Hi,
Okay, read permission for everybody i.e. root, group and user but
excluding write and execute would be:
chmod 444 nybble.txt
To have read write and execute for root, read and execute for group and
read for all others:
chmod 754 nybble.txt
Just remember each bit in that order read, write and execute.
