I've installed Mercurial (1.4.3-1) on ubuntu and it doesn't do tab completion in bash by default. What is the simplest way to enable this feature?

    You should really consider using a newer Mercurial release. There are PPA repositories available for Ubuntu that you can enable to get your normal auto-update behavior of Mercurial in a seamless fashion that won't have you more than a year behind current: https://launchpad.net/~mercurial-ppa/+archive/releases – Ry4an Brase Oct 25 '11 at 02:54

You need to

  • Install an up-to-date package for Mercurial, see the Mercurial PPA. This will give you a /etc/bash_completion.d/mercurial file with the completion code for Mercurial. You can source this file directly to enable completion support for Mercurial.

You can also enable completion support for all programs:

  • Install the bash-completion package: aptitude install bash-completion.

  • Source /etc/bash_completion in your ~/.bashrc file:

    # Use bash-completion, if available
if [ -f /etc/bash_completion ]; then
  . /etc/bash_completion
fi

    This will enable completion for all commands, including Mercurial.

curl https://www.mercurial-scm.org/repo/hg/raw-file/tip/contrib/bash_completion -o ~/.hg-completion.bash && source ~/.hg-completion.bash

The mercurial autocomplete script appears to be maintained here:

https://www.mercurial-scm.org/repo/hg/file/tip/contrib/bash_completion

source this script in your .bashrc or equivalent

System wide

for all users.

$ sudo curl https://www.mercurial-scm.org/repo/hg/raw-file/tip/contrib/bash_completion -o /etc/bash_completion.d/mercurial
$ source /etc/bash_completion.d/mercurial

The bash_completion script location has changed so you need to do

curl https://www.mercurial-scm.org/repo/hg/raw-file/tip/contrib/bash_completion -o ~/.hg-completion.bash && source ~/.hg-completion.bash

instead of 

curl http://www.selenic.com/hg/raw-file/tip/contrib/bash_completion -o ~/.hg-completion.bash && source ~/.hg-completion.bash

  • This answer is cross-platform and doesn't need Ubuntu. I used it on OS X. It should work everywhere you have `bash`, `curl` (and `hg` ;-). – Ludovic Kuty Jan 16 '17 at 16:49
  • Worked for me on OSX. Thank you! – Brodan Apr 10 '17 at 15:00
  • You should update this to include adding `source ~/.hg-completion.bash` in your `.bashrc` so that you don't have to run this in every new shell. – Brodan Apr 12 '17 at 21:43

Since it's neither tagged nor titled "ubuntu", and because googling with fedora also leads here, I'll add a variation on Martin's answer that works by referencing /etc/bash_completion.d/mercurial.shinstead of /etc/bash_completion in your ~/.bashrc:

# Use bash-completion, if available if [ -f /etc/bash_completion.d/mercurial.sh ]; then . /etc/bash_completion.d/mercurial.sh fi

Not sure if the OS makes this distinction necessary, but this works for me on Fedora 11 through 20.

Correction: Fedora 11 and Fedora 20. (Not tested 12-19.)

Install bash-completion package in your Linux (depends on Linux Distribution you are using).

Then go to /etc/bash_completion.d/ and create a file called hg and put the content of this script (below) into created hg file.

    Unfortunately the link above doesn't seem to work anymore - results in a 403. – robjohncox Mar 23 '15 at 12:55
  • I think this is the new location for `bash-completion` (at least according to the Debian Bullseye repo): https://github.com/scop/bash-completion .. heres some more info on it: https://stackoverflow.com/a/74662464/4240654 – alchemy Dec 02 '22 at 23:19
