一、需求：
寫一個shell腳本，檢查指定的shell腳本是否有語法錯誤，如有錯誤，首先顯示錯誤信息，而後提示用戶輸入q或者Q退出腳本，輸入其餘內容則直接用vim打開該shell腳本。

[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
