Solution
On Ubuntu 14.04 LTS, "write" is a system call and an executable.
Here's why:
-
System Call: In the context of an operating system like Ubuntu, a system call is a programmatic way in which a computer program requests a service from the kernel of the operating system. "write" is a system call that writes to a file descriptor.
-
Executable: In Ubuntu, "write" is also a command-line utility that allows you to send messages to another user logged into the same system, by writing to a specific terminal device. This utility is an executable file.
It's not a kernel routine, library call, or a game.
