File permission information
Plz guide me about the following information .
drwxr-xr-x 3 jack smith 180 Feb 20 17:23 jack.txt
what 3 means here
and what is 180 ?
It is confusing jack & the word smith.
Last guide me any site where i can collect further information about file permissions i.e to add or remove permission
Thanks again for your kind co-operation
