如何在Linux中获取磁盘的已用大小 [英] How to get disk's used size in linux

问题描述

在Redhat Linux中，如果未将磁盘安装到文件系统，我如何获得磁盘的总大小和使用的大小.

现在我可以使用命令获取总大小了
fdisk -l | grep磁盘

但是如果我使用命令
df
新磁盘未显示.因此我无法获得磁盘的已用大小.

In Redhat Linux, if the Disk is not mount to the filesystem how can i get the disk''s total size and used size.

Now I can get the total size use command
fdisk -l |grep Disk

But if I use command
df
the new disk is not show.so i can''t get the used size of the disk.

推荐答案

您可以使用此命令查看分区的大小:

You can use this command to see the size of partitions :

ls /proc/partitions

而且我猜想很难找到特定分区上的可用空间，除非已安装(安装)了相应的文件系统驱动程序.

希望对您有所帮助.

And I guess that its very difficult to find out how much space is free on a particular partition unless its corresponding filesystem driver were installed(mounted).

Hope it helps.

我认为df仅检查已挂载的文件系统.

I think that df only checks mounted filesystems.
