keyword='ssh-agent'
IFS_OLD=$IFS
IFS=$'\n'
for pid in $(ps -e | grep $keyword | awk '{print $1}')
do
    if ps -f $pid &> /dev/null ; then
        echo "kill $pid"
        kill $pid
    fi
done
IFS=$IFS_OLD

查看目录下的文件全路径

ls | gawk '{ "pwd" | getline dir;  print dir"/"$0  }'

docker container ls -a | gawk 'NR>1 {printf " " $1}' | xargs docker container rm
