Hello,

Who/what is reading this /etc/bash_completion file? Is bash itself
automatically loading this file? I'm asking because on my distro, I
have /etc/bash_completion.d/ and no /etc/bash_completion.

It seems like my bashrc here is automatically
including /usr/share/bash-completion/bash_completion, and otherwise
falls back to /etc/bash_completion:

  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi

Basically, my concerns are:

 - You are using ">" for the redirection. Are we going to be the only
   package writing to this file?

 - Do we support having other packages contribute additional bash
   completion logic?

Thanks!

Thomas

I'm using different Linux distribution and the bash_completion install is not
the same everywhere.

The bash-completion package install bash_completion script in
/usr/share/bash-completion/bash_completion and all completion script to
/usr/share/bash-completion/completion.

So, I guess that files located un /etc/bash_completion.h is distribution specific.

On my Fedora 27 I noticed that /etc/bash_completion is a symlink to
/usr/share/bash-completion/bash_completion.

On my Ubuntu 16.04 I have /etc/bash_completion.d/ and /etc/bash_completion script.

Same here with my Ubuntu 16.04.

I'll check this indeed.
The Buildroot Makefile take care to remove /etc/bash_completion when bash is not
selected. This means that some packages install some stuff here.

I'm wondering if we should let the user decide how to their
bash_completion/bashrc settings.

Best regards,
Romain
