How do I look at the last few lines of an output log on Windows?

On Unix/OSXOS X, the utility is called "tail." However, you will have to find a replacement. Look here for Unix tools for Windows: http://unxutils.sourceforge.net/

As of Qube 6.5, there is a utility in $QBDIR/utils called qbtail.py. This works just as the tail command would on unixUnix/osxOS X, but it does require that Python is installed.
