.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 SEE ALSO
|
||||
.BR diff(1),
|
||||
.BR diff3(1)
|
||||
.SH HISTORY
|
||||
The
|
||||
.BR cmp
|
||||
command for GNO/ME v2.0.6 is based on FreeBSD source code.
