How to use Linux commands to create or delete folders?

PHP editor Youzi will introduce you in detail how to use commands to create or delete folders in Linux systems. In Linux, use the mkdir command to create a new directory, and use the rm command to delete a directory. These two commands are the most basic and commonly used folder operation commands in Linux systems. Mastering them can help you manage the file system more efficiently. Next, we will explain how to use these two commands one by one, so that you can easily master the skills of creating or deleting folders.

What is a Linux system?

Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance. It can run major UNIX software tools, applications and network protocols. It supports 32-bit and 64-bit hardware.

1. Linux delete folder command

Deleting a directory in Linux is very simple. Many people are still accustomed to using rmdir. However, once the directory is not empty, they will fall into deep distress. Now use the rm -rf command.

Just rm directly, but you need to add two parameters -rf, namely: rm -rf directory name

Note: Be extra careful when using rm -rf. Linux does not have a recycle bin.

1. Delete directories and files rm(remove)

Function description: Delete files or directories.

Syntax: rm [-dfirv][--help][--version][file or directory]

Supplementary instructions: Execute the rm command to delete files or directories. If you want to delete a directory, you must add the parameter "-r", otherwise only the files will be deleted by default.

parameter:

• -d or –directory Directly delete the hard link data of the directory to be deleted to 0 and delete the directory.
• -f or –force Forcefully delete files or directories.
• -i or –interactive Ask the user before deleting existing files or directories.
• -r or -R or –recursive Recursive processing, processing all files and subdirectories in the specified directory together.
• -v or –verbose Display the instruction execution process.

2. Delete folder:

de>rm -rf fileNamede>

Delete folder instance:

rm -rf /var/log/httpd/access

The /var/log/httpd/access directory and all files and folders under it will be deleted.

3. Delete files:

de>rm -f fileNamede>

2. Linux add file command

1. Create directories: mkdir(make directories)

Syntax: mkdir [-p][--help][--version][-m ][Directory Name]

Note: mkdir can create a directory and set the permissions of the directory at the same time.

parameter:

• -m or –mode Set the directory permissions when creating the directory.
• -p or –parents If the upper-level directory of the directory to be created has not been created yet, the upper-level directory will be created together.

Example: mkdir test

2. Create file touch

Function Description: Change file or directory time

Syntax: touch [-acfm][-d ][-r ][-t ] [--help] [--version][file or directory] or touch [-acfm][--help][--version][date and time][file or directory]

Note: Use the touch command to change the date and time of a file or directory, including access time and change time.

parameter:

• -a or –time=atime or –time=access or –time=use Change only the access time.
• -c or –no-create Do not create any files.
• -d Use the specified date and time instead of the current time.
• -f This parameter will be ignored and will not be processed. It is only responsible for solving the compatibility problem of the BSD version of the touch command.
• -m or –time=mtime or –time=modify Only change the change time.
• -r Set the date and time of the specified file or directory to be the same as the date and time of the reference file or directory.
• -t Use the specified date and time instead of the current time.

Example: touch test.txt

Note: There is no file suffix name to distinguish file types under Linux. The system file types are only executable files and non-executable files.
