strip is a GNU binary utility that is used to remove information in a compiled binary or object file that is not needed for its execution.This information typically includes debugging information and symbol tables; however, the exact scope of the changes made to the binary is left to the discretion of the program's implementer by using the command-line options.
rm (short for remove) is a basic command on Unix and Unix-like operating systems used to remove objects such as computer files, directories and symbolic links from file systems and also special files such as device nodes, pipes and sockets, similar to the del command in MS-DOS, OS/2, and Microsoft Windows.

File deletion is the removal of a file from a computer's file system. All operating systems include commands for deleting files ( rm on Unix and Linux , [ 1 ] era in CP/M and DR-DOS , del / erase in MS-DOS / PC DOS , DR-DOS, Microsoft Windows etc.).
shred is a command on Unix-like operating systems that can be used to securely delete files and devices so that it is extremely difficult to recover them, even with specialized hardware and technology; assuming recovery is possible at all, which is not always the case.
It includes all commands that are standardized by the Internet Engineering Task Force (IETF) in RFC 959, plus extensions. Note that most command-line FTP clients present their own non-standard set of commands to users. For example, GET is the common user command to download a file instead of the raw command RETR.
The wheel group is a special user group used on some Unix systems, mostly BSD systems, [citation needed] to control access to the su [4] [5] or sudo command, which allows a user to masquerade as another user (usually the super user). [1] [2] [6] Debian and its derivatives create a group called sudo with purpose similar to that of a wheel group. [7]
