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

LEARN ABOUT MINIX

partitio

PARTITION(8)						      System Manager's Manual						      PARTITION(8)

NAME

       partition - make a partition table

SYNOPSIS

       partition [-mf] device [type:]size[+*] ...

DESCRIPTION

       Partition  makes  a partition table on device using the types and sizes given.  It may be used in combination with repartition(8) for auto-
       matic installation of Minix.

       You may give up to four type:size[+*] specifications for the partitions.  You may also specify holes before, between, and after the  parti-
       tions.  A hole differs from a partition specification by not having a type.

       The first hole is by default 1 sector to make space for the primary bootstrap and the partition table.  The other holes are 0.

       The  type  field is the type of the partitition in hexadecimal.	The size field is the partition's size in sectors.  The + or * may option-
       ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active.

       Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1.  Some operating systems care about  this.
       Minix and MS-DOS do not.

OPTIONS

       -m     Minix only, no need to pad partitions.  This is the default for subpartition tables.

       -f     Force making a partition table even if the device is too small.

EXAMPLE

       partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+

       Partitions  disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end
       of the disk.  (06:0+ would have been ok too, it's just a sanity check.)

SEE ALSO

       hd(4), part(8), repartition(8).
