linux: my usual ~/.bashrc file

This is the typical ~/.bashrc file I use, especially on cygwin/mintty on Windows boxes. It's work-in-progress and keeps evolving.

Note the handy little shell function, tailHelpAlert, that was designed to run on cygwin, on the Windows box where HelpAlert is running. It determines which is the correct (i.e. most recent) HelpAlert log, and then tails it. You don't have to know which build of HelpAlert you're running, or which temp directory the logs are going to right now.

Another handy little utility is the diskhoggers alias which is a cute little bit of nixcraft (works only on RPM-based distros, of course) to determine which packages (i.e. RPMs) are hogging the most disk space. Very handy when you're critically short of HDD real estate and want to remove junk and clutter quickly.
