".." Represents the directory at the next level, or you can use ".. /"

"~" represents the user's own host directory

"/" is at the top of the Linux file system tree, which we call the root of the Linux file system, and it is the entrance to the Linux file system.

All directories, files, and devices are under /, which is the only directory at the top of the Linux file system.

It is generally recommended that there is only a directory under the root directory, and do not store files directly; the root directory is the first partition loaded by the system when the linux system starts, so all the files used during startup should be placed in this partition.

The five subdirectories of / etc, / bin, / dev, / lib and / sbin should be connected to the root directory and should not become a partition independently.
