.TH ZDIFF "1" "December 2009" "Zdiff (zutils) 0.8-rc1" "User Commands"
.SH NAME
Zdiff \- compare compressed files
.SH SYNOPSIS
.B zdiff
[\fIOPTIONS\fR] [\fIDIFF_OPTIONS\fR] \fIFILE1 \fR[\fIFILE2\fR]
.SH DESCRIPTION
Zdiff \- Diff/cmp wrapper for compressed files.
.PP
Zdiff is a wrapper script around the diff and cmp commands that allows
transparent comparison of any combination of compressed and
non\-compressed files. If any given file is compressed, its uncompressed
content is used. The supported compressors are bzip2, gzip, lzip and xz.
.PP
Zcmp is a shortcut for "zdiff \fB\-\-cmp\fR"
.PP
Compares FILE1 to FILE2. If FILE2 is omitted and FILE1 is compressed,
compares FILE1 to the file with the corresponding decompressed file
name (removes the extension from FILE1). If FILE2 is omitted and FILE1
is not compressed, compares FILE1 to the uncompressed contents of
FILE1.[bz2|gz|lz|xz] (the first one that is found).
DIFF_OPTIONS are passed directly to diff or cmp.
The exit status from diff or cmp is preserved.
