1、需求：
写一个shell脚本，检查指定的shell脚本是否有语法错误，若有错误，首先显示错误信息，然后提示用户输入q或者Q退出脚本，输入其他内容则直接用vim打开该shell脚本。

[root@Dasoncheng sbin]# cat h.sh 
#!/bin/bash
sh -n $1 &>/tmp/err
if [ $? -eq 0 ];
then
    echo "The script is ok"
else
    cat /tmp/err
    read -p "Please input q/Q to exit , or others to edit it by vim: " n
    if [ "$n" == "q" ] || [ "$n" == "Q" ];
    then
        exit
    else
        vim $1
        exit
    fi
fi
