the wall command

[trashthing]

hi. this is dumb, but, can someone tell me how to use the command, wall? everytime i try to run the command:

wall (filename)

it says:

wall: will not read (filename) - use stdin.

i don't get what to do.

[serz]

To output the content of a file with wall do: wall < file
