Yup but the cat process can be avoided:

(crontab -l; echo "00 1 * * * /monitor_file_system") | crontab

Is there way to JUST append a new line to crontab by program, so that
the other already running cornjobs will function without any
interrupt?

Thanks,

- running cronjobs are not interrupted by changing the crontab.
- You can add lines to Your /var/spool/cron/crontabs/<user> file with
any programm, but You have to tell the cron-daemon, that the
crontab has changed. This is done by the crontab command.
