Bash allows auto-completion using the tab key:

If you type cd ~/D on Terminal, followed by the Tab key, you ear a beep, but if you follow by a second Tab key, the Terminal display the suggestions Desktop/ Documents/ Downloads/. If you type "e" followed by Tab, the auto completion displays cd ~/Desktop/, that is (here) the only folder in Home folder who begins with "De".

For whatever reason it stops to work for me after a while using Terminal or Iterm2. How can I diagnose and fix this?

  • What is the value of the various bash variables controlling tab completion (check the man page) after it stops working? – nohillside Mar 21 '19 at 6:55
