what is the script which runs at the exit bash shell

supersubu123 · 01-23-2007, 11:23 AM

hi

this is my first qn in this forum.
.bashrc runs at the startup of bash shell(am i correct?)
is there any similar script which would run at the time exiting the bash shell alone.
my aim is to set some environmental variables when entering the bash shell.
and again resetting them to their original values when i exit it.

As far as I know, environment variables will not be altered outside of a particular instance of bash (or some other shell) anyway:

Code:

zmk@darkstar:~$ export TEST=a
zmk@darkstar:~$ echo $TEST
a
zmk@darkstar:~$ bash
zmk@darkstar:~$ export TEST=b
zmk@darkstar:~$ echo $TEST
b
zmk@darkstar:~$ exit
exit
zmk@darkstar:~$ echo $TEST
a
zmk@darkstar:~$

I have no .bash_logout script.

Actually .bashrc is not run at startup unless invoked by /etc/profile then ~/.bash_profile

To understand more about the order, check out this from a quick google search: http://linuxreviews.org/beginner/Bas.../en/c1309.html

Yes and for anyone that didn't know, all of the bash environment files in a users home directory don't exist, it will revert back and use /etc/profile

the location of all the scripts gets moved around all the time in all the different distros, sometimes i have to go to like 3 files before i can set my shell shortcuts. grrr
