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.

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
