如何在linux上的cron作业中安排bash文件

Question

i am trying to schedule a bash script (cron.sh) in cron jobs below is my bash script code

cron.sh : (Please correct it if something wrong)

#!/bin/bash 
#chmod +x cron.sh

sh cron.sh

But i want to schedule the above cron.sh file in crons jobs to run for every two mins

can anyone let me know how to do above

Answer 1

It's worth mentioning that, if your .sh is just a "wrapper" for the .py, you can add the following line to the beginning of you Python file:

#!/usr/bin/python

And then make it executable:

$> chmod a+x code.py

Then you can add directly your Python file as a cronjob following the instruction that m4573r explained. (of course, '~/cron.sh' becomes 'path/to/cron.py').

Answer 2

You can schedule the job by running crontab -e and adding the following line in the end: */2 * * * * /path/to/cron.sh .

You should read man cron for more informations.
