Terminal error message

Back up all data.

Select

Shell ▹ New Command

from the Terminal menu bar. Uncheck the box marked

Run command inside a shell

if checked.

Copy and paste the following line into the text box that opens, then press return:

mkdir disabled_shell_files

Close the Terminal window that opens. Repeat with this line:

mv .profile .bash_history .bash_profile .bashrc .inputrc disabled_shell_files

Your old shell initialization and history files will be saved in a directory named "disabled_shell_files" at the top level of your home directory. It's normal that some of these files will not exist, and therefore you will get some "no such file" errors.

Close the window, open a new one, and test.
