Setting File Permissions
December 20, 1999
The table below displays the various file permissions. Permissions
are set for owner, group and everyone else respectively. That means
the first number in the set of 3 represents the owner, the second
represents the group and the last represents everyone else. Therefore,
if you need to change file permissions to say
Read, Write, Execute for owner and Read,
Execute for the group and everyone else you would
chmod 755 file-name.

All this is well and good, but what does it mean to you? Exactly
