Bash-completion troubleshoot @ayshik-halder

This is a step by step guide to troubleshoot and reconfigure auto tab completion on linux systems.

You can replace the /etc/bash.bashrc file with the bash.bashrc file on my repo.

First start by checking the basics;

• Running echo $SHELL confirmed I was indeed using a bash shell.

• Running dpkg -s bash-completion confirmed bash-completion package was installed.

• Next I took a look at the /etc/bash.bashrc file and I found the section to “enable bash completion in interactive shells” had been commented out for some reason. It is not something I would have knowingly done, so the reason why the section was commented out is a bit of a mystery.

• • I changed the section from;

  # 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 # fi #fi

  To

  # 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 fi fi

• I saved the /etc/bash.bashrc file

• Closed my current bash shells

• Opened a new one and tab completion was working fine again.
