## 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 **screen**‐‐
       **dump** as root.
