I would like to make a script that deletes a directory with rmdir after confirming with a password using read to set the variable.

So far I have this:

#!/bin/bash -x
echo "Password:"
read -t 30 S1
    S2='55555'
if [ $S1=$S2 ]; then
    rmdir /home/william/test
else
    echo "fail"
sleep 10
fi

So, I have the -x to try to debug it but every time the script either fails to echo (if I put the password in wrong) or it wont remove the directory needed.

If someone has a modifiable script that I could use or if you could point out the problems with the current script that would be great.

The right way to compare those two strings (S1 and S2) using if is:

if [ "$S1" = "$S2" ]

Do not be stingy in use spaces in this case.
