A Brief Overview on File Permissions

A Brief Overview on File Permissions

0400 read by user
0200 write by user
0100 execute by user

0040 read by group
0020 write by group
0010 execute by group

0004 read by world
0002 write by world
0001 execute by world

By adding the permissions together, you will come up with the number that corresponds to the permission. For example, 400+200+100+40+20+10+4+2+1=777 - read/write/execute by user/group/world.

Thanks,
