Hi,
i am trying to "cd" in my shell script but as soon as the script finishes execution the current directory becomes the old directory from which the script was run.

How can i make the change permanent.

before script execution PWD is /export/home/vbhargav

#!/bin/sh

TOCHANGE=/data/bmw/welcome/

cd TOCHANGE

echo "${PWD}" <--- this prints /data/bmw/welcome/


exit 0

After script execution PWD becomes /export/home/vbhargav again

Please help

By default the shell runs your script in a shell which is different from the shell you logged in . So when the script exits , you come back to your own shell ,hence the old working directory .
To make the change permanent you need to run your script in the same shell as you have logged in . To do so precede your invocation script with a "." (dot) , to specify the same shell . This will change to the directory you want .
e.g $ . <myscript.sh> instead of $<myscript.sh>
Let me know if that works
Thanks

I tried ./myscript.sh but the result is still the same.

Thanks for letting me know . Guess I forgot to say that explicitly . There should be a space between the dot and the script name e.g
$. myscript.sh . This will tell the Shell to run the script under the same shell .

Let me know if this works
Thanks

you must use the $ to use the value of a variable in a shell; so:

cd $TOCHANGE
