There is also an option running in screen session logging the output.
Code:
screen -L -Logfile $HOME/mysession.log -S yumscreen
# do your update
exit
Look for the file $HOME/mysession.log or log/path you require.
You will also benefit in screen if your network connection breaks or similar issues .. turn off putty by accident
The process will continue to run and can be attached again.
It is a great tool and comes on most operating systems.

CEREAL(1) User Commands CEREAL(1)NAME
cereal - client program to attach to cereal session
SYNOPSIS
cereal command [args]
DESCRIPTION
cereal is the client program to attach to a running cereal session.
SUBCOMMANDS
cereal takes various subcommands:
attach SESSION
Attach to (take control of) cereal session SESSION. This puts the user into a cereal console, provided by a command-restricted
screen session. To detach from an attached session, use "C- d". For help on other available commands, use "C- ?". Cereal uses a
limited instance of screen to provide the console. See screen(1) for more info on the available commands. `a' may be used in place
of `attach'.
follow [options] SESSION
Follow (watch, without being able to intervene) a cereal session SESSION. The options are: -c [--cat] to cat log instead of follow;
-p [--path] to output just the path to the log file and exit. `f' may be used in place of `follow'.
list [SESSION]...
List session(s). With no arguments, will list all sessions. The leading three characters in the list indicate: whether the session
is running (+) or not (-) or in some unknown state (?), whether the user can attach to the session (a) or not (-), whether the user
can follow the session (f) or not (-). If the session state is unknown (?), it's usually because the user asking for information
about the session can't read the session stat file. `l' may be used in place of `list'.
help Output a brief usage summary. `h' or `?' may be used in place of `help'.
EXIT STATUS
Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.
AUTHOR
Written by Jameson Rollins and Daniel Kahn Gillmor.
BUGS
If the invoking user does not have read and execute access to the cereal session's supervise directory, `cereal list' may not always indi-
cate that session's status accurately.
REPORTING BUGS
Report bugs to <cereal@fifthhorseman.net>.
