ubuntu脚本有区别rename和bash

在ubuntu上写法有区别
使用
#!/bin/bash代替#!/bin/sh
否则if的时候会报
unexpected operator

rename的写法也不一样
使用
rename 's/aa/haohao/;' aa
代替
rename aa haohao aa
Bareword "DemoServer" not allowed while "strict subs" in use at (eval 1) line 1.

示例代码

#!/bin/bash

if [ $# -lt 3 ]
then
        echo "<Usage:  $0  App  Server  Servant>"
        exit 0
fi

APP=$1
SERVER=$2
SERVANT=$3

if [ "$SERVER" == "$SERVANT" ]
then
        echo "Error!(ServerName == ServantName)"
        exit -1
fi

if [ ! -d $APP/$SERVER ]
then
        echo "[mkdir: $APP/$SERVER]"
        mkdir -p $APP/$SERVER
fi

echo "[create server: $APP.$SERVER ...]"

make cleanall -C /usr/local/haohao/demo/

cp /usr/local/haohao/demo/* $APP/$SERVER/

cd $APP/$SERVER/
