Running python scripts consecutively in Crontab

Question

I am attempting to run my compilation of scripts one after another every minute. Example: Assuming each script takes 2 seconds to finish:

start script 1 at 1:00, script 2 at 1:02, script 3 at 1:04, etc...

I assume it should look something like this

*/1 * * * * python script1.py && python script2.py && python script3.py

Answer 1

* * * * * python /path/to/script1.py ; python /path/to/script2.py ; python /path/to/script3.py

Use && if you want to run the second script only if the first script is successful (exit code is 0)

Use ; if you want to always run the second script irrespective of first script's exit code

Always provide full path to your script in crontab

Answer 2

Your cron entry is fine.

You may want to create a wrapper script that calls all your scripts in sequence.

Answer 3

Your cron entry should work. However, you may notice that it may fail because you didn't specify the absolute paths for the scripts.
