Shell script

Hi Friends,

I have a query about shell script.
Simply when we write a simple script like:-

cd /E*Fare/dist/src;pwd

and executing the script from ~/aksutils location we can find in /E*Fare/dist/src location but pwd output still shows the location ~/aksutils.

Thanks-
Shankar

When you use cd in a script the script will change back to the starting dir on exit - i.e. back where you began.

If you wish the script to be able to change the working directory in you current shell, you must source the script instead of running it as a command. For example:

Code:

$ pwd
/home/user
$ echo "cd ~/misc" > testscript
$ . testscript
$ pwd
/home/user/misc

The dot followed by a space is what tells your shell to source the script. Everything in that script will then execute in your current shell ... so be careful what you do!

It's working perfectly.

I have also tried:
$. ./testscript

Thanks All.
