How to list files by inode number using the ls command in Linux?

To list files by inode number using the ls command in Linux, you can use the -i option. This will display the inode number of each file or directory along with its name. Here is an example command:

ls -i

This will display a list of files and directories in the current directory, along with their inode numbers.

You can also combine this command with other options such as -l to display more detailed information about each file or directory, or -a to show hidden files as well.

Note that inode numbers are unique identifiers assigned to each file or directory on a Linux file system. They are used by the file system to keep track of the file’s metadata, such as its size, permissions, and location on the disk. In general, inode numbers are not used by users for file management, but they can be useful for advanced troubleshooting or debugging purposes.
