自动化的Bash脚本-找不到命令

Question

我的.bash_profile中有以下内容：

k9 () { for A in $(ps -A | grep $* | sed 's/^\([A-Za-z0-9]*\).*/\1/' ; ) ; do "kill -9  $A"; done  }

脚本应该grep在命令行S*中输入的var，获取PID，并对每个PID执行kill -9。但我得到的却是：

Machine:~ mach$ k1 Chromium
-bash: kill -9  81922: command not found
-bash: kill -9  82009: command not found
-bash: kill -9  82423: command not found
-bash: kill -9  82424: command not found
-bash: kill -9  82560: command not found
-bash: kill -9  82561: command not found
-bash: kill -9  82563: command not found
-bash: kill -9  82608: command not found
-bash: kill -9  85243: command not found
-bash: kill -9  85248: command not found
-bash: kill -9  85321: command not found

提前感谢！
