I am having a problem updating the nessus plugin which I just got from http://www.tifaware.com/perl/update-nessus-plugins/, I did chmod 777 on the file then ran the following command below:   #./nessus-update-plugins -i /usr/local/soft_download/update-nessus-plugins - bs $fetch_cmd not set in ./nessus-update-plugins - aborting   If someone can help me out here as to why I am getting the following error msg I would appreciate it.   thanks,   Puneet
