like 2 days in a week at a certain times when I open my notebook.
If you want to always execute something use /etc/crontab
. It has 5 elements for specifying a moment, a user, and a command to execute.
crontab.guru/ is a website where you can check crontab rules.
You can use vim
or nano
to edit (vim /etc/crontab
and add
0 1 * * 2,5 rinzwind /usr/bin/clamscan -r --move /home/myusername/Quarantine /home
(assuming it is in /usr/bin
) and it would run this with user rinzwind at 1AM on weekdays 2 and 5 (sun=0, so these 2 are tue and fri) -if the machine is on-.
