The "exit 10" just tells the script to return an exit status "10". It does not mean it will close the terminal in 10 seconds.

You can source the script so that it runs in the current shell:

Example:

Code:

[root@atlas tmp]# ps -p $$			## Current shell is bash
  PID TTY          TIME CMD
12755 pts/0    00:00:00 bash

[root@atlas tmp]# ksh				## Change to Korn shell (parent process is bash)
# ps -p$$
  PID TTY          TIME CMD
12809 pts/0    00:00:00 ksh

# /tmp/script.sh				## Runs the script in a subshell
Hello, World!
Knowledge is power.
shutting down terminal in 10 seconds

# ps -p$$					## Upon execution, shell is still KSH
  PID TTY          TIME CMD
12809 pts/0    00:00:00 ksh

# . /tmp/script.sh				## Now force the script to run in current shell
Hello, World!
Knowledge is power.
shutting down terminal in 10 seconds

[root@atlas tmp]# ps -p $$			## KSH got closed. Current shell is now bash.
  PID TTY          TIME CMD
12755 pts/0    00:00:00 bash
