bash script array

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

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

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.

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.
