实现代码：

#!/bin/bash#ftime0=$(ll /root/hbshell/down.txt | awk '{print $7}')#ftime1=$(ll /root/hbshell/down.txt | awk '{print $7}')touch /root/hbshell/down.txt while :doif [[ /root/hbshell/down.txt -nt /root/hbshell/down_cp.txt ]]then user=rootpasswd=19871022host=192.168.1.202dir=/tmp/down/$(date +%Y%m%d)/$(date +%H%M)mkdir -p $dircd $dir#cat /root/hbshell/down.txt|sed -e 's#^ */##' -e 's# *##' -e 's#^[^a-zA-Z]*##'>/root/hbshell/zdown.txtcat /root/hbshell/down.txt|sed 's#^[^a-zA-Z]*##'>/root/hbshell/zdown.txt declare -a gg=($(cat /root/hbshell/zdown.txt))declare -i ifor ((i=0;i<${#gg[@]};i=$i+1))doecho ${gg[$i]}|grep -q "/"if echo $?| grep -q 0then tmpdir=$(echo ${gg[$i]} | sed 's#\(.*/\)\(.*$\)#\1#')mkdir -p ./$tmpdir fidone/usr/bin/ftp -i -in <<!open $host user $user $passwdbinmget $(echo ${gg[@]}) bye! declare -i jdeclare -i numnum=0for ((j=0;j<${#gg[@]};j=$j+1))doif [[ -f $(echo ${gg[$j]}) ]] then ls -l $(echo ${gg[$j]}) num=$num+1 else echo -e "\033[31m File ${gg[$j]} is not down!! \033[0m" fi doneecho "That Files all down total is $num "\cp /root/hbshell/down.txt /root/hbshell/down_cp.txtfidone

以上就是linux下自动化下载并检测ftp文件备份的实现代码，需要的朋友可以参考一下，如果有服务器权限，个人建议使用rsync
