rebus - What famous line does this Linux command line represent?

The following shows a Linux command line with a # prompt:

#





                            echo -e 'AAAAHHH!!!\a' > /dev/null




#

It represents a famous line from a work of fiction. What line is that?

Answer

The answer is

"In space no one can hear you scream." The tagline for the Alien movie.

echo -e 'AAAAHHH!!!\a'

This is a scream. (Added bonus of \a telling the system to beep.)

> /dev/null

This redirects the output to the null device, effectively muting it.
