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.

KDE's "ark" as a command-line universal (un)archiver

Posted 07-28-2014 at 02:44 PM by the dsc (linux-related notes)
Tags ark, zip

For some reason I was having issues with some zip files. "Unzip" wouldn't unzip them, but ark (and perhaps other GUI archivers) would.

Fortunately ark can be used as a command line tool as well, which can be better than needlessly opening the full GUI just to make something so trivial. You still can invoke just the dialog, anyway.

But in order to extract something, for example, one can just use:

ark -b file.zip -o ./extantfolder

A clock as the header of Openbox' root menu

Posted 07-15-2014 at 04:15 PM by the dsc (linux-related notes)
Updated 07-16-2014 at 06:35 PM by the dsc (grammar?)

If you want a clock instead of the typical "openbox"-labeled separator at the top of the root menu. The way to do that isn't the most nice and convenient way imaginable, though. Essentially you have the root menu as a pipe menu.


The executed script is just a sed one liner:

Code:
 sed "s|INSERT-CLOCK-HERE|$(date +'%-H:%M')|" $HOME/.config/openbox/menu-sed.xml
This a "24 hour" clock format, without leading zeros,...

To move files "copied" on clipboard (Konqueror/perhaps dolphin) to the place you're on a terminal, without navigating/browsing the folders on the file manager, one can use:

xsel -b | while read f ; do mv -i "${f#*file://}" ./ ; done

As "copied" files on Konqueror are registered on the clipboard as a list with "file://" preceding the path. Perhaps could be aliased...

Interesting "ask ubuntu" message related to swappiness tweaks

Posted 07-09-2014 at 09:06 PM by the dsc (linux-related notes)

Quote:

Why most people recommend to reduce swappiness to 10-20?
Because most believe that swapping = bad and that if you don't reduce swappiness, the system will swap when it really doesn't need to. Neither of those are really true. People associate swapping with times where their system is getting bogged down - however, it's mostly swapping because the system

[rant] Linux seriously needs some efforts in theming standards/unification

KDE, QT, GTK, TK, all in several versions and with changing variables and whatnot at every version, and even within a single version.

One would think that QT and KDE are more or less the same, but turns out that, at least from outside KDE, one can't fully define the theme settings (or UI font specifically) from KDE's "appearance" settings. Even for apps that aren't "standalone QT", but KDE! Like fonts on konqueror, and probably dolphin too. KDE has a longstanding...
