PID variable

Hi all, How i can retrive the current pid value of freeradius in Shell script. I wanted to create one shell script to run in linux corn commond. because our database is very slow and always radius is going to crashed when it receives more than 1000 request. so my script will check if the radius is crashed it will start automatically using cron. Is anyone have good logic to auto restart radius when it will be crashed? -------- Yours, Abdul Lateef Computer Programmer HATIF COM Mob: +974 - 5405022 Tel: +974 - 4883068 ICQ: 276994704 YM!: abdul_zu Fax: +974 - 4883063 Doha Qatar http://www.hatif.com __________________________________ Yahoo!
