查找端口被哪个进程占用

 

take 5333 port for example.

 

incore1:/u/ainet/hui-# cat tex.sh.sh
#!/usr/bin/ksh

ps -ef | grep -v grep | while read X PID X
do
    #echo $PID

    if pfiles $PID | grep 5333 > /dev/null 2>&1
    then
        echo $PID
    else
    :
    fi

done

incore1:/u/ainet/hui-# cat tex.sh
#!/usr/bin/ksh

rm -f tex.log

ps -ef | grep -w TestConnection | grep -v grep | read X PID X
echo $PID

integer x=1

while(true)
do
  echo -n "$x " | tee -a tex.log

  ps -ef | grep -w TestConnection | grep -v grep | while read X PID X
  do

    pfiles $PID | grep AF | grep sockname | grep -v "0/.0/.0/.0" | while read X X X X PORT
    do
      netstat -an |grep $PORT | tee -a tex.log
    done

    sleep 1
    x=$x+1

  done
done
