Question

I'm just moved from linux to mac, and one of the problems I'm having is that tab completion is only 1 level deep, and I'm not sure how to correct that.

Let me explain by example - when I used git on ubuntu, I'll start typing

$ git

and hit tab, and the shell would complete the command or display the options available for the letter\s I've typed. That's what happens on my mac as well (1 level). However, when I'd continue typing the next part of the command

$ git commit

and hit tab, mac terminal would not complete the next subcommand (for git) as it would in Linux. Same goes for other programs that support this multilevel command completion. I suspect this might be a readline library issue, but I'm not sure which one I should install.

Answer 1

Download bash_completion and source it from your .bashrc. Then put contrib/completion/git-completion.bash from the git distribution into bash_completion.d.

Alternatively you can install it via MacPorts.

Answer 2

For git there is an option available on compilation to support completion.

If you used port to install Git (which I recommend), you can reinstall git with this command

sudo port install git-core +svn+bash_completion+doc

Which will install git with bash completion, git-svn support and docs

Answer 3

This is definitely a bash configuration issue (since I get this behavior on mac + alot more that I have configured it for, like hostname completion) You should look around for power scripts for bash and add them to your profile.
