Simple Script "space" problem

[KrazyPenguin]

Here is a simple menu script but how do I get rid of the space
between Start and Backup?
Obviously I am getting three options listed instead of two:
Start
Backup
Quit

OPTIONS="Start Backup Quit"
select opt in $OPTIONS; do
if [ "$opt" = "Start Backup" ]; then
echo "start backup"
exit
elif [ "$opt" = "Quit" ]; then
echo done
else
clear
echo bad option
fi
done

But I want Start Backup to be one option.
I am new to this and learning a little here and a little there.
I search google but couldn't find the answer.
Thanks.

Did you try a backslash before the space? That's one common way to enter spaces - the backslash "escapes" the space.

Just one blind man trying to lead another here. :)

The easy way would be to change the space to either - or _


OPTIONS="Start-Backup Quit"

select opt in $OPTIONS; do
if [ "$opt" = "Start-Backup" ]; then
echo "start backup"
exit
elif [ "$opt" = "Quit" ]; then
echo done
exit
else
clear
echo bad option
fi
done

The harder way:

If you don't feed the in list option to select, it takes its options from the command line arguments.
It just so happens that set -- "Start Backup" Quit will set $1 to Start Backup and $2 to Quit

Therefore:

set -- "Start Backup" Quit

select opt; do
if [ "$opt" = "Start Backup" ]; then
echo "start backup"
exit
elif [ "$opt" = "Quit" ]; then
echo done
exit
fi
done
will get you an option with a space in it. Also remember that if you set PS3= a string, the string will follow your menu as a prompt.

PS3="Begin backup now: "
set -- "Start Backup" "No, Quit"
select opt; do
if [ "$opt" = "Start Backup" ]; then
echo "Starting backup"
exit
elif [ "$opt" = "No, Quit" ]; then
echo done
exit
fi
done

gets me:


1) Start Backup
2) No, Quit
Begin backup now: 1
Starting backup

Hope this helps!
