Clear progress into CLOSE_WAIT

netstat -nap |grep :8009|grep CLOSE_WAIT | awk '{print $7}'|awk -F"\/" '{print $1}' |awk '!a[$1]++'  |xargs kill

Filtered port 8009,

CLOSE_WAIT filtered out of state,

The first seven to take the results of that process information, the format is such that 12568 / httpd,

Then repeat the process of removing the numbers,

Finally xargs into the kill command to kill the corresponding process.
