I wrote these scripts and of course, I had to learn to
do some of the things in this work. Many of the ideas came from me
but the information came from various other linux users. Without their
massive contributions to the community, this project of mine would not
be possible. A list of acknowledgements below:

WELCOME AND RAMBLE WITH LICENSING
##########################################################################
Welcome to Raspbian-Toolbox. This is a useful little utility that
tries to setup, maintain, and keep up to date with the latest
software on your system. Raspbian-Toolbox is delivered as is and thus,
I can not be held accountable if something goes wrong. This software is
freely given under the GPL license and is distributable and changeable
as you see fit, I only ask that you give the author the credit for the
original work. Ubuntu-Toolbox has been tested and should work on your
device assuming that you are running a Raspberry Pi, or Raspbian-based system.
A cronjob is any task or script that you place in the crontab file to be
ran at a certain time.To not go to deep into it, the basic syntax is
this:
*     *     *   *    *        command to be executed
-     -     -   -    -
|     |     |   |    |
|     |     |   |    +----- day of week (0 - 6) (Sunday=0)
|     |     |   +------- month (1 - 12)
|     |     +--------- day of        month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59) source:
http://www.adminschoice.com/crontab-quick-reference
What I normally do is set the hosts updater to run at 8 every night ex.
00 20 * * * /bin/sh /home/USER/hostsupdater.sh.
I set it up under the root account by typing su followed by my password
in manjaro, sudo -i in Ubuntu systems and then typing crontab -e.
The maintenance scripts are ok to run manually each month.
It is recommended that you do not run these without being present.
Hoever, if you wish to run them as cron jobs then you can tweak the
cleaning routines as follows."sudo rm -r ./cache/*" should be changed to
"rm -r /home/USER/.cache/*" and etc. The setup script should only be
ran once to set the system up.

##########################################################################
INITIAL SET UP AND OTHER OPTIONS
##########################################################################
Initial setup with most installations of Raspbian/Raspberry Pi OS is 
automatically started on first boot, however, this is a modest array of 
settings shown to the user. For this reason, usually Raspi-config is 
installed as both a CLI and GUI. Noobs has this, however, they modify
the initial setup and add loads of extra software bloat to systems.
Flashing the software yourself gives you more control over what gets
installed on your flashy new mini-pc. In this script the user has access
to even more options that are not currently added to raspi-config or in 
the welcome screen. These settings have to do with ipv6 usage, memory tweaks,
firewall installation and enablement, etc. Most of these tweaks are safe
to implement, but some may not be needed as with regards to the memory side,
Raspberry Pi OS manages memory fairly competently on its own.

##########################################################################
OVER CLOCKING AND IMPROVING GPU PERFORMANCE
##########################################################################
Raspi-config also offers a couple of options with regards to managing 
overclocks for cpu chip and gpu memory allocation. Most online sources 
agree that gpu memory should be allocated to 128MB of memory for better
video performance. The command line version of the tool also offers
access to video driver options as well. The new video driver is meant to
help with certain conditions of screen tearing and hardware performance,
however, I have noticed that gpu acceleration on raspberry pi is sorely
lacking as of yet. The new video driver is helping, but even it is in its
infancy right now. Overclocking can also be administered in new Raspberry
Pi 4 systems through a file in the boot directory. This will allow the 
system to boot automatically with those settings. The file is called
config.txt and it has its own section for arm and gpu overclocking. 
Boards and chips will vary, but when setting these commands, it is 
imperative to not go too high at once and to offer adequate cooling
measures for your device. Canakit comes with heatsinks and a fan for 
just that. Furthermore, setting the board vertically with heatsinks 
can help with cooling as long as it has plenty of air on both sides.

##########################################################################
GPIO & FAN INSTALLATION ON PI 4
##########################################################################
If you get a pi from Canakit, it will come with a booklet and a diagram 
of GPIO map and where each circuit leads to on the board. The Fan takes 
up two such pins. If you're wiring up arduino it uses others. The pins 
are numbered on the graph and the graph will tell you what they do. I'll 
post a link to a picture of said diagram later. 

