[CP]Linux根據程序名稱Kill多個程序

經常需要Kill多個程序，這些程序包含共同的關鍵字，可以用一條指令Kill掉它們。

ps aux | grep “cmd-test.php” |grep -v grep| cut -c 9-15 | xargs kill -9

管道符“|”用來隔開兩個指令，管道符左邊指令的輸出會作為管道符右邊指令的輸入。下面說說用管道符聯接起來的幾個指令：

“ps aux” 檢視所有程序的指令。這時檢索出的程序将作為下一條指令grep “common”的輸入。

“grep “common” 選出所有含有關鍵字”common”的程序。

“cut -c 9-15” 截取輸入行的第9個字元到第15個字元，而這正好是程序号PID。

“xargs kill –9” 中的xargs指令是用來把前面指令的輸出結果（PID）作為”kill –9”指令的參數，并執行該指令。”kill –9” 會強行殺掉指定程序。

項目執行個體：

項目中監控兩個程序，如果程序丢失，則自動啟動，另外把這個shell腳本配置在linux下面的crontab，定時執行即可！

#!/bin/bash
pcount=$(ps -fe|grep cmd-test.php |grep -v grep|wc -l|awk '{print $1}')
if [ $pcount -eq  ]
then
        echo "running two process"
else
        echo "process != 2,then need to restart process"
        ps aux | grep "cmd-test.php" |grep -v grep| cut -c - | xargs kill -
        echo "process kill over,starting the process"
        nohup /usr/local/php/bin/php /data1/htdocs/xxx/bin/cmd-test.php query/execute &
