Which of the following find commands will print out a list of files owned by root and with the SUID bit set in /usr?
find /usr -uid 0 -perm +4000
find -user root +mode +s /usr
find -type suid -username root -d /usr
find /usr -ls *s* -u root
find /usr -suid -perm +4000
Referência recomendada para estudo
find /usr -uid 0 -perm +4000 is the correct command: -uid 0 filters by user root, and -perm +4000 (or /4000) filters by the SUID bit.
-uid 0
-perm +4000
/4000