##########################################################################
MEMORY TWEAKS & SWAP MANIPULATION
##########################################################################
Memory is a crucial part of working with any computer device. Memory
stores important information for running programs and opening documents
in a temporary capacity for the processor to read and "process". Having 
enough RAM is vital to getting work done and keeping the system from 
crashing prematurely. Memory acts in a similar manner to Flash storage,
but it only holds information until either the program is no longer in use
or the system is shutdown or rebooted. Raspberry Pi devices are no different, 
having access to 2,4, and 8GB in the new Raspberry Pi 4, Raspberry Pi devices
are now doing more than ever before. Some of these devices can serve as a
desktop replacement. Memory has many facets to keeping the system afloat. 
Some Memory is used for cache purposes in case programs or files are needed
at a later time. Some is used for buffering or holding information in the 
case of moving large files around or downloading torrents. This Memory gets 
slowly cleared later when it is written to disk. The Kernel manages Memory on
Raspberry Pi's in a similar manner to other operating systems, though it appears
that it is more frequently cleared as Memory usually comes in such short supply 
on these devices and the platform is smaller. Everything is optimized for your
new single board computer. However, for some systems this can be tweaked even 
further. This won't work on every system, but those with more Memory might
see a slight benefit. Changing the swap value, dirty ratio, watermark scale
factor, etc. These all try to free as much RAM as possible as fast as possible
to ensure that it is available for later use. This helps in situations where
the device is powered on for longer periods of time like in servers. I have
added many of these tweaks to my script, but these can be commented out to 
ignore them during setup. The default swap size is often too small for these 
devices as well, manipulating that is a more advanced procedure which I will
cover later on.

##########################################################################
GETTING WIDEVINE ON CHROMIUM FOR DRM & DISABLING JAVASCRIPT
##########################################################################
Chromium can be custom built to come with widevine enabled from the start, 
however, it is not the case in Raspberry Pi OS as this would cause legal
disputes for the open-source software. There is a script made for this 
purpose and libwidevine is still available in the repositories. Perhaps 
I will implement a function for grabbing and running this script later.
By default, Chromium comes with Ublock Origin and H264 installed as 
extensions. Javascript is still fully enabled, but just like using 
adblockers can help with intense webpages, so too can disabling 
scripts and only allowing scripts the user trusts or wishes to run. 
Considered rather extreme by many, this concept is nigh essential to 
running bloated websites on a low end device, however, this can brick 
sites, so users can allow sites they deem trustworthy. There are Noscript 
like alternatives available, but nothing as good as using what's already 
in the browser.

ADBLOCKING THROUGH THE HOSTS FILE
##########################################################################
Setting up a custom hosts file can be selectively simple with the script
Hostsman4linux and the corresponding function HostsfileSelect Both have
the ability to compile and sort one central file out of multiple source
third party hosts files. These can be a great extra layer to your system
security regimen or can be a helpful adblocking tool allowing your
browser to be fast and clean from extensions. Running the main script
yourself is fine, but you have to run it as root. There is no other way
as of yet that I have found to give it proper clearance to manipulate
a secure system file like that without running sudo ./Hostsman4linux.sh.
I am thinking of making the Hostsman4linux script a bit more cron-
friendly in the future. Allowing users to use flags would give users the
ability to make this script run on a schedule and it would always give
them the desired hosts file. Alternatively, if you wish to run this
script from a menu as a regular user, chmoding the file to 755 might
help before storing it in the /usr/local/bin directory and creating a
desktop file for it. I will write a blog article for that later.
to find my blog just go to: https://techiegeek123.blogspot.com/ in a
browser. Update: I have finally created the perfect script for
automation. Now users are able to create the perfect hosts file
for them Without being bothered to answer questions. The defaults
I have chosen cover a broad spectrum of Ads, Trackers and Malware,
for your convenience.

RECOMMENDED SOFTWARE & PI IMAGER
##########################################################################
Recommended software is software chosen by the Raspbian Foundation to cover
the needs of everyone from children learning code, to advanced programmers
writing software for a living. Many pieces of this software come preloaded 
on Noobs loaded sd cards. Raspberry Pi OS, when loaded by you, comes with 
the bare minimum of software for moderate daily use. To do advanced 
coding one might desire the recommended packages which can be installed
later on by the user by opening a program titled "Recommended Software".
Aptly named, this software allows the user to easily check a box that will 
install the said pieces one by one or in a list. Pi imager is great software 
for loading Raspbian and formating said sd cards yourself, allowing you to 
build your own set up with a desktop or for a server in headless. rpi-imager 
allows you to choose which version of image you wish to install ranging from
Pure headless Raspbian to Full with other images including Librelec available.
To install this run apt install -y  rpi-imager or very soon this option will 
be available in my scripts.

