lsof meaning ‘LiSt Open Files’

‘LiSt Open Files’ is used to find out which files are open by which process.


In this directory, we know all the process.

for example:

If you take the AWS provider:

1)  Attach the volume:

   /dev/xvdf

2)  df -h

    Make sure that, volume was in the list.

3)  Create a directory:

    Mkdir  example

4)  Format (Format to this filesystem type ext4)

    Mkfs.ext4  example

5)  Cross verify, the  filesystem was properly formatted to        the ext4 type:

    Mount -a.

6)  Successfully Mounted.

7)  When you unmount:

    unmount  

   

(Make sure, no process was running on that /example inorder to check that,we have to use following command).

8) lsof | grep example

   (we can stop the services, related to that process and kill them using kill -15).

9) And then we can unmount the disk.

   (And we can detach the volume and delete the volume).
