.SH NAME
zcmp \- decompress and compare two files byte by byte
.SH SYNOPSIS
.B zcmp
[\fI\,options\/\fR] \fI\,file1 \/\fR[\fI\,file2\/\fR]
.SH DESCRIPTION
Zcmp compares two files ('\-' means standard input), and if they differ,
tells the first byte and line number where they differ. Bytes and lines
are numbered starting with 1. If any given file is compressed, its
decompressed content is used. Compressed files are decompressed on the
fly; no temporary files are created.
zcmp compares two files and, if they differ, writes to standard output the
first byte and line number where they differ. Bytes and lines are numbered
starting with 1. A hyphen '\-' used as a file argument means standard input.
If any file given is compressed, its decompressed content is used. Compressed
files are decompressed on the fly; no temporary files are created.
.PP
The formats supported are bzip2, gzip, lzip and xz.

zcmp compares file1 to file2. The standard input is used only if file1 or
file2 refers to standard input. If file2 is omitted zcmp tries the

the corresponding uncompressed file (the name of file1 with the
extension removed).
.IP
2. If file1 is uncompressed, compares it with the decompressed
\- If file1 is uncompressed, compares it with the decompressed
contents of file1.[lz|bz2|gz|xz] (the first one that is found).
.IP
3. If no suitable file is found, compares file1 with data read from
standard input.
.PP
Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
