This will work if you want to count number of netcat processes active at any given time. For duration, fire ps -aef twice, once at beginning and once at the end of duration. GET the PIDs, and then count PIDs for second ps which were not there in first ps. For example Time T It gives you 4445,4446,4447 Time T+D It gives you 4447,4449,4450 So 4447 was there beforehand, so you ignore that, and your result is 2 _______________________________________________ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
