If you want a 1-liner, IPT=`which iptables` would work for tcsh, & I 
*think* there is something similar in bash (hmmmm .... just checked & 
'which' is an executable, used to be csh-specific, back in the day 
....). If you look through the startup scripts in /etc/init.d/, you 
might get some ideas about how to proceed, they often do that sort of 
thing in there .... Your 2nd bit of coding above should work well & be 
quite portable if necessary.
