~/.bash aliases

With an alias you can simplify the execution of big and complex commands assigning an alias to the big command and using the alias as a new command.

Bash alias is often defined in ~/.bashrc file. However, it is possible to use ~/.bash_aliases file too on certain Linux distros.

You may want to put all your additions into a separate file like ~/.bash_aliases, instead of adding them directly to ~/.bashrc file.

Calling ~/bash aliases

The ~/.bash_aliases must be called by your $HOME/.bashrc file as follows:

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

The ~/.bashrc file is executed every when you start a new terminal session. If you don't want to start a new terminal, run the follow command to execute your changes:

source ~/.bashrc

Sample ~/.bash_aliases file

alias occ='docker compose exec -u www-data nextcloud occ'
alias nextcloud-mysql='docker compose up nextcloud mysql nginx mailhog redis'
alias nextcloud-pgsql='docker compose up nextcloud pgsql nginx mailhog redis'
