When I use the
type command to find out if
cat is a shell built-in or an external program I get the output below:
-$ type cat cat is hashed (/bin/cat) -$
Does this mean that
cat is an external program which is
I got confused, because when I checked the output below for
echo I got to see that it is a
built-in but also a program
-$ type echo echo is a shell builtin -$ which echo /bin/echo -$
So I could not use the logic that
/bin/cat necessarily means an external program, because echo was
/bin/echo but still a built-in.
So how do I know what
cat is? Built-in or external?
