Great rundown of getopt and getopts
http://aplawrence.com/Unix/getopts.html
Examples of getopts usage:

And a really good example script using bash getopt long options:

Edit:
That was all fine and dandy until my network shares stared dropping and failing to mount with message:
mount error(12): Cannot allocate memory
Yup, its a Windows problem. Tell windows to allocate more resouces for file sharing: http://alan.lamielle.net/2009/09/03/windows-7-nonpaged-pool-srv-error-2017

rm "$1".wav I received Googled by Ken Auletta for Christmas and don't feel like bringing all 12 discs back to college with me. Luckily, ripping each disc as a single audio file couldn't be easier in linux, the trick is abcde, a great program that acts as puppetmaster for a bunch of other programs (cdparanoia, cdda2wav, dagrab, flac, lame, faac, id3v2, etc, etc). In otherwords, it does all the work and keeps life simple
abcde -1 -N -o mp3:"-b 128"
-1 Rip the disc to a single file
-N "Non-interactive" aka "piss-off mode." Don't bother me with questions, the CDDB info you find is just fine
-o mp3:"-b 128" Output an mp3 file and tell lame that I want 128 kbps
sudo aptitude install id3v2 lame abcde
Writing backup scripts for UVC.
Using a lot of Bash scripting resources. The Gentoo community has created an excellent set of scripting cheat sheets:lower1=`echo $1 | tr '[:upper:]' '[:lower:]'`Okay, looked a little more, looks like Bash v4 can do case change parameter expansions, but I'm at version 3.1.17, so I'll have to wait :PDirectory Size
du -hs
grep -v ...I'm also using the -i flag (ignore case) even though the cases all came from the same host on linux and should match. Note: df is used to find free space instead of space consumed.A Good Find
find . -type d</br>find . -type f
IFS=$newline tar some stuff # separate w/ newlines unset IFSThese pages are good resources:
