I've worked in Linux before where when I press tab it autocompletes until it becomes ambiguous. If I pressed tab twice at that point it would give me a list of all possible completions.
My current Linux environment does not have the second feature(enabled?). So if I press tab it will autocomplete but it won't list all possible completions after that.
How can I add/enable this feature?
EDIT: turns out it's in csh not bash
/etc/bash_completionfile coming with bash, which you only need to source In you own session startup scripts (or enable site wide in/etc/bash.bashrc).
