You would like the Perl script chdir() to affect the parent shell process? That is impossible in this case as exec() won't return, so when the Perl script ends, the original shell process also ends.

I'm sorry that I have probably misunderstood your question. I would say the method is only for the original process image (shell script in your case) affecting the later, replaced process image (the Perl script in your case), and doesn't work if you expect the parent environment to be influenced after exec(), as it won't return at all.

So, as I understand, whatever the perl script does will not affect the parent shell.

Say, in this case, after I change to the new directory, I cant remain in that new directory even after the perl script exits. Right ?

Absolutely correct. What you are asking: 'Can I source a file from inside perl?'
No. Because you have to call exec. This is exactly the same problem you have with shell scripts doing a cd and then exiting.

Thanks Jim.
