.TH SCREENDUMP 8
|
||
|
|
.SH NAME
|
||
|
|
screendump \- write current console screen to standard output
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B screendump
|
||
|
|
.SH DESCRIPTION
|
||
|
|
.B 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 each line.
|
||
|
|
.SH NOTES
|
||
|
|
The most common use of
|
||
|
|
.BR 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.
|
||
|
|
.PP
|
||
|
|
This version is for IBM-PC architecture only.
|
||
|
|
.SH BUGS
|
||
|
|
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
|
||
|
|
.BR screendump
|
||
|
|
to send notes to someone about problems that occur while using
|
||
|
|
.BR MINIX
|
||
|
|
you must remember to toggle to software scrolling before you make the dump.
|
||
|
|
It will also be necessary to use
|
||
|
|
.BR su ,
|
||
|
|
because
|
||
|
|
.BR /dev/mem
|
||
|
|
is normally not world readable.
