SYNOPSIS
xzgrep

DESCRIPTION
xzgrep
invokes
grep(1)
on
files
which may be either uncompressed or compressed with
xz(1),
lzma(1),
gzip(1),
bzip2(1),
or
lzop(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),
and
lzop(1)
compressed files are not supported.
If
xzgrep
is invoked as
xzegrep
or
xzfgrep
then
egrep(1)
or
fgrep(1)
is used instead of
grep(1).
The same applies to names
lzgrep,
lzegrep,
and
lzfgrep,
which are provided for backward compatibility with LZMA Utils.
ENVIRONMENT
- GREP
-
If the
GREP
environment variable is set,
xzgrep
uses it instead of
grep(1),
egrep(1),
or
fgrep(1).
