Bash: Autocomplete doesn’t work properly


bash completion extends bash’s standard completion behavior to achieve complex command lines with just a few keystrokes. This project was conceived to produce programmable completion routines for the most common Linux/UNIX commands, reducing the amount of typing sysadmins and programmers need to do on a daily basis.



Step 1: Install bash-completion

$ sudo apt-get install bash-completion

And some times it works if we re-installed it by the follwing command:

$ sudo apt-get install --reinstall bash-completion

Step 2: Enable bash-completion in your .bashrc file

Open your gedit ~/.bashrc and if these content doesn’t exist there, add them at the end of it and save it.

# enable bash completion in interactive shells
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion

Important: Logout and log back in and reopen your Terminal. It should be fix now.
