Compare 2 Files

Shell Programming and Scripting
1

Hi

requirement : I have file a and b. need to compare both are matching.

FIle a
----

/ct/mr/test/bin/b
/ct/mr/test/bin/CheckEmpty
/ct/mr/test/bin/ChkFile2

File b
---

/ct/mr/test/bin/CheckEmpty
/ct/mr/test/bin/ChkFile2
/ct/mr/test/bin/b

Eventhough content is same it is in different order.

The shell script
-------------

#!/usr/bin/sh

if diff  a b  > /dev/null
then
    echo "Files are the same"
    else
    echo "Files are different"
fi

this gives output files are different.

Question : how to make same order and compare 2 files.
Could any one help on this

Thanks in advance
Hari

Sort the files and compare:

 diff <(sort a) <(sort b)

Guru.

No point in using diff if you're going to throw away its output. Just use cmp, after sorting as guruprasadpr suggests.
