Linux basics 35


For the file big.txt located in /cxldata/ folder, who is the owner and group?

Why its answer is root root? what is a root?. I understand / is a root. Can you explain briefly what is it exactly?


Yes “/” is root directory i.e. the top most directory.
But there is a user with name root too who is the superadministrator.
Take a look at ls -l /cxldata/big.txt, you will know who is the owner of this file.


Thank you for the assistance.

Using chmod , give it permissions such that the owner of the file should be able to modify. Everyone should be able to execute but no one other than owner can modify the file.

Q1) I am unable to execute the exact code, where Am I lacking?


I did it on my own, sorry for bothering you.
