What is the 'awk' for? That doesn't look like awk code. (awk is its own programming language.)

You do not need to check if grep's output is blank to see if it found anything. It returns a success or failure code like any other utility. You can plug it into if directly, and invert with ! if needed.

'break' only makes sense in a loop. If you want to exit, 'exit' is what you want, 'exit 1' to exit with error particularly.

Your code looks for /temp, but your warning demands /tmp. Assuming /tmp is what you really want.

You need a return, or ; , between your if statement and the then.

Warning messages should go to standard error.

Code:
if ! grep -q "/tmp" /etc/fstab
then
    echo "The RHEL security benchmarks require that there be a /tmp file partition." >&2
    echo "Since this system doesn't have one, you will need to rebuild the system," >&2
    echo "creating a /tmp partition." >&2
    exit 1
fi

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
