The easiest solution is using sudo powers create a file like this in /etc/cron.d/:
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
@reboot root mkdir /cronjobs
@reboot root sleep 10
@reboot root mkdir /cronjobs/demofolder
This avoids the use of a script file altogether and works for all users regardless of their home directory name, ie /home/steve, /home/mary, etc.
Edit - Add sleep 10
For whatever reason cron is working too fast, or kernel is working too slow when making directories. An extra line sleep 10 was necessary between the two mkdir lines.
You may not need 10 seconds in between the two make directory commands but 10 works on my system with an SSD.
Edit 2 - Make full directory path in one command
As per comments below a simpler method is to use:
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
@reboot root mkdir -p -v /cronjobs/demofolder
-p(long version--parents) tellsmkdirto automatically create all directory parent levels if they don’t exist.-v(long version--verbose) tellsmkdirto print the names of all directories created.
