What does ENDOFMENU do?
- by Raymond
I have been given an example program, I am wondering what exactly the <<ENDOFMENU and ENDOFMENU does, won't it work the same if you leave it out and just use the while loop?
#!/bin/sh
echo "Menu test program...";
stop=0;
while test $stop -eq 0; do
cat<<ENDOFMENU
1: print the date
2,3 : print the current working directory
4: exit
ENDOFMENU
echo; echo -e "your choice?\c"
read reply
echo
case $reply in
"1")
date
;;
"2"|"3")
pwd
;;
"4")
stop=1
;;
*)
echo illegal choice
esac
done
