I opened the terminal and tried to type in the commands but the terminal is showing the message

login: -h option: operation not permitted [Process completed].

How to solve the problem?


  • How are you opening terminal? Have you made any changes? For what it's worth, the Login option -h is only allowed for root/super-user, hence the error on a non-root shell. How that happened for you is beyond me. – cde Nov 30 '15 at 6:22

Can you try running this and rebooting and see if it works after that?
