I would recommend a simpler and more portable solution:

Code:
PATH=$(getconf PATH):$PATH awk …

Should this need to work with the legacy Bourne shell on Solaris 10 and older:

Code:
PATH=`getconf PATH`:$PATH awk …

This should work on all Unix and Unix like OSes.

I've just discovered that my suggestion was flawed by the fact that bash only supports aliases when in interactive mode. You could try my suggestion of testing for nawk etc using the AWK variable as suggested by bakunin.

Just remember that where you would normally invoke awk or nawk in your scripts you use $AWK (or preferably ${AWK}) instead.

Sorry about that.
