DESCRIPTION
xzgrep
invokes
grep(1)
on uncompressed contents of files.
The formats of the
files
are determined from the filename suffixes.
Any
file
with a suffix supported by
xz(1),
gzip(1),
bzip2(1),
lzop(1),
zstd(1),
or
lz4(1)
will be decompressed;
all other files are assumed to be uncompressed.
If no
files
are specified or
file
is
-
then standard input is read.
When reading from standard input, only files supported by
xz(1)
are decompressed.
Other files are assumed to be in uncompressed form already.
Most
options
of
grep(1)
are supported.
However, the following options are not supported:
-
-r,
--recursive
-
-R,
--dereference-recursive
-
-d,
--directories=action
-
-Z,
--null
-
-z,
--null-data
-
--include=glob
-
--exclude=glob
-
--exclude-from=file
-
--exclude-dir=glob
xzegrep
is an alias for
xzgrep -E.
xzfgrep
is an alias for
xzgrep -F.
The commands
lzgrep,
lzegrep,
and
lzfgrep
are provided for backward compatibility with LZMA Utils.
They are deprecated and will be removed in a future version.

is set to a no-empty value,
it is used instead of

grep -E,
or
grep -F.