##########################################################################
SD CARDS AND INSUFFICIENT POWER FOR PERFORMANCE
##########################################################################
Raspberry 3 and older versions use less power than raspberry pi 4.
Raspberry Pi uses a consistent stream of 5V power over a 2.5 to 3.5 Amp
power adapter. These adapters are crucial in getting the most out of the 
Pi. By default, the board itself uses around 800mAh to 1.2 Amps of power.
Adding usb drives increases this up to around 3 Amps depending on the
amount of drives plugged in, or the type of drives plugged in. This also
covers peripherals. This in turn also produces more heat which can impact
performance if the device is not properly cooled. SD cards rely on some 
of this juice to run. SD cards are much slower than USB on certain iop 
operations. While SD can read and write potentially faster at random, 
transfers and cached reads and writes can do a little better on USB, 
this is possibly why you may notice a slight lagginess on SD cards. 
Some SD cards are better for performance. Recommended SD cards by 
trusted carriers are important. Samsung and Sandisk are good brands 
to choose. SD card readers on Pi can be overclocked, but this is not 
recommended as it can have disasterous effects on the cards installed. 
SD cards also don't do as well after power interruptions. This might be 
something to avoid when running a Pi.

##########################################################################
SCREEN RESOLUTION
##########################################################################
As you can see with the newest releases of my toolbox scripts, I have
implemented a new function which leverages xrandr to allow the user to
pick and choose their screen resolution. Sometimes Linux does not always
choose the best resolution for your needs, this is why this was implemen-
ted. Simply type the number for ScreenFix and it will prompt you with
a list of possible screen resolutions supported by your distribution.
Choose the proper resolution to fit with your monitor and go. Sometimes
Linux uses ancient 800x600 resolutions or some other resolution that is
either too big or small and this can be caused by the driver or some other
issue. Xrandr will allow you to save your resolution in place and keep it
consistent between boots. Xrandr is installed in most distributions now-
adays. I have recently added a monitor configuration file to Github. Is a
template only and if you use it you will have to tweak it to fit your
needs. See 10-monitor.conf. 10-monitor.conf will go in
/etc/X11/xorg.conf.d/ On Raspbian systems, occassionally you will
notice black borders around the monitor. This is normal and can be fixed
by enabling overscanning. Overscanning is like Raspbian autocorrection. 
In the initial setup you might notice a box that is unchecked by default.
This enables overscanning.

##########################################################################
APT & DPKG
##########################################################################
Aptitude has been around in one form or another since Ubuntu and Ubuntu-
based systems began. Apt covers a wide range of applications, however,
the applications in Ubuntu repositories can sometimes be outdated or
scarce. Enter DPKG. DPKG handles files in a .deb format which can package
multiple files together in a tighter and smaller sized bundle. This bundle
can then be unarchived and assembled easily by a Debian-based system.
Ubuntu is built on Debian code, so this being carried over was only
natural. .deb packages still do not handle dependencies very well, This
is one of the reasons for some applications moving to Snap. Snap is yet
another package management system that is coming installed into newer
Ubuntu systems along with Flatpak. Between these two, the idea is that
dependency resolutions and more updated software would come faster and 
easier to the user and developers with just one package. It would be 
easier to maintain a Linux system or any other system if they were all 
using the same package across multiple platforms and distributions 
getting the same version updates at the same time. While a step in the 
right direction, it will be a while before they fully catch on.

##########################################################################
CLEANING AND MAINTENANCE
##########################################################################
Cleaning and maintaining Raspberry Pi OS is a good practice and is done 
in much the same way it is done on regular Ubuntu, but being Debian minor 
differences appear here and there, so I have added a function for 
expediting and automating much of this process at the behest of the user. 
I recommend running this once a month at least unless on critical servers. 
This will require a reboot to take full effect. This will also check 
disk and filesystem health on boot by running fsck. the desired method 
is using sudo shutdown -rF now, but the old-fashioned way still exists 
by creating a file called forcefsck in the root directory that will 
take precedence on next boot. I suggest doing this as often as needed. 

##########################################################################
RPI-UPDATE
##########################################################################
Rpi-update updates to the latest pre-release version of the kernel and 
headers as well as possible firmware. In most cases this might work ok,
but according to the Raspberry Pi Foundation, you shouldn't really need
to do this. Rpi-update is a script written by the foundation for those 
who like living on bleeding edge with their kernel modules and are
equipped to handle it when something breaks. As it stands, this is not
offered in this script, however, in the future I may add a separate function
for doing this if you so desire to do so.

##########################################################################
LOG FILES AND DISK WRITES
##########################################################################
Log files are a necessary part of troubleshooting for man techs, but
on some Pi's they are not really necessary as reloading is easier and 
faster now than it ever was before. Also, backup cards are cheaper than 
ever. There are suggestions to move the log directory to RAM, but this 
will blow up your RAM and not be freed until you reboot your system. 
Turning off the service, while this can free up resources, is just not 
a good idea either. While the log file can reduce the lifespan of the 
sd card, it's not as much of a problem as it used to be. With journald, 
you can tweak the amount of space taken up by the logs at any one given 
time. This helps the sd technology to automatically wear level more evenly. 
This in turn is the better option.

