script for killing all ftpd sessions

[Deepu Chakravarty]

I have many ftp sessions in my server (rp7420 HPUX 11.11). I need to kill all these ftpd sessions periodically. I am using following command to kill these sessions:
kill -9 ` ps -ef|grep ftpd|awk '{print $2}'`
. This line I have added in one file and running the file with a cron job. But the cron job is itself killing the first ftpd job it is finding and not the other ftp sessions.
How it can be achieved? Thanks in advance.

Add -9 if it fails:
kill $(UNIX95=EXTENDED_PS ps -C ftpd -opid=)
