Linux file and directory management
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
