I hope Pierre will not implement this...

Seriously? No. 1) I cannot rename anything to google-* due to legal reasons and 2) the solution is not to rename binaries but using a more sane completion (e.g. the zsh menu based completion)

Let me add another note: If a completion system does not work it cannot be a solution to alter what you want to complete. Instead have a look at this:

# pacman -S zsh grml-zsh-config
# zsh
# chr<tab><tab><tab> (if there are more alternatives use cursor keys)
# once you had used chroot type chr< up key> to choose the command from history.

Surely creating a symlink from chromium to google-chromium could solve this?

Obviously for the mentioned legal reasons dont have this in arch itself but should someone need this have a wiki entry on how to perform the task?

Would that not be a acceptable solution?

Nell, it was more that chroot was being 'blocked' by chromium.

Oh, sorry for misunderstanding the issue.

Is it possible for different paths (in the bashrc or bash_profile files) to take precedence (such that applications in /usr/bin/ are found before those in /opt) if so do chroot and chromium reside in the same path? My thinking is that if chroot is in /sbin or somewhere else, could it not come first in tab completion?

Alternatively alias chroot in this instance to something shorter? If tab completion is being used then itś being used interactively so an alias might do, or is that not such a good idea?

@disp
I assume you heard about aliases?

Aliases would work ... but it feels a bit wrong aliasing chroot to something else, considering chroot has been a part of unix since before I was even alive.
To be honest, I was not expecting this request to be honoured, but I thought I would try as other linux distributions have gone with google-chrome or something similar.

There are two main reasons why other distributions don't use the name "chromium":

1) They package the Google branded "Google Chrome" (with a binary called "google-chrome") instead of Chromium (as included in Archlinux). While these two pieces of software are quite similar they are not the same. Google Chrome is built upon the open-source Chromium, but Google Chrome itself is not open-source. Therefore, I'm against renaming the "chromium" binary to "google-chrome".

2) Some distributions already include a binary called "chromium", as there is a computer game called Chromium. So they cannot use this name for the browser. However, Debian based distributions recently renamed the "chromium" game to "chromium-bsu", suggesting that they will sooner or later use the name "chromium" for the browser.

I'm against renaming the "chromium" binary. If someone needs "easier" tab completion the best solution is to "fix" the configuration of the shell. Furthermore, I'm sure there are dozens of other packages where tab completion clashes with names of "traditional" *nix software. Do we want to rename all of these binaries too?

Well, let's sum this up: Renaming binaries to alter the order of bash completion is plain nonsense. Sorry, but you are looking at the wrong place to fix your problem.
