How to kill all specific java processes-CodePudding

I have following search result coming from netstat:

netstat -nap | grep java | grep :::300*
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp6       0      0 :::30008                :::*                    LISTEN      81159/java          
tcp6       0      0 :::30010                :::*                    LISTEN      81164/java          
tcp6       0      0 :::30001                :::*                    LISTEN      81155/java          
tcp6       0      0 :::30002                :::*                    LISTEN      81162/java          
tcp6       0      0 :::30003                :::*                    LISTEN      81156/java          
tcp6       0      0 :::30004                :::*                    LISTEN      81161/java          
tcp6       0      0 :::30005                :::*                    LISTEN      81158/java          
tcp6       0      0 :::30006                :::*                    LISTEN      81157/java          
tcp6       0      0 :::30007                :::*                    LISTEN      81160/java

now I need to iterate over that result, get the process id ad kill it. How can I do it ?

CodePudding user response：

PIDS=( $(netstat -nap | grep java | grep :::300*| awk '{print $6}' | cut -d "\/" -f2 | xargs) ); for p in "${PIDS[@]}"; do kill -9 ${p}; done i think you can do like this but i think can be more easy way

CodePudding user response：

netstat -nap | grep java | grep :::300* | while read -r line; do
  sed -En '/tcp/s~.*(\t|  )([^/]*).*~kill -9 \2~pe' <<< "$line"
done
