I am trying to delimit the number of programs that have SUID permission. Following a friendly recommendation, I found the programs that have SUID by:
find / -type f -perm -u+s -or -perm -g+s I attempted to change SUID on some of the results, again following a suggestion: chmod -s file However, this command works sometimes, and sometimes only results in a "permission denied, operation not permitted" message. For instance, /usr/bin/cu and /usr/bin/rsh resulted in that error message, but /usr/bin/lpr did work. Why the difference? Thank you, Eric
