+.SH NAME
+xzcmp, xzdiff, lzcmp, lzdiff \- compare compressed files
+.SH SYNOPSIS
+.B xzcmp
+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B xzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.br
+.B lzcmp
+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B lzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.SH DESCRIPTION
+.B xzcmp
+and
+.B xzdiff
+invoke
+.BR cmp (1)
+or
+.BR diff (1)
+on files compressed with
+.BR xz (1),
+.BR lzma (1),
+.BR gzip (1),
+.BR bzip2 (1),
+.BR lzop (1),
+or
+.BR zstd (1).
+All options specified are passed directly to
+.BR cmp (1)
+or
+.BR diff (1).
+If only one file is specified, then the files compared are
+.I file1
+(which must have a suffix of a supported compression format) and
+.I file1
+from which the compression format suffix has been stripped.
+If two files are specified,
+then they are uncompressed if necessary and fed to
+.BR cmp (1)
+or
+.BR diff (1).
+The exit status from
+.BR cmp (1)
+or
+.BR diff (1)
+is preserved unless a decompression error occurs; then exit status is 2.
+.PP
+The names
+.B lzcmp
+and
+.B lzdiff
+are provided for backward compatibility with LZMA Utils.
+.SH "SEE ALSO"
+.BR cmp (1),
+.BR diff (1),
+.BR xz (1),
+.BR gzip (1),
+.BR bzip2 (1),
+.BR lzop (1),
+.BR zstd (1),
+.BR zdiff (1)
+.SH BUGS
+Messages from the
+.BR cmp (1)
+or
+.BR diff (1)
+programs refer to temporary filenames instead of those specified.

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