hakcron

Easily schedule commands to run multiple times at set intervals (like a cronjob, but for a single command)

Description

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.

Flags

-c is the command that you wish to run at set intervals. -f defines the frequency of the command being run.

Example

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 * * * *

Intervals

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"
