all answers given are wrong. Tested on ubuntu. ~$ find /usr -uid 0 -perm +4000 find: invalid mode ‘+4000’ ~$ find -user root +mode +s /usr find: paths must precede expression: `+mode' ~$ find -type suid -username root -d /usr find: Must separate multiple arguments to -type using: ',' ~$ find /usr -ls \*s\* -u root find: paths must precede expression: `*s*' ~$ find /usr -suid -perm +4000 find: unknown predicate `-suid'
