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), 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).
