[Enhancement]: enable bash completion

[boukendesho]

What changes would you like?

Is it possible to enable bash completion ?

Any extra information?

~I've tried terraform -install-autocomplete but don't work.~

And i found this bash completion script from gist

[boukendesho]

Sorry , terraform -install-autocomplete works. I forget restart my shell.

But is it possbile that enable bash completion by default with snap?

+1 on this.

Doing quick examination, terraform -install-autocomplete simply adds the following line to your bashrc:

complete -C /snap/terraform/711/terraform terraform

(Or I guess equivalent for the particular revision.)

A completion file that simply contains complete -C /snap/bin/terraform terraform and a completer key in the app entry should be sufficient.

Hmm, gave that a go locally, but no dice.

Will try a bit later if I get time, but feel free to have a play!
