sh in Linux is a link to bash, that's not a problem.

There's no reason why this should not work. I suggest you remove the lines (possible control character (most likely ^M)) and paste them again from some post in this thread.

Code:
[root@admin2 tmp]# ./s1
: integer expression expected
[root@admin2 tmp]# cat -v s1
value=$(sed -n "/^LoggingLevel=/{s/.*=//;p;q;}" file)

if [ $value -gt 2^M ]; then
  echo more than 2
fi

no Sir, still the same error

i even typed the statement to avoid any copy paste errors

still the same :integer expression expected error

Then, I suggest your input file has the ^M character.

Please post the output of cat -v from both your script and the input file.

Thanks a ton for catching that. the input file did have ^M. I deleted the file and recreated it and the IF statement works fine. Thanks again for your time.

Great!

Hindsight's a wonderful thing, but if I'd been more awake, we could have solved this an hour ago Smilie
