The figures are calculated in the following way for the owner 400 has read rights 200 has write rights 100 has execute rights for the group 40 has read rights 20 has write rights 10 has execute rights for everyone else 4 has read rights 2 has write rights 1 has execute rights so lets say chavez wants his file gold to hav read and write rights for the owner and only read rights for the group and also only read rights for everyone else he would set his permissions in the following way: 400 + 200 = 600 40 = 40 4 = 4 so you add them up it comes to 644 so then he would run chmod 0644 gold If you want the program to run suid i.e runs under the id of the person who owns it then the mode is 4000 if you want it to run sgid i.e under the group id of its group owner you then add 2000 so lets say the above file is to be suid then he would have run chmod 4644 gold However do not use suid and sgid programs they can be a really big security hole especially if they are owned by root.
