cronpi 2.0.0

a small crontab deploying package for python

   

cronpi

A small tool for deploying crontab jobs into a unix-like system, eg. Linux/Mac from python.

cronpi makes jobs more human readable and works on both 2.X and 3.X version.

Installation

pip install cronpi

Usage

cronpi has following functions

SN	Name	Description
1.	run_by_date	job that runs just once by setting date in format YYYY-MM-DD HH:mm
2.	run_every_day	job that runs every day at given time HH:mm
3.	run_every_week	job that runs every week at the given time of given weekdays
4.	run_every_month	job that runs every month at the given time of given days of a month
5.	run_every_year	job that runs at the given time of given days of given months
6.	run_custom	command will be exactly similar to single line which we write during "crontab -e"

Each functions take two parameters

<command to execute>, <isOverwrite=bool>?

parameter	type	description
command	string	This command will be executed as scheduled
isOverwrite	bool	It is optional and default value is false, which means cronpi will always insert new job

cronpi will always install a new cron job if only command is passed as parameter or isOverwrite is set to False. If command passed as first parameter already exists in cronjon and "isOverwrite=True" is passed as second parameter ,then it will update the time of running the job instead of adding new job.

cronpi.XXXX("/some/command", isOverwrite=True)

Use Case 1 - Run once

1. Run a job at 20th october 2020 at 5:30PM

cronpi.run_by_date("/some/command").on("2020-10-20 5:30pm")

Use Case 2 - Run every day

1. Run a job daily at 5:30PM

cronpi.run_every_day("/some/command").on("5:30pm")

Use Case 3 - Run every week

1. Run a job at every sunday at 5:30PM

cronpi.run_every_week("/some/command").on("sunday", time="17:30")

2. Run a job at every saturday and sunday at 5:30PM

cronpi.run_every_week("/some/command").on(["sat", "sun"], time="5:30PM")

Use Case 4 - Run every month

1. Run a job at every 10th of a month at 5:30PM

cronpi.run_every_month("/some/command").on(10, time="17:30")

2. Run a job at every 10th and 20th of a month at 5:30PM

cronpi.run_every_month("/some/command").on([10,20], time="17:30")

Use Case 5 - Run every year

1. Run a job at every 10th january at 5:30am

cronpi.run_every_year("/some/command").on("january", day=10, time="5:30am")

cronpi.run_every_year("/some/command").on(["jan", "oct"], day=10, time="5:30")

Use Case 6 - run like crontab

Add a job to crontab by passing the command that we input to "crontab -e" command.

cronpi.run_custom("* * * * * /some/command")

# ┌───────────── minute (0 - 59)
# │ ┌───────────── hour (0 - 23)
