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.

Rough script that waits until processes finish their businesses, then exit

Posted 06-15-2015 at 04:17 PM by the dsc (linux-related notes)

The processes are given as a single variable, thus one must use quotes if there's more than one process to wait for.

Usage example:

./waitprocs "lame avconv sox tar" && self-destruct

My previous attempt with a "counting" system didn't work, so I've tried a different approach. For any given process, it will check if it's running, if it is, it creates a temporary file with its name on a temporary work folder; if it isn't, it...

Make a bash script recognize bash aliases

Posted 05-12-2015 at 04:16 PM by the dsc (linux-related notes)
Updated 05-12-2015 at 04:22 PM by the dsc (mismatched tags)

Say, if you have a script that would take as a parameter something that you have aliased, it wouldn't work.

I mean:

$ ./script.sh myalias whatever else
/home/dude/scripts/script.sh: line 3: myalias: command not found



In order to make it work, the said script must include:

Code:
shopt -s expand_aliases
source ~/.bash_aliases
(Or wherever your aliases are set, which would preferably be...

Idea for a script to prevent xscreensaver while watching videos on a browser

Posted 03-15-2015 at 12:54 AM by the dsc (linux-related notes)
Updated 06-25-2015 at 12:04 PM by the dsc (grammar)

The core concept is just:


Code:
while true ; do

wmctrl -l | grep -i "youtube\|vimeo" && xscreensaver-command -deactivate

sleep 5m

done
Perhaps it would be more elegant to have something that somehow works more accordingly to xscreensaver's time rather than this thing that has smaller cycles just to play it safe.

Won't work for embedded videos, though, as "youtube"...

Mozilla seems to work okay with Chrome's flash player

Posted 02-21-2015 at 10:16 PM by the dsc (linux-related notes)
Updated 02-23-2015 at 04:44 AM by the dsc

I'm not really a fan of flash, but since I'm trying to switch from Chrome to Iceweasel, which seems to be less sluggish in my machine, and I don't like the idea of using a plugin from the late 90s when I have to, I decided to try the wrap-around trick/plugin I've found. It seems to be working normally, as fas as I can tell.

It had a few more dependencies than stated in the how-to, but the make/configure output...
