CMP(1) (Essential Utilities) CMP(1)
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.
