compare two files
From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.
With the diffutil package (with the extra set), see cmp(1) instead.
NAME
cmp - compare two files
SYNOPSIS
cmp [ -l ] [ -s ] file1 file2
DESCRIPTION
The two files are compared. (If file1 is -, the standard input is used.) Under default options, cmp makes no comment if the files are the same; if they differ, it announces the byte and line number at which the difference occurred. If one file is an initial subsequence of the other, that fact is noted. Options:
-l Print the byte number (decimal) and the differing bytes (octal) for each difference.
-s Print nothing for differing files; return codes only.
SEE ALSO
comm(1), diff(1).
DIAGNOSTICS
Exit code 0 is returned for identical files, 1 for different files, and 2 for an inaccessible or missing argument.
