Hi
When executing some commands, we need to re-login into the account.
What happens when logged out and login ?

Are there any scripts (.bashrc .... ) to be executed or to update system files.
Help Me ..........

if you source a shell script that has the exit keyword in it, your process ends and you have to login again. No regular user command, like ls, awk, etc. will do that.

# sourcing a script note the leading dot
. myscript
# sourcing a script on linux - you can do this as well as the dot notation
source myscript
# this will not log you out
myscript

kill $$
