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

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...

Example script to run and manage a service (tcpdump) with managed logging.

Posted 10-11-2012 at 07:59 PM by konsolebox
Updated 05-27-2018 at 03:10 PM by konsolebox

I made this script as a reply to a question on a thread before. The accidentally simplified complexity of it amazes me so I thought that it would be nice to post this on a blog as well. Original thread: https://www.linuxquestions.org/quest...cpdump-800385/

The script runs and manages a service (tcpdump). It could also automatically delete files older than C days, and reduce the size of a logfile if it's already larger than N bytes....
