Which of the following find commands will print out a list of files owned by root and with the SUID bit set in /usr?

Afind /usr -uid 0 -perm +4000

Bfind -user root +mode +s /usr

Cfind -type suid -username root -d /usr

Dfind /usr -ls \*s\* -u root

Efind /usr -suid -perm +4000

Show Suggested Answer

Suggested Answer: A

This command will find all the files in the /usr directory that have the user ID (UID) of 0, which is the root user, and have the permission of 4000, which is the SUID bit. The SUID bit allows the file to be executed with the privileges of the file owner, regardless of who runs it. The -uid option tests for a specific UID, and the -perm option tests for a specific permission. The + sign before the permission means that at least those bits are set; the - sign means that exactly those bits are set. The other options are either invalid or do not match the criteria.Reference:
