For the future, you may want to take a look at gnu/screen.
When you are running your terminal sessions under gnu/screen and you
suddenly realize that you need to take a screen dump on the fly, all you
need to do is:
· issue the gnu/screen escape keyboard action (Ctrl-A by default)
· :hardcopy -h dumpfile
The -h flag causes gnu/screen to write the contents of the current
display as well as the contents of the scrollback buffer to the
specified file.
The point is that it's always there ready for you to use .. you don't
need to do anything special prior to starting your debugging session &
whatnot.
Needless to say that there a tons of other great features in gnu/screen
such as advanced copying & pasting between terminal sessions and
activating/deactivating session logging on the fly .. among many others.
For a terse introduction to gnu/screen's capabilities you could read
the following article :
http://jmcpherson.org/screen.html
For an in-depth description of gnu/screen's many talents I'm afraid that
there is no advanced tutorial that I am aware of and you will have to
study the excellent but somewhat unfriendly manual (man screen).
