You need to create a script containing the nohup

Script example (/tmp/
nohup /tmp/jobs/startjob &

Crontab example:
15 8 * * * /tmp/ >>/tmp/ 2>&1

Crontab line shoul of course be :
15 8 * * * /tmp/ >>/tmp/cronjob.log 2>&1

15 8 * * * /tmp/ >>/tmp/cronjob.log 2>&1

Why I need this >>/tmp/cronjob.log 2>&1 after my script?
And what does this &1 mean?

How can I quit my script while the nohup job is actually running?

"...Why I need this >>/tmp/cronjob.log 2>&1 after my script?..."
--> This prevents any outputmail to be send to the cronjob owner? This is not required.

"...And what does this &1 mean?..."
--> This means all errors are redirected to the same file as non-error messages. You could also say :
15 8 * * * /tmp/ >>/tmp/cronjob.log 2>>/tmp/cronjob.log

"...How can I quit my script while the nohup job is actually running?..."
--> Don't know if i understood this question, the "/tmp/" script exit's automatically after executing the last line. Would in this case be after:
nohup /tmp/jobs/startjob &
and leaves the nohup job running.
