Easily schedule commands to run multiple times at set intervals (like a cronjob, but for a single command)
hakcron allows you to run a command at specific intervals. It was written with the intention of being able to quickly set up a cronjob in a tmux session or similar, without having to actually edit the crontab.
-c is the command that you wish to run at set intervals.
-f defines the frequency of the command being run.
To run a command daily, you could do:
hakcron -f "daily" -c "curl hakluke.com/dostuff.php"
Similarly, to run hourly, you could do:
hakcron -f "hourly" -c "curl hakluke.com/dostuff.php"
-f can be set to yearly, montly, weekly, daily and hourly:
| Entry | Description | Equivalent To |
|---|---|---|
| yearly (or annually) | Run once a year, midnight, Jan. 1st | 0 0 0 1 1 * |
| monthly | Run once a month, midnight, first of month | 0 0 0 1 * * |
| weekly | Run once a week, midnight between Sat/Sun | 0 0 0 * * 0 |
| daily (or @midnight) | Run once a day, midnight | 0 0 0 * * * |
| hourly | Run once an hour, beginning of hour | 0 0 * * * * |
To be more specific, you can also use intervals like this:
- every 1h30m
- every 5s
For example:
hakcron -f "every 30s" -c "curl hakluke.com/dostuff.php"

Huge thanks to robfig for writing the golang cron library.
