shell執行的目的是根據我輸入的字串找到對應的行程殺死
這樣執行時回傳結果為
[root@localhost new]# sh deploy1.sh -M asfasfa
line:26
但是如果我找自己運行的程式時，此時程式還未運行，但還是獲取到了未知的pid
[root@localhost new]# sh deploy1.sh -M com.test.auto.main.AutoMain
line:26 24685 24686
deploy1.sh: line 27: [: 24685: unary operator expected
執行以下命令可以看出，我的程式的確沒有運行
[root@localhost new]# ps -ef|grep com.test.auto.main.AutoMain |grep -v grep | awk '{print $2}' | awk -F"/" '{ print $1 }'
[root@localhost new]# 這是什么原因引起的呢？

我整理了一下代碼，發現只要字串從外面指定并生效，就一定會出現此問題
[root@xd-vdn-liveback-01 yuewendong]# sh deploy3.sh -M aasgsdgsr
