find [path_to_search] -perm /u=s
But in above syntax we could face some error. So in order to handle these errors, we will redirect them to file /dev/null which is also known as a null device. Null device is a file in linux that discards all the data written to it without throwing any error and shows that write operation succeeded. Below example reflects the whole scenario.
find / -perm /u=s 2>/dev/null
/ –> path to root directory
-perm –> permission
/u=s –> Here u is for owner of the file, s stands for suid bit
2> –> ‘2’ is file descriptor for stderr and redirects ‘>’ them to null device file
/dev/null –> Null device file
