: I noticed that even if you do a cd inside a Korn-shell script,
: upon exit from the shell you will still return to the dir whence
: you came.

Because child processes cannot change their parent. When you
execute a script, you are spawning a new (child) process.

: Is there any way you can go to some other dir when U exit from
: the shell ???

You can 'source' my_korn_script thusly:

. my_korn_script

You can, however, simulate this behavior by starting the script with the exec
command, which causes the process started by the script to overlay that of
the parent (interactive) shell, rather than forking as usual.

For example:
2 barnyard> cat trial  # not a Useless Use Of Cat(tm) :-)
#!/bin/csh
cd /
csh -i

3 barnyard> pwd
/LocalUsers/tmc
4 barnyard> exec trial
1 barnyard> pwd        # now in the interactive shell started from script.
/
