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.

Semi-auto-generated, nicely formatted, apropos-like list of your custom bash functions

Posted 10-01-2015 at 12:35 AM by the dsc (linux-related notes)

Code:

bold=$(tput bold)
normal=$(tput sgr0)

lsfunctions ()
{
tail -n+10 /path/to/custom-bash-functions | grep "()" | sort | sed 's|(.*#||'  | sed "s|^|${bold}|;s|\ |${normal}\ |"
}

↑ Change the number "10" to whichever line you want to start grepping the functions

"lsfunctions" would be like "apropos /usr/bin/*", or whatever really works, but restricted to your custom...

☻☻☻ Pipeing youtube-dl output to a given player (and having it as a mini-script)

Code:

youtube-dl -f ${2:-5} $1 -q -o - | mpv -

The first parameter is the youtube url, for a single video, and the second, optional, the quality code, like "best", "worst", or a given number. The default there (5) is the 240p flv.

Just "mpv youtube-URL" was supposed to work, but isn't working right now for me. It says the youtube-dl version is old,...

KDE hidden command line tools

Posted 09-17-2015 at 02:03 PM by the dsc (linux-related notes)
Updated 09-24-2015 at 08:02 PM by the dsc

Haven't checked yet, posting as a "shared bookmark" and to myself:

http://www.bramschoenmakers.nl/node/610.html

I'm particularly interested in "kde-move". I've actually came up with bash-script approximations to the functionality of auto-renaming the moved files when the target directory has files with the same file names, but I've only made something that just does that by default, whereas KDE can do that but also allows one to compare and rename,...

Adding a "copy image to clipboard" editor (not really) to geeqie

Posted 09-07-2015 at 01:22 AM by the dsc (linux-related notes)
Updated 11-17-2016 at 03:46 PM by the dsc (UPDATE!)

Edit: I've just found a method that seems much simpler and more lightweight

The copy to clipboard editor can be just xclip! (Therefore one of my first statements in the first version of this post is probably false, and possibly was wrong even then).

Code:

xclip -selection c -t image/jpg < "%f"

It doesn't matter that the source isn't a jpeg, you can even replace it for png, it's probably an on-the-fly reencoding or something, I'm not sure.

[solved?] New GTK2 bug? Maybe it's a QtCurve bug. Theme changes randomly

Posted 08-30-2015 at 03:23 PM by the dsc (linux-related notes)
Updated 11-21-2015 at 06:22 PM by the dsc

Tags bugs, theme

UPDATE: whatever happened before, it seems that now it can be partly solved by simply commenting out the font-related lines in /usr/share/themes/QtCurve/gtk-2.0/kdeglobals (not to be confused with KDE's own file with the same name!).

After a while (after a massive upgrade) the randomness of the thing stopped, the correct theming consistently fails. More evidently fonts, icon theme, and colors (including tooltips' colors). I'm not sure the widget's "design" is also affected,...
