scripts and case statement

[Jeffrey W. Stewart]

I am trying to write a script to make the job of copying files a much easier task. Here is my attempt at the script. I would like the script to repeat, and stop when a command like "99" is entered.

#!/bin/sh
# An example with the case statement
# Reads a command from the user and processes it
echo "Enter your command (e.g. 724778:801)"
read command
case "$command" in
724778-801)
cp /hp3070/qm/pbq/$command/events A04940.txt
;;
724778:803)
cp /hp3070/qm/pbq/$command/events A04278.txt
;;
724782-801)
cp /hp3070/qm/pbq/$command/events A04615.txt
;;
99)
echo "exit"
?? (command to exit
;;
esac

It seems like you're looking for the command to make the script exit? It's "exit", as in:

"99" )
echo exiting...
exit 0;;

Hi


command=ok
while [ "$command" != "99" ]
do

your script

done



The do loop will repeat as long as command is not 99

Use exit for that. By normal successful exit use exit 0 at the end of every shell script. To differentiate use exit 1 or some int. It will be good as like system commands.

And more if you are giving an unknown option then your script will not handle that one.

So use as like

*)
echo "Unknown options.. and your set of options"
exit 2

It will be very good on your script.

Hi,

The following usually works fine:

while true; do
echo "Enter your command (e.g. 724778:801)"
read command
case $command in
...
...
99) break ;;
*) echo "Input error:<$command>" ;;
esac
done
