Subject: Tab completion for mount has extra escape characters when spaces are present

Date: Sun, 17 Oct 2010 19:06:53 -0700

Package: mount
Version: 2.17.2-3.3
Severity: minor

Whenever you type the mount command in the terminal and tab-complete a mount
point with spaces, extra escape characters are present. For example:

mount /media/Shared\\\ Files

Notice how there's 2 additional escape characters, which would cause mount to
fail unless I go back and edit it, which removes the point of tab completion.
Other commands, such as ls and even umount work properly, so that leads me to
believe whatever configuration is set up for the tab completion is wrong for
mount.

After a little more experimentation, it appears that it only adds extra
escape characters if mount (and unmount) are preceded by sudo. The only
reason why umount worked for my test in my original message is because I
didn't specify sudo. Adding sudo in front of other commands, such as cat and
ls still works with tab completion, so it still seems to be limited to mount
and umount.

Not sure what is delivering tab-completion logic for mount, but it's not the
mount package.  What shell are you using?

I'm using the standard bash shell. Many programs seems to have rather
complex tab completion behavior, including command line options and
additional arguments to command line options. For example, after "apt-get
install" it knows the next argument is a package name. I figured that there
was a configuration file for those tools to describe that behavior, rather
than being built into the shell for a particular set of tools, especially
from the variety of tools that have that behavior. I guess it's also
possible that most programs do have such a configuration file, but mount and
umount don't, and the default behavior with sudo is wrong.
