Absolute path:

The path is written from the root directory /, for example: / usr/share/doc.

Relative path:

The path is not written from /, for example, from / usr/share/doc to / usr/share/man, it can be written as: cd.. / man this is how to write the relative path!

Common commands for working with directories

Next, let's take a look at some common commands for dealing with directories:

Ls: listing directories

Cd: switching directories

Pwd: displays the current directory

Mkdir: create a new directory

Rmdir: delete an empty directory

Cp: copy a file or directory

Rm: remove files or directories

Mv: move files and directories or modify the names of files and directories

You can use man [commands] to view the documentation for each command, such as man cp.

Ls (list directories)

In Linux systems, the ls command is probably the most frequently run.

Syntax:

[root@www ~] # ls [- aAdfFhilnrRSt] directory name

[root@www ~] # ls [--color= {never,auto,always}] directory name

[root@www ~] # ls [--full-time] directory name

Options and parameters:

-a: all files, along with hidden files (beginning with. Listed together (commonly used)

-d: list only the directory itself, not the file data in the directory (commonly used)

-l: long data string list, including file attributes, permissions and other data; (commonly used)

List all the files in the home directory (including attributes and hidden files)

[root@www ~] # ls-al

Cd (switch directories)

Cd is the abbreviation of Change Directory, which is the command used to change the working directory.

Syntax:

Cd [relative or absolute path]

# create a runoob directory using the mkdir command

[root@www ~] # mkdir runoob

# change to the runoob directory using an absolute path

[root@www ~] # cd / root/runoob/

# change to the runoob directory using a relative path

[root@www ~] # cd. / runoob/

Go back to your home directory, that is, / root

[root@www runoob] # cd ~

It means to go to the current one-level directory, that is, the one-level directory of / root

[root@www] # cd.

Next, you should be able to understand the cd command a few more times.

Pwd (shows the directory where it is currently located)

Pwd is an acronym for Print Working Directory, that is, a command that displays the current directory.

[root@www ~] # pwd [- P]

Options and parameters:

-P: shows the exact path instead of using the link path.

Example: simply shows the current working directory:

[root@www ~] # pwd

/ root
