crontab -l > somefile

Then edit somefile and remove or add any lines you wish

When you are finished editing, type:

crontab somefile

To activate the new crontab.  Some unixes allow

crontab -e

to edit a crontab file.  Use

man crontab

to see what options are available.

i need to do this via crontab options, if any, i dont' want to do this manually.
crontab -e is the closest you will come.  Crontab files are simple text files, completely unstructured.  Look for a third parts utility of you wish to have a GUI, for example.
crontab -l | head -1 | crontab
