Linux 2.6 - man page for screendump (linux section 1)

SCREENDUMP(1)				  Linux Console 			    SCREENDUMP(1)

NAME
       screendump - dump the contents of a virtual console to stdout

SYNOPSIS
       screendump [ N ]

DESCRIPTION
       The  screendump	command dumps the contents of virtual console N , (or the current console
       if N is omitted) to standard out.

       Just saying
	      cat /dev/vcsN
       has a similar effect.

NOTES
       For security reasons, screendump uses linux devices "virtual console screen" and  "virtual
       console screen with attributes" to give access for screendump.

       Ensure these files exist, using

	      cd /dev for i in 0 1 2 3 ...; do
		   mknod vcs$i c 7 $i
		   mknod vcsa$i c 7 `expr 128 + $i`
	      done

       (filling  in  the  ellipses)  and  give	the  device files appropriate permissions, or run
       screendump as root.
