linuxmkdir只读文件

Introduction

Linux is an open-source operating system that enables its users to create, modify and delete files as per their preferences and requirements. Linux file management commands, including the mkdir command, facilitate managing directories or folders in the system. In this article, we will be discussing how to create read-only folders using the mkdir command in Linux.

Creating Read-only Folders Using the mkdir Command

The mkdir command in Linux is used to create new directories. When creating read-only folders, we use the chmod command to modify the permissions of the folder. The chmod command is used to modify the file and directory permissions in Linux. It is an essential command that is used to control access to files and directories.

The syntax of using the chmod command is:

chmod options permissions file/folder

The options can be:

• u - user
• g - group
• o - others

The permissions can be:

• r - read
• w - write
• x - execute

Using the chmod command with the options and permissions mentioned above can make a directory read-only. For instance, to make a directory named 'examples' read-only, the command would be:

mkdir examples
chmod 555 examples

The '555' in the command above is the code that sets the permissions to be read-only for everyone.

Benefits of Using Read-Only Folders

Using read-only folders comes with several benefits, for instance:

• Security: Read-only folders protect files and directories from being deleted or modified by unauthorized users.
• Data integrity: Read-only folders prevent the accidental deletion, modification or corruption of files and directories.
• Backup: Read-only folders make it easier to backup files and directories without worrying about accidental changes or deletion.

In conclusion, the mkdir command in Linux is essential when creating read-only folders. Using read-only folders ensures the security and integrity of files and directories. By understanding the chmod command and how to use it to modify directory permissions, creating read-only folders becomes an easy process.
