NAME
cmp — compare two files
SYNOPSIS
cmp [-blsx] file1 file2 [seek1[seek2]]
DESCRIPTION
cmp
cmp compares two files. If either file name is -, cmp reads the standard input for that file. By
default, cmp begins the comparison with the first byte of each file. If you specify seek1 and/or
seek2, cmp uses it as a byte offset into file1 or file2 (respectively), and comparison begins at that
offset instead of at the beginning of the files. The comparison continues (one byte at a time) until a
difference is found, at which point the comparison ends and cmp displays the byte and line number
where the difference occurred. cmp numbers bytes and lines beginning with 1.
Options
-b
-l
-s
-x
EXAMPLE
compares single blocks at a time. Normally, cmp reads large buffers of data into memory for
comparison.
causes the comparison and display to continue to the end. cmp displays the byte number (in
decimal) and the differing bytes (in octal) for each difference found. cmp attempts no
resynchronization.
suppresses output and returns a non-zero status if the files differ.
displays the differing bytes shown by the -l option in hex.
