setuid - Wikipedia, the free encyclopedia

setuid - Wikipedia, the free encyclopedia: "The setuid and setgid bits are normally set with the command chmod by setting the high-order octal digit to 4 (for setuid) or 2 (for setgid). "chmod 6711 file" will set both the setuid and setgid bits (2+4=6), make the file read/write/executable for the owner (7), and executable by the group (first 1) and others (second 1). When a user other than the owner executes the file, the process will run with user and group permissions set upon it by its owner. For example, if the file is owned by user root and group wheel, it will run as root:wheel no matter who executes the file."
