tabtab

Create and install double-tab ('tab tab') auto-completions for any command-line application on any shell (bash, fish, ksh, etc). When you use the command-line, you can double-tab to auto-complete the name of a command-line application or a target file or folder. Its possible to provide your own completions for applications: git comes with bash shell completions, and the fish shell includes a library of completions for many applications.
