Hi all

I'm trying to evalute the return status of a function without much success. I've put a very basic example below to explain.

check_ok() works fine but when used within an if statement, it always returns true, whether it is true or false. I'm guessing it returns true as the function succeeded, rather than the statement within it.

The check_ok function I am actually using has a lot of code ans is used many times in the script. I have tried various ways using $?/return etc but was hoping someone could explain the correct way to do this?
thanks for any help.


check_ok()
{
ps aux | grep -v grep | grep SOMETHING
}
if [[ check_ok ]]
then
echo OK
fi
