我正在尝试编写一个别名来终止所有正在运行的 php 进程。这是我在~/.bash_profile
alias killphp="ps aux | g [p]hp | awk '{print $3}' | xargs kill -9"
如果我按原样输入而不使用别名,这个命令就可以正常工作。但如果我只是运行,killphp
就会出现这种奇怪的情况:
grep: warning: recursive search of stdin
kill: illegal process id: (standard
kill: illegal process id: input):2:abdullah
kill: illegal process id: 10.9
kill: illegal process id: 0.2
kill: 2496576: No such process
kill: 20460: No such process
kill: illegal process id: ??
kill: illegal process id: S
kill: illegal process id: 7:14AM
kill: illegal process id: 0:00.28
kill: illegal process id: /usr/local/Cellar/php54/5.4.28/bin/php
kill: illegal process id: /Users/abdullah/dev/php/smartTaxi/app/console
kill: illegal process id: bcc:resque:worker-start
kill: illegal process id: -f
kill: illegal process id: request_queue
kill: illegal process id: --env=dev
kill: illegal process id: (standard
kill: illegal process id: input):3:abdullah
kill: illegal process id: 6.0
kill: illegal process id: 0.1
kill: 2486972: No such process
kill: 9708: No such process
kill: illegal process id: ??
kill: illegal process id: S
kill: illegal process id: 7:14AM
kill: illegal process id: 0:00.08
kill: illegal process id: php
kill: illegal process id: /Users/abdullah/dev/php/smartTaxi/app/../vendor/chrisboulton/php-resque/resque.php
如果我运行type killphp
我会得到这个:
killphp is aliased to `ps aux | g [p]hp | awk '{print }' | xargs kill -9'
因此,显然$3
awk 的参数已经消失!我该如何摆脱它?我尝试过/$3
,$$3
但都不起作用。

您最好使用pkill
。但要解决您的问题,请killphp
通过将其放入您的配置文件中来创建一个 bash 函数而不是别名。
killphp() {
ps aux | g [p]hp | awk '{print $3}' | xargs kill -9
}
然后您就可以像别名一样使用它:
killphp
$
您可以通过编写来逃避\$
,但使用函数时您不必担心引用。
