实现代码：

#!/bin/bash #ftime0=$(ll /root/hbshell/down.txt | awk '{print $7}') #ftime1=$(ll /root/hbshell/down.txt | awk '{print $7}') touch /root/hbshell/down.txt while : do if [[ /root/hbshell/down.txt -nt /root/hbshell/down_cp.txt ]] then user=root passwd=19871022 host=192.168.1.202 dir=/tmp/down/$(date +%Y%m%d)/$(date +%H%M) mkdir -p $dir cd $dir #cat /root/hbshell/down.txt|sed -e 's#^ */##' -e 's# *##' -e 's#^[^a-zA-Z]*##'>/root/hbshell/zdown.txt cat /root/hbshell/down.txt|sed 's#^[^a-zA-Z]*##'>/root/hbshell/zdown.txt declare -a gg=($(cat /root/hbshell/zdown.txt)) declare -i i for ((i=0;i<${#gg[@]};i=$i+1)) do echo ${gg[$i]}|grep -q "/" if echo $?| grep -q 0 then tmpdir=$(echo ${gg[$i]} | sed 's#(.*/)(.*$)#1#') mkdir -p ./$tmpdir fi done /usr/bin/ftp -i -in <<! open $host user $user $passwd bin mget $(echo ${gg[@]}) bye ! declare -i j declare -i num num=0 for ((j=0;j<${#gg[@]};j=$j+1)) do if [[ -f $(echo ${gg[$j]}) ]] then ls -l $(echo ${gg[$j]}) num=$num+1 else echo -e "33[31m File ${gg[$j]} is not down!! 33[0m" fi done echo "That Files all down total is $num " cp /root/hbshell/down.txt /root/hbshell/down_cp.txt fi done

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
