There is no "command not found" error that can be returned from execvp. The closest is ENOENT, which means that the file specified (or its interpreter, or a required dynamic library) was not found.

If you want, your program could print out "command not found" rather than the text returned by strerror.

Because "command not found" does not correspond to a standard error code (see e.g. http://linux.die.net/man/3/errno).
