How can the number of free inodes on a Linux system be determined?

To determine the number of free inodes in a Linux system, the df command with the -i (inode) option is used. It displays information about file systems, including the total number of inodes, used, and free.

Example command:

df -i

The output will contain columns where you can see the number of free inodes in the file system. This is useful when the file system is not full in terms of volume but may run out of inodes (for example, when there are many small files).
