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.

tmpfs ~/.cache cleaner daemon-script idea, to clean RAM space while trying to minimize SSD writes

Tags hack, script, ssd, tmpfs

In line with the idea of reducing how much it's written on SSD, some people suggest using tmpfs for lots of things, one of them can be the ~/.cache directory. Which must be implemented in a per-user basis or with some pre-mount script that would do such tmpfs mounts before each user login. But regardless, the point is that they may spare the SSD, but not the RAM, obviously. If you quit a cache-heavy program, its cache would still be there, leaving other programs you're running with less RAM to use....

Bash script that pops-up notification with a bar graph of where you're spending your time on PC

Preliminary but works, even though I'm probably doing some stuff wrong/dumbly. Basically, "if input is idle for less than two minutes, then grep the active window, if it's the same active window for two times in three 30-second time-windows, count it as active ; after looping N times, show a rudimentary bar graph of how many times each logged window was used."

It would be nicer to actually transform the counting of each program in a percentage of the total, but it's good...

New file name generator script/function, to avoid overwrites w/o user input

Posted 03-27-2016 at 07:11 PM by the dsc (linux-related notes)

Usage examples:

cp/mv/ln/etc file11.txt $(newname "/some/path/file11.txt")

cp/mv/ln/etc file11.txt $(newname "/some/path/whatever.txt")


If there's a file11.txt or whatever.txt already there, it will rename automatically to file11(1).txt or whatever(1).txt, and (N+1) from then on.

The whole path/name must be between quotes because of spaces and such things.

May be dangerous and somehow make you lose files...

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...

Pseudo-template noob hack that may apply for several situations

Posted 04-12-2012 at 04:10 PM by the dsc (linux-related notes)
Updated 04-12-2012 at 04:14 PM by the dsc

There's a painting software, "mypaint", which is very nice, but it does not support templates, at least not yet.

I've created a template (just a "blank" file with the correct resolution and whatnot) on GIMP, saved it as "ora", but instead of opening this file manually every time, and remembering to save it with a new name in order to not overwrite the template, I came up with a script that will create a new name automatically, with no risk of overwriting...
