If you're using bash, you could use the "select" loop, altough then your
script won't work in the regular Bourne shell. The following information
is from "Sams Teach Yourself Shell Programming in 24 Hours".
The basic syntax of select is:
select name in word1 word2 ... wordN
do
list
done
name represents the name of a variable
word1 to wordN represent words seperated by spaces
list represents the set of commands to execute after the user has made a
selection.
The book also gives an example of "select" being used for software
configuration. The actual commands have been omitted:
select COMPONENT in comp1 comp2 comp3 all none
do
case $COMPONENT in
comp1|comp2|comp3) CompConf $COMPONENT ;;
all) CompConf comp1
CompConf comp2
CompConf comp3
;;
none) break ;;
*) echo "ERROR: Invalid selection, $REPLY." ;;
esac
done
Hope this helps.

The script uses a menu interface. Basically, something like "Select what task
to do:", list the tasks, then the user hits a key (or types a value followed
by enter).
I found reference to the "read" command to get a value from the user. But
it's not quite the best fit... It shows a flashing cursor, and control
characters if the user happens to hit a cursor key. Is there a better suited
command/tool for this? Ideally I'd like to label the tasks/options with
letters, and then have the user just tap that letter - no enter key needed.
