debian /var/lock permissions

[jwantz at hpcc2.hpcc.noaa.gov]

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.

> Hi Jim. I think I get it now, but what are the bit numbers for read and right? So based on the fact that I know execute is 7, chmod 777 myfile.txt would give root, user, and world read right and execute permissions on myfile.txt?
