如果在shell脚本中有条件

Question

我有这样的shell脚本。

#!/bin/sh

s=$1      

pro=`ps -ef | grep $s | grep -v grep | grep -v test3.sh | wc -l`

 if [ $pro -eq 0 ] 
    then
            echo "Service $s is DOWN..."
            echo "Service $s is DOWN..." >> processlogs.txt
            echo "Starting Service $s..."
            echo "Starting Service $s..." >> processlogs.txt
            java -jar clientApplication.jar $s &

 else
            echo "Service $s is Running..."
            echo "Service $s is Running..." >> processlogs.txt

 fi

当我执行shell脚本，并且操作进入if条件时，它永远不会返回。它不断执行命令“java -jar clientApplication.jar $ s”。但在其他情况下没有问题。我的语法错误或任何逻辑错误。

谢谢...

Answer 1

你应该试试这个......

(java -jar clientApplication.jar $s &)

......而不是......

java -jar clientApplication.jar $s &

如果确实有效，请看看nohup
