Hey there! I'm new to UNIX / Linux and have some problems. I know that I can kill processes in unix, but I don't know how. I know the kill command, but how do I list running processes??? Whats PID ??? Please help. Thx and happy new year. Wolfgang

ps -ef will output a list of currently running processes. Column 2 of the output is the PID. To kill off a running process, forcefully, execute the command kill -9 PID ( where PID is an integer you got from the ps command ). Here is a script I wrote to kill off processes by name -----------8<----cut here---8<------- #!/bin/ksh if [ $# -gt 0 ]; then process_name=$1 ps_count=`ps -ef | grep -v 'grep' | grep -v 'kill' | grep -i -c $process_name` echo "Process count: $ps_count" set -A array_name `ps -ef | grep -i $process_name | grep -v 'grep' | grep -v 'kill' | awk '{print $2}' | sort -u` print "ps -ef | grep -i $process_name | grep -v 'grep' | grep -v 'kill' | awk '{print \$2 \$8}' | sort -u -n" print "${array_name[*]}" kill_count=0 while [ $kill_count -lt $ps_count ] do kill -9 ${array_name[$kill_count]} # print "kill -15 ${array_name[$kill_count]}" ((kill_count=kill_count+1)) done else print "Usage: $0 process_name" print "" fi

Thanks for the prompt answer. Happy new year. Wolfgang

I use kill -9 PID to kill a specific user. It works fine, but when any other user log on the same modem, although he is connected, he cannot browse the net. Mine is dial-in and proxy server where users dial via there telephone lines. I'm using Rocekt ports and external modem. I have to reboot the server to make it work again. Help me???????????
