Bash: Schedule jobs on Mac using launchd

schedule_job.sh

# Activate rvm
$ rvm use default

# Install lunchy if not already installed
$ gem install lunchy

# Make a plist file
$ touch ~/Library/LaunchAgents/org.yourusername.email-mom.plist

# Open your plist file and copy the text from below

# Load and start your new agent

## With the built in `launchctl`
$ launchctl load ~/Library/org.yourusername.email-mom.plist
$ launchctl start org.yourusername.email-mom

## Or with Lunchy
## `restart` will unload your agent (if it's loaded), load it, then start the job
## Lunchy sees the argument as a pattern, so you don't have to specify the entire agent-name
$ lunchy restart email-mom

# Show loaded agents
$ launchctl list
# OR
$ lunchy list

# Stop an agent
$ launchctl org.yourusername.email-mom
# OR
$ lunchy stop email-mom
