say
A human may "say" things to a computer by typing them on a
terminal. "To list a directory verbosely, say "ls -l"."
Tends to imply a {newline}-terminated command (a "sentence").
A computer may "say" things to you, even if it doesn't have a
speech synthesiser, by displaying them on a terminal in
response to your commands. This usage often confuses
{mundane}s.
