.Sh NAME
|
|
.Nm cmp
|
|
.Nd compare two files
|
|
.Sh SYNOPSIS
|
|
.Nm cmp
|
|
.Op Fl l | Fl s
|
|
.Ar file1 file2
|
|
.Op Ar skip1 Op Ar skip2
|
|
.Sh DESCRIPTION
|
|
The cmp utility compares two files of any type and writes the results
|
|
to the standard output.
|
|
By default,
|
|
.Nm
|
|
is silent if the files are the same; if they differ, the byte
|
|
and line number at which the first difference occurred is reported.
|
|
.Pp
|
|
Bytes and lines are numbered beginning with one.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width flag
|
|
.It Fl l
|
|
Print the byte number (decimal) and the differing
|
|
byte values (octal) for each difference.
|
|
.It Fl s
|
|
Print nothing for differing files; return exit
|
|
status only.
|
|
.El
|
|
.Pp
|
|
The optional arguments
|
|
.Ar skip1
|
|
and
|
|
.Ar skip2
|
|
are the byte offsets from the beginning of
|
|
.Ar file1
|
|
and
|
|
.Ar 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
|
|
.Nm cmp
|
|
utility exits with one of the following values:
|
|
.Bl -tag -width 4n
|
|
.It 0
|
|
The files are identical.
|
|
.It 1
|
|
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
|
|
.Fl s
|
|
option has not been specified,
|
|
.Nm cmp
|
|
writes to standard output that EOF was reached in the shorter
|
|
file (before any differences were found).
|
|
.It >1
|
|
An error occurred.
|
|
.El
|
|

.Sh STANDARDS
|
|
The
|
|
.Nm cmp
|
|
utility is expected to be
|
|
.St -p1003.2
|
|
compatible.
