How to list the inodes of directories on a Linux machine.

It is possible with ls to list only directories on a Linux system, but you can also list the inode values of the directories on a Linux system.

The example below shows how this is done. The -i parameter shows the 📂 inodes value.

┌──(john㉿DESKTOP-PF01IEE)-[~]
└─$ ls -ldi -- */
  150 drwxr-xr-x 2 john john 4096 May 12 10:50 Documents/
43846 drwxr-xr-x 3 john john 4096 Apr 19 10:24 Downloads/

This is how to print what filesystem type a folder is housed on.

┌──(john㉿DESKTOP-PF01IEE)-[~]
└─$ df -PTh Documents/ | awk ' NR==2 {print $2}'
ext4

That could also be very useful indeed.

This is another way to print the inode value of a directory on a Linux system.

┌──(john㉿DESKTOP-PF01IEE)-[~]
└─$ stat Downloads/ | awk 'NR==3 {printf $4}'
43846

And yet another way to print the filesystem type a directory is located on.

┌──(john㉿DESKTOP-PF01IEE)-[~]
└─$ df -T | awk 'NR==2 {printf $2}'
ext4

This shows how flexible Linux is, you can get almost any information you desire from your Linux machine.
