Linux ‘ll’ Command Purpose Explained

The ll command in Linux is commonly used to display detailed information of files and subdirectories in the current directory. In fact, the ll command is just an alias for the ls -l command, and both provide the same functionality.

The purpose of the ‘ls’ command is to list all files and subdirectories in the current directory, displaying detailed information such as file permissions, owner, group, size, creation time, etc. This detailed information helps users to better understand the files in the current directory, making it easier to manage and view file properties.

Here is an example of using the ll command:

$ ll

After executing the above command, the system will display detailed information for all files and subdirectories in the current directory.

Please note that the ll command is not a default command provided by the Linux system, but rather an alias predefined by some Linux distributions (such as Ubuntu). If your system does not recognize the ll command, you can achieve the same functionality by using the ls -l command.
