- .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.
