[Bug 177243] Re: Bash command completion puts backslash in front of beginning dollar sign

[Keith Thompson]

I'm seeing this on Ubuntu 12.04. (I installed beta2 a couple of weeks
ago and have applied all updates since then).

I have commented out the entire body of
/etc/profile.d/bash_completion.sh (due to a different issue).

With a newly created account, no changes to any $HOME/.* files :

$ uname -a
Linux kvetch 3.2.0-23-generic-pae #36-Ubuntu SMP Tue Apr 10 22:19:09 UTC 2012 i686 i686 i386 GNU/Linux
$ echo $BASH_VERSION
4.2.24(1)-release
$ dpkg -l bash bash-completion
[SNIP]
ii  bash           4.2-2ubuntu2   GNU Bourne Again SHell
ii  bash-completio 1:1.3-1ubuntu8 programmable completion for the bash shell
$ echo $HOME/<tab>

produces

$ echo \$HOME/

Title:
  Bash command completion puts backslash in front of beginning dollar
  sign

Status in “bash-completion” package in Ubuntu:
  Fix Released
Status in “bash-completion” package in Debian:
  Fix Released

Bug description:
  Command completion inserts a backslash in front of the beginning
  collar sign of my environment variable.  Example:

  export MYENVVARB=xxx

  cd $MYE<tab>

  results in

  cd \$MYENVVARB

  which is not only seriously inconvenient, but I've never seen any
  standard Bash configuration that does it.  I recommend it be
  configured or programmed otherwise.  Perhaps there is a special mode
  for this, but it should not be turned on in the terminal.  Those
  terminals are places where environment variables will be used a lot,
  and people will want command completion for them.  This is completely
  non-standard.  I'm seeing it in both the standard terminals, and in
  the xterms I use.
