Bash: exit in script doesn't close terminal

Question

I'm working on a script to run on terminal like this one

#!/bin/bash
COUNTER=0
         while [  $COUNTER -lt 10 ]; do
             echo The counter is $COUNTER
             yoooooooo
             sleep 2
             let COUNTER=COUNTER+1 
         done

exit

But once the counter reaches 9 and the while cycle stops, the terminal wont close with the command "exit".

Here's the output

pi@raspberrypi:~/Desktop $ ./sxdd
The counter is 0
./sxdd: line 7: yoooooooo: command not found
The counter is 1
./sxdd: line 7: yoooooooo: command not found
The counter is 2
./sxdd: line 7: yoooooooo: command not found
The counter is 3
./sxdd: line 7: yoooooooo: command not found
The counter is 4
./sxdd: line 7: yoooooooo: command not found
The counter is 5
./sxdd: line 7: yoooooooo: command not found
The counter is 6
./sxdd: line 7: yoooooooo: command not found
The counter is 7
./sxdd: line 7: yoooooooo: command not found
The counter is 8
./sxdd: line 7: yoooooooo: command not found
The counter is 9
./sxdd: line 7: yoooooooo: command not found
pi@raspberrypi:~/Desktop $

And it never quits... how do I fix that?

@melpomene I'm using linux. I used che chmod command to run the script on the terminal by doing ./script — MFJOE

There's nothing to fix, then. exit exits your script, as designed. — melpomene

@anubhava yes it is on a text file. I forgot to mention that there is "#!/bin/bash" at the beginning of the script — MFJOE

@melpomene look at the updated description so you can see the output I get... — MFJOE

the terminal wont close with the command "exit"

That's because you run the exit command inside a script. There exit means "exit the script", not "exit the terminal". If you want to close the terminal window from a script, you probably have to use commands like kill $pidOfTheTerminalWindow.

As an alternative, you can source the script, that is execute the script as if you typed it directely into the command line. Use either

source sxdd

or

. sxdd

Alternatively, run the script commands directly in the current shell with . ./sxdd.

Try to run your script like this: exec ./sxdd

It replaces the shell process with your script and when the script exits your window will close.

A similar question was asked on Ask Ubuntu. It was suggested that you could put kill $PPID at the end of the script which will send a SIGTERM to the parent process. You could also do this:

echo "You can close this window now"
sleep 100
kill $PPID

Which would prompt the user to close the window and then forcibly close the window using the other method.
