Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Apparent bug with KDE/plasma file associations

At least in Ubuntu wily, it doesn't seem to allow you to chose the default application to open a file type. You try to do it, but it "magically" restores the previous default association before your eyes. Even if you chanced the config file, somehow. (I'm assuming it's mimeapps.lst, but I'm not sure. It seems that it's cool nowadays to have cryptic, hidden config files, avoiding to mention them unless strictly necessary, pretending it's all magic and config files don't exist)

Silly volume control scripts for openbox that probably won't work for everyone

# volume changer+notifier, using notify-send, and tested only with xfce4-notifyd
# the syntax is the same of the "end" of what you'd use in plain amixer, see "$1"
# Ex.: 5%-, 5%+, 30, 60%

com=(`amixer set "Master" $1`)


# and here's why it won't work for everybody. The output of amixer includes
# things like soundcard features, which are array elements I'm just

kwrite "vi input mode" enabled accidentaly is quite annoying

First of all, you may be used to sometimes pasting stuff with shift+control+V instead of just control+V. Perhaps that's the way it's done in nano and/or some terminal emulators. The problem is that it's now also the default shortcut to enable "vi edit mode" in kwrite.

For people who like myself, don't really get "vi", using nano or something like that when forced to use cli editors, if you're in kwrite (perhaps also kate) and all of a sudden it seems to behave...

Parsing script arguments in bash, without getopt(s)

Tags arguments, bash

Nifty. Just found that on stackoverflow:

I originally answered the question as the OP asked. This Q/A is getting a lot of attention, so I should also offer the non-magic way to do this. I'm going to expand upon guneysus's answer to fix the nasty sed and include Tobias Kienzler's suggestion.
