我平时使用 fishshell, 为了精确方便的杀进程，写了个脚本函数
function pk --description 'kill processes containg a pattern'

psg $pid | ag $argv[1] # list the details of the process need to be sudo kill
read -n 1 -p 'echo "Use sudo to kill it? [Y/n]: "' -l arg
if test "$arg" = "" -o "$arg" = "y" -o "$arg" = " "
sudo kill -9 $pid
