Answer / suitable
The cmp command compares two files of any type and writes
the results to the standard output. By default, 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.
diff command find differences between two files

Answer / deepa rajendran
The cmp command compares two files, and (without options)
reports the location of the first
difference between them. It can deal with both binary and
ASCII file comparisons. It does a
byte-by-byte comparison.
But in diff compares two files, directories, etc, and
reports all differences between the two. It
deals only with ASCII files. It’s output format is designed
to report the changes necessary to convert
the first file into the second.

Answer / s.sunny
cmp compares the files byte by byte and in first occurence
it shows if any unmatch character will found in error which
contains char no./column no. and line no.
diff is command which tells how to make the files identical.
the o/p is very confussing way. easy way that diff compares
files line by line.
Example:
test1: test2:
1.test! 1.test!
2.a common line. 2.a almost common line.
3.really common line. 3.really common line.
4.one more common line. 4.really not common line.
5.only here. 5.one further line.
6.one more common line.
o/p:
2c2
< A common line.
---
> A almost common line.
3a4,5
> Really not common line.
> One further line.
5d6
< Only here.
imp:
first file (<)
second file (>)
dashed line (-)--> separate o/p from two files.
imp:
c : replace line
d : delete line
a : add line
imp:
1. line 2 differ both files.(which present symbol 'c')
2. line 4 & 5 of 2nd file add in 1st file after 3 line.
(which present symbol 'a')
3. line 5 of file 1 no need to exchange with file 2 for
making 2 files identical, so we delete line 5 from file 1.
(5d6--> line 5 delete from file 1 and that 6 no. shows that
total line 6 in both files means ending line no.)
that's it friends. read carefully....understand each and
every line...u can easily find the meaning of diff and
working...
take care.........
