want user will logout from shell on exit of bash script

Hi, I want when linux user exit from shell script it will also log out from bash shell. is it possible?

From serverfault sahil007

• It is possible to do this if you include an EXIT at the end of your script, which tells the bash shell to terminate.

  Julien Vehent : the exit will exit the current bash script, and not the bash of the user running it

  sahil007 : no exit will terminate only that script not the bash shell

  SvenW : This will just exit the sub-shell where the script is executed and doesn't solve the question.

• with kill ?

  $ kill -HUP `ps -ef |grep $USER|grep bash|awk {'print $2'}`
  

  Edit: as said in the comments, it works better with PPID

  $ kill -HUP $PPID
  

  SvenW : There is a variable for that: $PPID

  Dennis Williamson : Yes, definitely use `$PPID`. Using `ps` in that way will log the user out of other sessions, too, which may be very undesirable.
  From Julien Vehent

• End your script with kill -HUP $PPID

  $PPID is the process ID of the parent process.

  Cristian Ciupitu : `$PPID` might fail if the script is run from a subshell, e.g. bash login shell → another bash shell → this script. Also why `-9` and not `-HUP`?

  Julien Vehent : kill -9 closes all processes it can without letting them close their file descriptors, freeing their memory, etc... I don't think it's a good idea if the script does any I/O.

  SvenW : Yes, you are right. Feeling a little bit destructive today ;)
  From SvenW

• Depending on what you are trying to accomplish, you could use the script name instead of the shell in /etc/passwd.

  The last entry in /etc/passwd (everything after the last colon) is the shell that is run when the user logs on. By changing this to the name of your script, when the script ends, then by definition, so does the shell.

  ** Be very careful editing /etc/passwd however, as you could lock yourself out of your machine. Apparently you can do this with

  usermod --shell <script name> <user name>
  

  which would be the safer way to make this change.

• Instead of starting the script normally, exec it instead. This will replace the login shell, so when the script finishes the user will be logged out.
