           $2：服务器IP

           $3：用户名

           $4：密码

#/bin/bash

DIRCTORY=$1

is_empty_dir(){
	return `ls -A $DIRCTORY | wc -w`
}

put_file(){
	exec 6>&1 1>$1/../tmp.txt
	ftp -nv<<-EOF
	open $2
	user $3 $4
	passive
	binary 
	hash 
	cd UP/ 
	lcd $DIRCTORY
	prompt  
	mput *	
	close
	bye
	EOF
	
	exec 1>&6
	exec 6>&-
	if grep -q "Transfer complete" $1/../tmp.txt;then
		echo "commit to ftp successfully" >> $1/../log.txt
		rm -rf $DIRCTORY*.*
	else
		echo "commit to ftp failure!" >> $1/../log.txt
	fi
	rm -rf $1/../tmp.txt
	sleep 60
	echo "commit to ftp successfully"
}


#上传文件
