这里相关的转账模块         可以参考这写一下  上面没写有些麻烦

forwardmoney(){
    	read -p "输入转账账号" new_name
    	echo $new_name
    	if awk -v account=$new_name '{if($1==new_name)print $1}' ./info.txt&>/dev/nul
    l	then
    		read -p "输入转账金额" for_money
    		money1=`awk -v account=$account '{if($1==account)print $3}' ./info.tx
    t`		if [ $money1 -lt $for_money ]
    		then
    			echo "余额不足！"
    		else
    			all_money1=$(($money1-$for_money))
    			sed -i "/$account/s/$money1/$all_money1/" ./info.txt
    			money2=`awk -v account=$new_name '{if($1==account)print $3}' 
    ./info.txt`			all_money2=$(($money2+$for_money))
    			sed -i "/$new_name/s/$money2/$all_money2/" ./info.txt
    			echo "转账成功"
    			query
    		fi
    	else
