unix script menu not working

[eb222]

Im using below script on sun and it just comes back to the command prompt without running any env variables. the env variables exist in the correct directories and they run manually no problem.


#!/bin/sh
MAIL=/usr/mail/${LOGNAME:?}

# Set up the shell environment:
#set -u
#trap "echo 'logout'" 0
stty erase ^H

# Set up the shell variables:
EDITOR=vi
export EDITOR

TERM=vt220 ; export TERM
ANS='X';
while [ "$ANS" != "EXIT" ]
do
tput clear
clear
#echo " `date`"
#echo
echo " [SITE] Development Environment"
echo
echo " e-Business Suite"

if [ "$loop" = "Y" ]; then
case $ANS in

You seem to know about the . or "source" operator. Trouble is, you need to source this menu also, otherwise all env vars will be set in the menu's subshell end not in your login shell.

But then in option 9, change to 'ANS=EXIT' instead of 'exit', or you'll get logged out after choosing 9.

You might also try to program this menu as a shell function, then it should also work, again change the 'exit' in option 9 to 'return'...


HTH,
