exit script

[zoonkai]

I'm trying to create a simple exit script. The applications being run by the end user are predominately CAPS Based. I would like to create a script call EXIT that exits out of unix

I have created executable scripts that contain (without quotations)

"exit"

and also

"exec exit"

neither one worked...

when i do "exit" or "exec exit" at the command prompt...it works fine.

Any help would be greatly appreciated.

Thanks Donald (Zoonkai) Dixon

zoonkai,

'exec exit' and 'exit' will both work fine from the command line but will not work from within a script because when you call exit (or exec exit) from the script it exits the script, not the command line.

Try using the 'logout' command within your script.

Hope this helps. Regards,
Chuck

I'm getting the same failure this was as the other ways.

donnan # l EXIT
-rwxrwxrwx 1 root sys 7 Feb 5 10:49 EXIT
donnan # pwd
/zoonkai
donnan # /zoonkai/EXIT
/zoonkai/EXIT: logout: not found
donnan #

can you just set up an alias in their .profile
alias EXIT=exit
so that EXIT and exit are the same command

 

[zoonkai]

same thing

Sorry, try this in the .profile
alias EXIT='exit'
you need to put single quotes around the system command

 

[freavis]

you can also create a script called EXIT and put one line in it
'exit'
single quotes around it
and make it executable
and that will work also

 

[zoonkai]

Still no luck....putting in profile gets
$ EXIT
EXIT: not found
$
****************************************************
creating command and running...just nothing happens

donnan # pg EXIT
'exit'
donnan # l EXIT
-rwxr-xr-x 1 root sys 7 Feb 5 13:14 EXIT
donnan # pwd
/bin
donnan # EXIT
donnan #
****************************************************

I'm assuming you were referring to the asterics on the same key as the quotation marks....but just in case, I tried the ones to the left of the "1" key....and no dice with that attempt either

As far as I understand it alias is not available in bourne shell
man alias = ......

Limitations
===========

The versions of alias and unalias described here are available as built-in
commands in ksh(C).

There is no aliasing mechanism available in sh(C).

The alias and unalias commands built into csh(C) differ from those described
here.
__________________________________-

if you want them to be logged out after exiting the menu1 program you could just add the exit command as the last line of their .profile. this is not secure, since they can break out before the exit command is executed, but if you need security you can trap these signals. (ie trap 'continue' 0 1 2 3 15)

None of what you've tried is going to work

What you need is a script that kills off the shell of its parent process.

Some shells make that easy- bash, for example sets PPID to the parent But you can do it yourself in .profile:

PPID=$$
export $PPID

Then your EXIT script (which must be somewhere in their PATH or they have to type ./EXIT) is just:


# EXIT script
kill -9 $PPID

In the .profile I put this


PPID=$$
export PPID <-----(no &quot;$&quot

and the script is like this..

donnan # pg EXIT
kill -9 $PPID
donnan #

This worked =)

is loging out by using the kill command going to cause any &quot;undetermined results&quot; over time or is it basically the same as logging out with the exit command?

Thanks!!

It's a little different but shouldn't cause any problems.
