它会把符号链接所指向的文件占用磁盘空间的大小也统计进来。帮助文档是这样解释的:Dereference symbolic links(show the disk space used by the file or directory that the link points to instead of the space used by the link)。 我们在download目录下创建一个符号链接,指向本目录下的一个文件。我们看到上面...
Dereference symbolic links(show the disk space used by the file or directory that the link points to instead of the space used by the link)。 我们在demo3目录下创建一个符号链接,指向本目录下的一个文件。我们看到上面图片中显示的操作结果,当使用-L选项时,du会把符号链接所指向的文件的大小也统计到...
七、du -L：这个选项主要是针对符号链接。它会把符号链接所指向的文件占用磁盘空间的大小也统计进来。帮助文档是这样解释的：Dereference symbolic links(show the disk space used by the file or directory that the link points to instead of the space used by the link)。我们在download目录下创建...

The total displayed for any given directory is the space used by the directoryitself and any subdirectories. du: without seeing the details of the various subdirectories To find out the total amount of disk space used without seeing the details of the various subdirectories, use...

By default, the du command shows the disk space used by the directory or file`. To find the apparent size of a directory, use the --apparent-size option. The “apparent size” of a file is how much data is actually in the file.(文件中实际的数据量) apparent size & disk usage size...
dentry对象保存在slab cache里,这个也叫directory entry cache(or dcahce)。这样就可以快速的寻找一个文件。一个或多个dentry会关联到一个inode上,比如硬链接(hard link)。 路径名查找(pathname lookup) 当我们使用open(), mkdir()等系统调用的时候,需要根据路径名找出对应的VFS对象(inode, dentry等),这个过程就...
If the error message "open: No such file or directory while opening /dev/vdb1" is returned, an incorrect partition is specified. Run parted to view disk partitions. If the file system format is xfs, run the following command (/mnt/sdc is the mount point of /dev/vdb1. Change it based...
You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, and work with swap space. 在第三章中,我们讨论了内核提供的一些顶层磁盘设备。 在本章中,我们将详细讨论如何在Linux系统中使用磁盘。 您将学习如何分区磁盘,创建和维护磁盘分区内的文件系统,并处理...
