[居然没有 shellscript 节点]随手写了一个小脚本，帮助你 kill 进程。

使用方式：mykill <进程名或pid>

如果参数为纯数字，如 1234 ，则会被当成是pid。mykill会直接询问你是否要kill到这个进程。
如果参数不为纯数字，比如 qq，则mykill会自动匹配包含这个字符串的进程。如果包含这个字符串的进程只有一个，那么mykill会询问是否kill掉这个进程。如果包含这个字符串的进程有多个，则会打印一个进程列表。

>> mykill 10150 #参数为pid
kill 10150 /Applications/QQ.app/Contents/MacOS/QQ? [y/n]

>> mykill qq #参数为进程名，只match到一个结果
kill 10150 /Applications/QQ.app/Contents/MacOS/QQ? [y/n]

>> mykill sh #参数为进程名，match到多个结果
22340 brambles /bin/bash
10180 brambles -zsh
22341 brambles /bin/bash
43369 brambles -zsh
43262 brambles /bin/bash
7747 brambles -zsh
matched 6 processes!

>> mykill abc #没有match到结果
no thing matched!

=====================以下是脚本代码====================
将一下代码保存到一个文件里面，并给文件执行权限就行了。

#!/bin/bash

if [[ $1 =~ ^[0-9]+$ ]]
then
    p_l=$(ps aux | awk -v pid="$1" 'NR > 1 && $2 == pid {print  $2, $1, $11}')
else
    p_l=$(ps aux | awk -v pname="$1" 'NR > 1 && tolower($11) ~ tolower(pname) {print  $2, $1, $11}')
fi

l_n=$(echo "${p_l}" | grep -v ^\s*$ |wc -l)
l_n=$(echo ${l_n})

if [ ${l_n} == 0 ]
then
    echo "no thing matched!"
elif [ ${l_n} == 1 ]
then
    p_pid=$(echo "${p_l}"| awk '{print $1}')
    p_name=$(echo "${p_l}"| awk '{print $3}')
    read -p "kill ${p_pid} ${p_name}? [y/n]" -n 1 -r
    if [[ $REPLY =~ ^[Yy]$ ]]
    then
        kill -9 ${p_pid}
    fi
    echo

else
    echo "${p_l}"
    echo "matched ${l_n} processes!"
fi

@bramblex killall没有这么不济吧，-r可以用正则式来匹配。要是要求按参数而不是命令本身进行匹配的话，那的确不如自己造的顺手。
Usage: killall [-Z CONTEXT] [-u USER] [ -eIgiqrvw ] [ -SIGNAL ] NAME...
killall -l, --list
killall -V, --version

-e,--exact require exact match for very long names
-I,--ignore-case case insensitive process name match
-g,--process-group kill process group instead of process
-i,--interactive ask for confirmation before killing
-l,--list list all known signal names
-q,--quiet don't print complaints
-r,--regexp interpret NAME as an extended regular expression
-s,--signal SIGNAL send this signal instead of SIGTERM
-u,--user USER kill only process(es) running as USER
-v,--verbose report if the signal was successfully sent
-V,--version display version information
-w,--wait wait for processes to die
-Z,--context REGEXP kill only process(es) having context
(must precede other arguments)
