Interviewer: Lets say there is a partition of 100GB. When i
tried to create a file using touch command, under any
directory, it was unable to create the file- '100% full
disk space'. I calculated the size of each and every
directory on that partition mannually by adding each file
size & in came out to be total size 50GB. Then where is the
remaining 50GB ? why it is showing disk space 100% full
in 'df -h' command?
