NAME NAME
zcmp - decompress and compare two files byte by byte zcmp - decompress and compare two files byte by byte
SYNOPSIS SYNOPSIS
zcmp [options] file1 [file2] zcmp [options] file1 [file2]
DESCRIPTION DESCRIPTION
Zcmp compares two files ('-' means standard input), and if they differ zcmp compares two files and, if they differ, writes to standard output
, tells the first byte and line the first byte and line number
number where they differ. Bytes and lines are numbered starting with 1. I where they differ. Bytes and lines are numbered starting with 1. A hyphen
f any given file is compressed, '-' used as a file argument
its decompressed content is used. Compressed files are decompressed on means standard input. If any file given is compressed, its decompres

created. files are decompressed on the fly; no temporary files are created.
The formats supported are bzip2, gzip, lzip and xz. The formats supported are bzip2, gzip, lzip, and xz.
Zcmp compares file1 to file2. If file2 is omitted zcmp tries the followin zcmp compares file1 to file2. The standard input is used only if file1
g: or file2 refers to standard
input. If file2 is omitted zcmp tries the following:
1. If file1 is compressed, compares its decompressed contents with the corresponding uncompressed - If file1 is compressed, compares its decompressed contents with the corresponding uncompressed
file (the name of file1 with the extension removed). file (the name of file1 with the extension removed).
2. If file1 is uncompressed, compares it with the decompressed c ontents of file1.[lz|bz2|gz|xz] - If file1 is uncompressed, compares it with the decompressed con tents of file1.[lz|bz2|gz|xz]
(the first one that is found). (the first one that is found).
3. If no suitable file is found, compares file1 with data read fro
m standard input.
Exit status is 0 if inputs are identical, 1 if different, 2 if trouble. Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
