
xzgrep uses it
instead of
grep(1),
grep -E, or
grep -F.
