screendump - write current console screen to standard output
Screendump prints the contents of the console screen to standard output.
It does this by reading the screen memory, skipping over attribute bytes,
omitting trailing blanks and inserting a newline character at the end of
The most common use of screendump is with output redirected to a file.
This allows screen displays (including output of F-keys) to be captured
for inclusion in other documents.
This version is for IBM-PC architecture only.
A network user captures an image of the main console, not his or her own
screen. The output will usually not be what you expect if the display is
in hardware scrolling mode, since in that mode the order of the lines in
screen memory may not be the same as what appears on the screen. If you
expect to use screendump to send notes to someone about problems that
occur while using MINIX you must remember to toggle to software scrolling
before you make the dump. It will also be necessary to use su, because
/dev/mem is normally not world readable.
