rsync大括号扩展洞察力

  • 772

我想将我的 ubuntu 14.04 安装与外部磁盘中的目录同步。

实际上我是从扩展驱动器启动的，我想在我安装的内部驱动器中制作我的 ubuntu 14.04 发行版的部分副本/media/kenn/c2d1b866/

挂载的目标目录/mnt/RESTORE/backup_14.04.5

我尝试了许多rsync命令的组合，例如

sudo rsync -avr /media/kenn/c2d1b866/{bin/,sbin/,usr/,opt/,lib/,var/,etc/,srv/,libx32/,lib64/,run/,boot/,proc/,sys/,dev/} /mnt/RESTORE/backup_14.04.5

sudo rsync -avr /media/kenn/c2d1b866/{bin/,sbin/,usr/,opt/,lib/,var/,etc/,srv/,libx32/,lib64/,run/,boot/,proc/,sys/,dev/} /mnt/RESTORE/backup_14.04.5/

sudo rsync -avr /media/kenn/c2d1b866/{"bin/","sbin/","usr/","opt/","lib/","var/","etc/","srv/","libx32/","lib64/","run/","boot/","proc/","sys/","dev/"} /mnt/RESTORE/backup_14.04.5

还有很多其他的，但我失败了，因为大括号扩展没有像我预期的那样工作。他们将大括号目录中的所有文件复制到/mnt/RESTORE/backup_14.04.5中，我的意思是未在其中创建的根目录backup_14.04.5

我怎样才能复制那些bin/,sbin/,usr/,opt/,lib/,var/,etc/,srv/,libx32/,lib64/,run/,boot/,proc/,sys/,dev/

在/media/kenn/c2d1b866/到/mnt/RESTORE/backup_14.04.5？

    他们将大括号目录中的所有文件复制到/mnt/RESTORE/backup_14.04.5

    这就是rsync源路径有尾部斜杠时的行为/。来自man rsync：

    A  trailing slash on the source changes this behavior to avoid creating
an additional directory level at the destination.  You can think  of  a
trailing / on a source as meaning "copy the contents of this directory"
as opposed to "copy the directory by  name",  but  in  both  cases  the
attributes   of   the  containing  directory  are  transferred  to  the
containing directory on the destination.

    要复制目录，请省略/：

    sudo rsync -avr /media/kenn/c2d1b866/{bin,sbin,usr,opt,lib,var,etc,srv,libx32,lib64,run,boot,proc,sys,dev} /mnt/RESTORE/backup_14.04.5
