bash auto completion usage

when you have an auto completion file and you want to use it , you have to put the file in the /usr/share/bash-completion/completions/ folder .

then you have to edit the ~/.bashrc file and add these line in the end of your file . for example I have a mdbook bash auto completion file and I want to use it , first I put the file in the /usr/share/bash-completion/completions folder and then I come and edit the .bashrc file .

// snip

# mdbook auto completion file loading
source /usr/share/bash-completion/completions/mdbook

then save file and exit terminal . now enter this command in the shell .

. ~/.profile
