do you mean the syntax? you can use rm [log name]
or rm * to remove all logs file. But you must know first where the location of the log.

You have a problem.  You have to know how the process is accessing the log.  If it keeps the file open, if you remove it, the file will still grow but only lsof will see it.

If it opens and closes the file each time, you remove it and it may be recreated.

If you try to reset the EOF to 0, the application may continue to write to what it thinks is the old EOF, so you may nuke the contents up to that EOF.

Or it may just start writing at the beginning.
