Shell Scripting awk Problem
I'm limited in my skills related to *nix and I'm even more limited in my skills related to shell scripting and the use of awk. I have what should be a relatively simple shell script that looks in the /etc/fstab to see if a particular partition exists on the Linux system. The intention of this part of the script is to determine whether a /tmp partition exists on the system. If such a partition does exist, then no output would be returned. If such a partition does not exist, then three lines of text would be echoed to the screen and the script would terminate right there. So, I need to test both a positive (so that the lines of text get echoed to the screen, and a negative (so that nothing gets returned to the screen). In order to test a positive, I have my command looking for a /temp entry in /etc/fstab instead of a /tmp entry (since the system I'm testing does have a /tmp partition). Below is my code. I get no errors when I run it but I'm never able to get a positive, so I know my code is not working. Can someone tell me what is wrong with my code. Please, I do not won't suggestions about other ways to try to get the same information. I just want to know what to correct in my code to get it to work the way I need it to work.

Code:
#!/bin/bash
/bin/awk if ( grep "[[:space:]]/temp[[:space:]]" /etc/fstab )= "" then
    echo "The RHEL security benchmarks require that there be a /tmp file partition."
    echo "Since this system doesn't have one, you will need to rebuild the system,"
    echo "creating a /tmp partition.
    break
fi
