Ubuntu – How to get bash to stop escaping $ during tab completion

bashcommand line

I have this on the command line:

ln -sf $PWD/wine-

and then I hit Tab to complete the filename. In earlier versions of Ubuntu, this worked just fine to complete the wine- filename (and as a side-effect $PWD would be expanded at that time). But now it turns it in to

ln -sf \$PWD/wine-

which isn't what I meant at all and doesn't complete anything as the file does not literally start with $.

How do I get completion back to the less broken behaviour?

  • I've found that bash versions >= 4.2.29 have a new direxpand shopt setting. (See man docs/bash.1 if you check out a new bash, or see bash.1 from line 8951)

    If one uses Quantal Quetzal 12.10 or otherwise gets hold of (or checks out and builds) a new bash, then:

    shopt -s direxpand

    Gives me the behavior I want, need and love.

    Workaround: In the meantime, Ctrl+Alt+E instead of Tab does what I want too. But is awkward.

    BTW, There are several threads called "bash tab variable expansion question?" in gnu.bash.bug. From reading them, I found the info here.
