Description Philippe Vouters 2012-05-28 11:34:09 UTC

Description of problem:
As per Michael Schmidt request in https://bugzilla.redhat.com/show_bug.cgi?id=790768 I am entering a new bash-completion problem report. It happens that with bash if your type in $ ls $HOME/<TAB> you get $ ls \$HOME/

Version-Release number of selected component (if applicable):
bash-4.2.24-1.fc16.i686
bash-completion-1.3-6.fc16.noarch

How reproducible:
Always

Steps to Reproduce:
1. Activate a terminal running a bash shell
2. ls $HOME/<TAB>
3.
  
Actual results:
ls \$HOME/

Expected results:
ls /home/philippe/

Additional info:
For an example of environment variables auto-completion, read the following GNU readline example at:
http://vouters.dyndns.org/tima/Unix-Linux-OpenVMS-GNU_readline-readline_with_filename_completion_example.html

I do not know if this is a bug or a bash intended feature.
Yours truly,
Philippe Vouters (Fontainebleau/France)

Bash development team says that this was an intentional change with Bash 4.2.

Very annoying this is an intentional change.

Hopefully they will merge direxpand branch with master branch.

Comment 3 Roman Rakus 2012-05-29 12:45:39 UTC

Anyway, this is related to bash and not bash-completion, isn't it?
