Whenever you’re working with the file directory structure or with text in general, you can’t do any better than using the command line.  For example, I was recently copying a bunch of files off of some old CDs because I was noticing that they were starting to develop bit-rot.  (I couldn’t access all the files anymore)  For reasons I don’t wish to get into right now, it’s easier to not have spaces in filenames in Linux.  It’s not because Linux can’t handle spaces in filenames - it can.  But if you’re a semi-hacker like me, spaces in filenames can wreak total havoc on your scripts.  So I wanted to remove spaces off of around 200 or so files.
