Shell Programming and Scripting

Hi,

I have a file with below contents, 3 lines, all are PASS:
cat filetest.log
PASS
PASS
PASS

I would need to check this file to ensure the contents are remain unchanged with only 3 lines and 3 PASS as above, and should return 0 for every check, if any of these content are change then should return 1.

Appreciate of any help given here.

Thanks

Code:

#!/bin/ksh

actual=$(<filetest.log)
expected="PASS
PASS
PASS"

if [[ $actual == $expected ]]
then
    print all fine
    exit 0
else
    print bad bad bad...
    exit 1
fi

Code:

 
grep -v "^PASS$" test && echo "Not fine" || echo "Fine"
