这是一点点复制,所以如果你有一个500GB的硬盘,即使有千兆以太网也需要很长时间

如果你gzip一个空文件,它会变成20个字节。我做的一些备份检查检查文件是否大于零大小(-s标志),但这在这里并不好。我确定有人比我有更好的支票吗?在检查文件的大小之前,不检查文件是否存在。

linux命令:BACKUP_FILE_SIZE=`eval ls -l ${BACKUP_FILE} | awk {'print $5'}`; if [ $BACKUP_FILE_SIZE -le 20 ]; then echo "its empty"; else echo "its not empty"; fi fi empty"; not "its echo else empty"; "its echo then ]; 20 -le $BACKUP_FILE_SIZE [ if $5'}`; {'print awk | ${BACKUP_FILE} -l ls BACKUP_FILE_SIZE=`eval BACKUP_FILE_SIZE=`eval ls -l ${BACKUP_FILE} | awk {'print $5'}`; if [ $BACKUP_FILE_SIZE -le 20 ]; then echo "its empty"; else echo "its not empty"; firootopen.com

还解析了符号链接,显示链接目标的完整路径

linux命令:BASEDIR=$(dirname $(readlink -f $0)) $0)) -f $(readlink BASEDIR=$(dirname BASEDIR=$(dirname $(readlink -f $0))rootopen.com

将目录结构从/home/复制到/backup /home(注意目标没有尾随斜杠)

linux命令:BEGIN=`date`; rsync -avxW /home/ /backups/home ; echo "Begin time: $BEGIN" ; echo "End time..: `date`" `date`" time..: "End echo ; $BEGIN" time: "Begin echo ; /backups/home /home/ -avxW rsync BEGIN=`date`; BEGIN=`date`; rsync -avxW /home/ /backups/home ; echo "Begin time: $BEGIN" ; echo "End time..: `date`"rootopen.com

当您使用此方法阻塞主机时,主机在网络中不能做任何事情。 应用于网络防火墙或网关上

linux命令:Blocking ip: arp -s ip_of_host 0, Unblocking ip: arp -d ip_blocked ip_blocked -d arp ip: Unblocking 0, ip_of_host -s arp ip: Blocking Blocking ip: arp -s ip_of_host 0, Unblocking ip: arp -d ip_blockedrootopen.com
