permission to copy a file and write
I m a little confused I have mounted a volume using NFS from the server with permissions 755 (drwxr-xr-x). I can get inside this directory and cp the file to the required destination and then edit them . But inside the main source directory I can't do anyting . So was wondering which permission in here allows me to cp the file. I make a wild guess that 'w' in the 1st part is the one but it is supposed to be of the owner right? But I m not the owner of this file which is pretty obvious . But if that w specifies that I can copy the files then it very well means that i can even create the files provided we have a (rw) in the /etc/exports file.
