tinycron

A very small replacement for cron. Particularly useful within containers and for distributing cron tasks alongside a project as a standalone file.

sudo mv tinycron /usr/local/bin/
sudo chmod +x /usr/local/bin/tinycron

Usage

tinycron [expression] [command]

Tinycron can be conveniently used in your scripts interpreter line:

#!/usr/local/bin/tinycron */5 * * * * * * /bin/sh
echo "Current time: $(date)"

Or invoked directly via commandline:

$ tinycron '*/5 * * * * * *' /bin/echo hello

Tinycron uses and supports expressions from the cronexpr library. Some examples:

• @daily - run once daily, at midnight
• * 15 * * * * * - run at minute :15 of every hour
• */30 * * * * * * - run every 30 seconds
