How to Enable Tab Completion in Mac OS X Terminal

• Use pico, nano, vi or whatever your favorite text editor is to edit/create .inputrc, I’ll use pico for this walkthrough.

pico .inputrc

• Paste in the following three lines of rules:

set completion-ignore-case on
set show-all-if-ambiguous on
TAB: menu-complete

• Press Control+O to save changes to .inputrc followed by Control+X to quit
• Close and reopen Terminal for the rules to take effect
• Start typing a path or command and press the Tab key to see this feature in action
