array=('org.battery.plist' 'org.disk.plist' 'org.memory.plist'); echo "1) org.battery.plist" echo "2) org.disk.plist" echo "3) org.memory.plist" echo "Enter selection(s) to load, separated by commas: " read var sudo launchctl load -w ${array[$var]} Am I on the right track? I'm a little stuck. Can someone help?
If user inputs 1, 2, I expect the script to perform this below -
sudo launchctl load -w org.disk.plist sudo launchctl load -w org.memory.plist Try this,
IFS="," for i in $var do sudo launchctl load -w ${array[$i - 1]} done You will also need to check whether the input is out of array bounds and throw and error.
There is a buildin in bash for such selects, surprisingly, called 'select':
select entry in ${array[@]}; do sudo launchctl load -w $entry done Try help select.
help select should work, as it's a shell built-in. man select will probably give you the manpage for the (unrelated) syscall.This is better:
array=('org.battery.plist' 'org.disk.plist' 'org.memory.plist'); for (( i=0;i<"${#array[@]}";i++ )) ; do let n=i+1 printf '%d) %s\n' $n "${array[$i]}" done IFS=, read -r -p 'Enter selection(s) to load, separated by commas: ' -a selections for selection in "${selections[@]}" ; do let selection=selection-1 sudo launchctl load -w "${array[$selection]}" done 
select ... in ...statement inbash. typehelp selectin the terminal for help.
