XZGREP(1) XZ Utils XZGREP(1)
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 neces-
sary 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.
SEE ALSO
grep(1), xz(1), gzip(1), bzip2(1), lzop(1), zstd(1), zgrep(1)
