.SH NAME
|
|
.BR cmp
|
|
\- compare two files
|
|
.SH SYNOPSIS
|
|
.BR cmp " [" -l " | " -s "] ["
|
|
.BR -r
|
|
]
|
|
.IR file1
|
|
.IR file2
|
|
[
|
|
.IR skip1
|
|
[
|
|
.IR skip2
|
|
] ]
|
|
.SH DESCRIPTION
|
|
The
|
|
.BR cmp
|
|
utility compares two files of any type and writes the results
|
|
to the standard output.
|
|
By default,
|
|
.BR cmp
|
|
is silent if the files are the same; if they differ, the byte
|
|
and line number at which the first difference occurred is reported.
|
|
Also by default,
|
|
.BR cmp
|
|
also considers the resource forks of the files, and will make note
|
|
if only one of the files has a resource fork.
|
|
.PP
|
|
Bytes and lines are numbered beginning with one.
|
|
.PP
|
|
The following options are available:
|
|
.IP \fB-l\fR
|
|
Print the byte number (decimal) and the differing
|
|
byte values (octal) for each difference.
|
|
.IP \fB-s\fR
|
|
Print nothing for differing files; return exit
|
|
status only.
|
|
.IP \fB-r\fR
|
|
Ignore resource forks when comparing.
|
|
.PP
|
|
The optional arguments
|
|
.IR skip1
|
|
and
|
|
.IR skip2
|
|
are the byte offsets from the beginning of
|
|
.IR file1
|
|
and
|
|
.IR file2 ,
|
|
respectively, where the comparison will begin.
|
|
The offset is decimal by default, but may be expressed as an hexadecimal
|
|
or octal value by preceding it with a leading ``0x'' or ``0''.
|
|
.PP
|
|
The
|
|
.BR cmp
|
|
utility exits with one of the following values:
|
|
.IP \fB0\fR
|
|
The files are identical.
|
|
.IP \fB1\fR
|
|
The files are different; this includes the case
|
|
where one file is identical to the first part of
|
|
the other.
|
|
In the latter case, if the
|
|
.IR -s
|
|
option has not been specified,
|
|
.BR cmp
|
|
writes to standard output that EOF was reached in the shorter
|
|
file (before any differences were found).
|
|
.IP \fB>1\fR
|
|
An error occurred.
|

.SH HISTORY
|
|
The
|
|
.BR cmp
|
|
command for GNO/ME v2.0.6 is based on FreeBSD source code.
