When working on a complex command line, it's best to use editor. This can be done very simply in bash (AFAIK, might work on other shells as well), simply by defining the EDITOR environment variable and typing C-x C-e (i.e., Control-X Control-E). Afterwards, your editor will appear and you can edit the command line, save the file, and exit the editor. Done!

If you're using multiple sound sources, for example, Youtube, Skype, and MPlayer, all at the same time, you are going to run into problems with MPlayer because, by default, MPlayer tries to use OSS. With OSS, having multiple sound sources playing simultaneously is not possible because they lock the special file /dev/dsp. On the other hand, instructing MPlayer to use ALSA on every command line is cumbersome. Instead, edit MPlayer's configuration file ~/.mplayer/config and add the following property

ao=alsa

You can use find with multiple expressions by combining them in logical expressions. For example, to find both JavaScript and HTML files in a given folder:

$ find . \( -iname "*.js" -o -iname "*.html" \)

The flag -o is the OR operator. There is also not (!), and (-a), and comma (,). The parenthesis escapes are necessary for the shell.
