Run mpd daemon automatically
Table of contents
In article Install mpd + ncmpcpp on OSX Yosemite, many asked how to run mpd automatically. This isn’t an issue at first, because I run mpd manually. I first suggested to include mpd into your shell rc file, but did not realise that it will run mpd each time a terminal is being opened, e.g., in new tab or window, thus resulting in Address already in use prompt, which may, if not, all the time, annoying. Here, I have come up with this simple snippet to run mpd daemon only if it is not yet running.
While there are ways to run mpd automatically, here’s the easiest way, that I did and now henceforth personally use.
Check your shell
Check what shell you are using.
echo $SHELL
If bash
Open your ~/.bashrc file found in your home directory, or create one if it does not exist yet.
cd
vim .bashrc
If zsh
Open your ~/.zshrc file found in your home directory, or create one if it does not exist yet.
cd
vim .zshrc
Script to conditionally run mpd if not running
Put the following code at the end of the file.
# Start mpd automatically if not yet running.
if [[ -z "$(pgrep mpd)" ]]; then
mpd
fi
Save settings
Save and source your .bashrc file.
source ~/.bashrc
or
source ~/.zshrc
Or, you may just restart your terminal.
This also fixes running mpd twice and multiple times, with the following error as asked by MiGu3l in disqus:
