What does the 'mkdir' command do?

The mkdir command is used in Linux and Unix-like operating systems to create new directories (folders).

Key Points:

• Basic Usage: You can create a single directory by specifying its name, e.g., mkdir new_directory.
• Multiple Directories: You can create multiple directories at once by listing them, e.g., mkdir dir1 dir2 dir3.
• Nested Directories: With the -p option, you can create nested directories in one command, e.g., mkdir -p parent/child/grandchild.
• Permissions: You can set permissions at the time of creation using the -m option, e.g., mkdir -m 755 new_directory.

Overall, mkdir is a fundamental command for organizing files and directories in the file system. If you have more questions or need examples, feel free to ask!
