First I would like every one for helping me, It's working well now after I changed the alias to .profile as BobHarris saidto me
Some information to keep in the back of your mind.
By default macOS sets the default shell to bash. The fact that you are using sh means there has been some change made to your macOS setup. Whether you did this intentionally, or by accident, you should keep this in mind.
And the reason you should keep this in mind is that if you create a new account, or switch to a different Mac, you may find that in the new environment bash is now your shell, and assumptions you were making in your current environment are not working the same in the new environment.
And now that you have BOTH a .bash_profile _AND_ a .profile, you should know that if you magically switch back to bash, that when bash starts up it looks for one of the following 3 initialization files in the following order, and will use the first it finds, then ignore all the others
I mention this, because if you end up back with bash in your current account, it will start using the .bash_profile you currently have, and ignore the .profile you may have built up. This will be confusing, so keep this bit of information in the back of your mind. Unless of course you delete the .bash_profile, then bash will also find your .profile.
Confusing, isn't it 😕
