SCREENDUMP(1)                          General Commands Manual                         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 screen‐‐
       dump as root.
