This is a quick tip on how to quickly and easily enable Bash completion for Zato commands - each time you press Tab when typing a Zato command, its arguments and parameters will be auto-completed.
First off, note that when you install Zato from a .deb or .rpm package, it already ships with the Bash completion functionality and what is needed next is its activation as such.
Thus, there is only one prerequisite, core package needed. For example, this command installs core Bash completion in Ubuntu and Debian:
$ sudo apt-get install bash-completion
Enable Bash completion
Again, each operating system will have its own procedure to enable Bash completion.
For Ubuntu and Debian, edit file ~/.bashrc and add the commands below if they do not exist yet.
# 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
Afterwards, Bash completion will be enabled in every future session and you will be able to use it in the zato command, e.g.:
$ zato st[tab] # This will suggest either 'zato start' or 'zato stop' $ zato start /path/to/[tab] # This will suggest a file-system path to use
