Blocklist-Update.sh

Blocklist-Update.sh is a script that I wrote to manage blocklists from bluetack etc to be used in conjunction with Transmission torrent downloader in Linux/MacOS. The script can be taylored to work with Qbittorrent as well, but the placement of the blocklists means you'd have to redirect the blocklist to go somewhere locally manageable as Transmission uses its own blocklist directory in .config. I believe there are about 10 lists there now. It works well for my needs. It can be ran weekly using crontab in standard user profile.  To download:  blocklist-update.sh To download the others:  Github

WRITING SUCCESSFUL BASH SCRIPTS TUTORIAL #1 :INTRO

When performing command line tasks or (CLI) jobs in Linux, it can become tedious when there is a lot to do, for instance, working as an administrator for a small/medium/large company. Automation is very helpful when parsing large files or running multiple commands at once more than one time a day. Scripts are basically text documents that run a series of commands in succession of one another. Think of it as writing for a play. Scripts use the #! sign at the top, this is known as a shabang. The shabang alerts Bash that the following text document is a script and should be ran as a succession of lines as such. The environment comes after the shabang like so: #!/bin/env/ replacing env with the environment the script is to be read from. Most Bash ran scripts have the environment of shell. Python and Ruby use their own environments respectively.

Bash and Shell are not the same things. Bash or Bourne Again Shell handles lots of commands very differently to regular shell. Shell doesn’t do well with complex tasks so for this reason, most complex scripts are written with #!/bin/bash. There are plenty of ways to do different tasks within bash, some commands are more complex for a more complex need, however, other complex code is used to show off a coder’s skills. Writing code in any sense tells a bit about the one writing it. Their thought processes and so on. When a developer of an os sets certain scripts to be ran from the system’s back end, many of these scripts use Anacron as a scheduler and they use #!/bin/sh as the environment. These scripts are usually found in the /etc /cron.daily monthly or weekly folders. These scripts usually consist of one or two lines to do tasks like updating the local database and updating man databases or rotating logs around.

Bash is good for most needs, however, it is imperative to plan out your next script with the job in mind. What am I trying to accomplish? Will this deal with numbers or strings? How will this work automated? In the next few tutorials I will go over some basic syntax for everyday commands. I will even talk more about Systemd timers and scheduling.


Some examples can be found here.

NOSCRIPT CONFIGURATION FOR PALE MOON SPECIFICALLY

I wrote an article before about making Pale Moon more private. I covered a few of the settings and back end changes I make each time I install it. I mentioned Noscript, but I didn’t give any details about how I set it up. First though, you have to get the version already marked for your version of “Firefox” or in this case, Pale Moon. If you went to https://addons.palemoon.org/addon/noscript/ you would probably find the Pale Moon addons page devoted to the newest possible Noscript being marked specifically for Pale Moon. Other versions may work, but these are hybrid addons and the closer we get to Noscript 10, the less I trust it to work with Pale Moon specifically. I just opt to stick with 5.0.6. There have been people asking about what happens when Maone, the developer stops supporting the hybrid versions of Noscript, “Will it work with Pale Moon?” Why yes it will. Noscript blocks scripts, that’s its main function and it will do that as long as Java script exists on a page. ...

SSD PARTITION ALIGNMENT

I was searching for more information regarding SSDs last night as that is what I now use, I found an interesting little tip that most users will never have to worry about, but people using Arch Linux, Manjaro or Windows that was cloned from another drive may want to consider checking this. The Partition manager within Linux normally takes good care to ensure that you have some free space to be used by the SSD in the event that a cell becomes worn out or corrupted. Also, Linux generally ensures that a proper amount of unallocated drive space is set aside preceeding the partition. However, on my own image of Manjaro, I discovered that this was not the case. The partition was “out of alignment”. To fix this situation, I found an article on  Lifehacker that went into instructional detail about how to solve this from a live environment or an image of Gparted . Gparted is a separate live environment of Linux that is based on Debian and uses Gparted as the main tool to manage...

PALE MOON PRIVACY SETUP

I did a review of Pale Moon back when 27.6.2 came out in linux. I had mostly great things to say about the browser then and my feelings towards it have not changed. Pale Moon is a very useful tool for scowering the net. It has privacy at its core with a few implementations made by Moonchild, the lead developer, built in. I also mentioned the point that Pale Moon has a canvas poisoning feature in the backend, however, I wasn’t very clear about how to turn it on. I thought in this tutorial, I’d show with a series of screen shots, some of the useful settings and preferences that I change to make Pale Moon a bit more private. I also thought I’d take this time to rant a little more about some of the not so savory issues with Firefox which have recently come under scrutiny by various people in the the Linux world. First order of business, if you haven’t heard, Mozilla recently added an extension into their browser which gave people ads. That’s right, they were ads for a specific t...