##########################################################################
TROUBLESHOOTING INFO
##########################################################################
This script has the ability to help with troubleshooting as well. It can
collect hardware and software information for troubleshooting issues
online as well as for reinstalling fresh in the future. This script
tries to make things as clear to read as possible by separating the
different information into categories. Each category pertains to things
such as hardware, software, login attempts and many more things. This
data will be saved to one rather large text file in the home folder of
the user who executes the script. Much of this will be useless to a new
user, so there are online forums for help.

##########################################################################
RPI-EEPROM BOOTLOADER CONFIGURATION
##########################################################################
The bootloader and chip firmware drivers are integral parts of the system.
They allow the Kernel and underlying software to talk to the board itself.
Updating Raspberry pi bootloaders and firmware drivers is a mixed bag on
dependability, however, many of the updates are very important for continued
smooth operation of the device. Installing these can help with compatibility
with newer wireless technologies, security and heat dissipation of the board, 
and even better support with newer kernels. Many of the firmware packages 
you might see are for Wireless, Audio, Bluetooth, etc, but RPI-EEPROM
is just as important. This package has to do with cooling and smooth 
operation of the board components and arm chip itself specifically. 
This is automatically updated now by default. In the early days it 
posed a risk, but now installing it is crucial and there are ways to
downgrade the configuration or roll it back to a previous date. EEPROM 
effects boot order and acts as kind of a grub and bios firmware all in one.

##########################################################################
DIFFERENCE BETWEEN ARM AND X86 PLATFORMS
##########################################################################
The difference between the two platforms comes down to their instruction
sets. Instructions are written in machine and allow the processor to 
handle a given task. ask the same task of both devices and the
ARM device will take longer to do the same work. Arms can do the same
work with half the chip size and or transistors. Desktops are clunky and
less efficient, however, they have the real estate to work faster. Arm 
devices are much like Mobile which includes our cell phones. They can do
amazing things with less power draw in a given amount of time as compared 
to their larger cousins. Much of the same software can be optimized to work
on either platform, however, the OS choices are limited on the ARM. On 
the face of it, it becomes a matter of software optimization. How small a
footprint can you create software to do the same job faster will determine 
time constraints for the smaller device.

##########################################################################
WHY IS MY NETWORK SEEMINGLY SLOWER? AND ONBOARD WIFI/BLUETOOTH
##########################################################################
Raspberry Pi 4 and Raspberry Pi 3 often get far different internet speeds
despite the 4 being slightly more powerful as a device. The reasons aren't
at all apparent for many people and some boards are still different than 
others. Best guess from looking at forums is that many Rasp-pi 4's suffer 
from insufficient clearance of the different receivers from LAN and WLAN 
and Bluetooth. As raspberry pi 4 is the first one to offer wifi and bluetooth
already built in, this seems like it makes sense. Add this to the fact that
Raspberry Pi's have to process all data they receive through their cpu, 
much the way a desktop would. Desktops do it faster, while Rpi's take
slightly longer. There are work arounds for this at the hardware level, 
by adding a wifi dongle you might get better speeds over wifi for example.
But I haven't tested this yet.

##########################################################################
LIMITED SOFTWARE AVAILABILITY? BLAME DEBIAN
##########################################################################
Debian seeks to favor stability over new and flashy. Debian holds Open
source values to their highest when developing and selecting software for 
a device running it. Debian and Raspbian are similar, however there are
differences in the platforms serviced. Raspbian comes with Chromium as 
a web browser(was epiphany), and Geany as a programming IDE. VLC is the 
media player by default(I would have chosen something lighter, but vlc -
has all the features). Mousepad is the text editor which is funny as 
Raspbian uses LXDE for the desktop and openbox for Window Manager. Both 
rely on using mostly free and open source or FOSS. Though it should be 
noted that Raspbian uses closed source code for the firmware.

##########################################################################
SUDO VERSION CHECKING
##########################################################################
With recent news of possible privilege escalation bugs found in sudo, I
figured it wise to include a sudo version check option in SystemInfo.
This will check for version numbers of sudo and sudo plugins. Versions
1.8 are privy to the bug and some early 1.9 versions(eg. 1.9.2). 1.9.5
should be immune, however as with sudo, many more bugs will eventually
be discovered. It is imperative to keep your system updated regularly
to patch these kinds of vulnerabilities.
