how to logout through a shell script 1

[mckarl]

ok, i need a way to <b>logout</b> from within a <b>shell script</b>.<br>
basically, here's my plan.<br>
<br>
any previouse day -<br>
<br>
box administrator1: Please all remember to log out when you go home.<br>
<br>
me: home time ~~BBBRRRRRRRRRRMMMMMMMMM~~<br>
<br>
<br>
This morning:<br>
<br>
box administrator1: you forgot to log out <i>yadi ya ya ya </i><br>
me: *wakes up just as he finished, with a hangover* sorry.<br>
<br>
+++++++++<br>
<br>
Now, this repeats itself for 4 1/2 months now??<br>
<br>
So, i decide today, i am going to build a logout-<i>thingy</i>.<br>
<br>
1. Make use of the <u>at</u> command to run script at 5:00pm<br>
2. Make a program that is executed asking me if i want to continue, and if i dont reply after 30 seconds or so, it logs me <b>out</b>.<br>
3. Make a brew.<br>
<br>
++++++++<br>
<br>
Can anyone please tell me how to <b>logout</b> from within the script i want to create in step 2.<br>
<br>
++++++++<br>
<br>
Thanks!!!!<br>

You could tuck away the PID of your login shell in a file - then your 'at' job could kill it at a specified time. But that doesn't ask you if it's ok to do so. You could get it to send you mail - at one minute intervals until the logout time to give you a chance to cancel the kill job.<br>

Can't you use the TMOUT variable of the Korn shell? if you give a value greater than 60 (seconds) it will log you out automagically...<br>
<br>
I hope it works

Well, i looked at it, and it's fairly easy to operate (Simple in fact)<br>
<br>
eg:<br>
<br>
############################<br>
<br>
&lt;.profile&gt;<br>
------------------------------------------------------------------------------------------------------------------------<br>
#set logout time as 2 mins:<br>
export TMOUT=160<br>
<br>
------------------------------------------------------------------------------------------------------------------------<br>
<br>
-- after 16 seconds (2 mins)<br>
<br>
Prompt:<br>
<br>
timout in 60 seconds:<br>
-- if no input--<br>
timeout waiting for input from user<br>
<br>
<br>
Simple!!!<br>
<br>
<br>
<br>
<br>
All you got to do, is set : TMOUT=160 in the profile (.profile) and BINGO!<br>
<br>
<br>

You must to remember it is a Korn Shell variable, if you don't leave your terminal/session in the ksh, then you won't be logged out. The C Shell (or it is bash?) have TIMEOUT, with the same func.<br>
<br>
You can make the variable readonly with <br>
readonly TMOUT<br>
<br>
I hope it works<br>
