No Jenkins programs use whatever niche shell you run on your machine, e.g. fish or kitty.
We only ask you to not be a monster and wrap your lines at 80 characters.
If it worked when you tried it, there's not much else to do.
That said, always validate your crontab, no one gets them right, even on the tenth try.
The No Jenkins community likes crontab.guru Note: They are not a paid sponsor, but we did receive the product free.
Append &> /dev/null to all commands and you're good. This will save you
loads of cash on disk space and monitoring.
