Launchify
Launchify is a tool that makes it super easy to schedule programs to run on
a regular schedule on macOS. As an example, to schedule a program myprog to
run ever 5 minutes:
$ launchify 5m myprog
Under the hood, launchify registers your program to run using launchd. It
writes a boilerplate config file to ~/Library/LaunchAgents and sets it up to
write logs to ~/logs/myprog.
Install
Install requires the rust toolchain, which may be installed like:
$ curl https://sh.rustup.rs -sSf | sh
Then install using cargo:
$ cargo install launchify
Advanced Usage
To see full CLI options, run launchify -h.
You can specify the period to run the program over as (d)ays, (h)ours, (m)inutes
or (s)econds. For example, to run myprog once an hour:
$ launchify 1h myprog
Extra program args may be specified via the --args option
$ launchify 5m myprog --args="--foo bar"
You may override the default name used to label the launchify job and log
directory via --name. By default the name is derived from the program filename.
$ launchify 5m myprog --name=my_awesome_program
Comparison to launchctl
launchify is not intended to replace launchctl but is a convenience tool
to complement it. launchify purposely does not support the full configuration
options which may be passed to launchctl but optimizes for a common use-case.
After scheduling a program using launchify, you will find the configuration
file written to ~/Library/LaunchAgents/com.<name>.plist. To stop running
the program, run:
$ launchctl unload ~/Library/LaunchAgents/com.<name>.plist
