Create required directories

Use the following commands to create the required directories. The directoires will hold doumentation for applications, lists to indicate which applications to install/remove and for the script itself.

Commands
The following commands can be used

Create required files

Use the following commands to create the required files. These files will include the script itself and be used by the script to get the names of the packages to be installed/removed

Commands
The following commands can be used

Get path to backup drive

The first thing the script will need to do is to get the path to the drive containing the files that will be copied to the new home directory. This can be done with a user input asking to provide the path. This path will then be stored in a variable called BACKUP.

Commands
The following commands can be used

Backup important system files

The following files are often changed or modified and should be backed up before doing so. It is typically good practice to do this, soon after the operating system has been installed.

Commands
The following commands can be used to back up these files. A file will be created with a .bak extension in the same directory containing the file. If these files are misconfigured in the future... they can easily be recoved by deleting the misconfigured copy and removing the .bak extension from the backup.

Remove system bloat

This step is intended to remove programs that may be on the system by defualt that are not required. To remove them, a text file can be created containing a list of programs to be removed. When the script is run... it will read this list and remove all the programs on it.

Commands
The following commands can be used

Add home directories and dot-files

Populate home directory from backup.

Commands
The following commands can be used

Install Repository Packages

Install packages from list

Commands
The following commands can be used

Install Local Packages (.debs)

Install .deb packages from .packages directory

Commands
The following commands can be used

Configure .bashrc

Add to the file

Commands
The following commands can be used

Configure installed packages

Due to the fact most of these configurations are typically done through a GUI interface and cannot be done within the script... we can provide notes that may have been taken on how to configure these applications

Commands
The following commands can be used

Clean up the system

Now that the system has been updated and all necessary packages have been installed... all that is left to do, is to clean up the system. This will remove any left over packages that are no longer required and older kernels that may have been replaced during the initial upgrade.

Commands
The following commands can be used

Write Script

To write the script... all that is left to do is to copy and paste all of the commands found above and add some fluff to make it presentale to the user (us) when the script is run. Shown below is an example. This example can be copy and pasted into a text editor and saved.

The very 1st line of the script points to where bash is installed on the system. If this is different in your case, the following command can be used to find this path.

Script example
example shown below

#!/usr/bin/bash

# welcome
echo ""
echo "welcome to post-install.sh"
echo ""
sleep 2

# 0. get the backup path
echo "Enter the backup path below [/media/$USER/BACKUP/home/]"
read BACKUP
sleep 2
echo ""
echo "backup path provided: $BACKUP"
sleep 1
read -p "<enter> to continue"
clear
echo ""

# 1. backup '.bashrc', .'profile', 'sources.list'
echo "backing up important dot-files..."
sleep 2
sudo cp ~/.bashrc ~/.bashrc.bak
sudo cp ~/.profile ~/.profile.bak
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 2. remove system bloat
echo "removing system bloat..."
sleep 2
sudo apt purge -y $(cat /media/$USER/POST-INSTL/lists/bloat.list)
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 3. add home directories and dot files
echo "adding home directories..."
sleep 2
cp -r $BACKUP/. /home/$USER/
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 4. install repository packages
echo "adding repository packages..."
sleep 2
sudo apt update
sudo apt install -y $(cat /media/$USER/POST-INSTL/lists/apt.list)
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 5. install local packages
echo "adding local packages..."
sleep 2
sudo dpkg -i ~/.packages/*.deb
sleep 2
echo ""
echo "adding missing dependencies"
echo ""
sudo apt install -f
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 6. configure '.bashrc'
echo "adding .bashrc configurations"
sleep 2
cat /media/$USER/POST-INSTL/docs/system/bashrc_extras.txt >> ~/.bashrc
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# 7. configure installed packages
echo "configure installed packages..."
sleep 2
ls /media/$USER/POST-INSTL/docs/packages/
echo ""
echo "refer to documentation provided above"
read -p "<enter> to continue"
clear
echo ""

# 8. cleanup the system
echo "cleaning up the system..."
sleep 2
sudo apt autoremove
echo ""
echo "done."
read -p "<enter> to continue"
clear
echo ""

# exit
echo "system configuration complete!"
echo ""
read -p "<enter> to exit"
sleep 2
echo "goodbye"
sleep 2
exit

Edit Files

Before the script is run, we will first need to edit the files that were created in prevous steps. Such as apt.list, bloat.list and bashrc_extras.txt. Examples shown below

lists/apt.list
Example of file contents

lists/bloat.list
Example of file contents

docs/system/bashrc_extras.txt
Example of file contents

# prompt (variables)
red=$(tput setaf 95)
navajo=$(tput setaf 144)
green=$(tput setaf 118)
bold=$(tput bold)
reset=$(tput sgr0)

# prompt (construct)
PS1="\n";
PS1+="\[${bold}\]";
PS1+="\[${red}\]fossman";
PS1+="\[${navajo}\]@";
PS1+="\[${red}\]\h";
PS1+="\[${navajo}\] [\w]";
PS1+="\n";
PS1+="\[${navajo}\] > ";
PS1+="\[${reset}\]";

# Custom Variables
STACK='/media/$USER/MAIN-STACK/'
RESOURCES='/media/$USER/MAIN-STACK/Resources/'

# Environment Variables (Bash and Python)
export PATH=$PATH:~/Modules/Bash
export PATH=$PATH:~/Modules/Python
export PATH=$PATH:~/Modules/Python/Drivers

Run Script

Finally... it's time to run the script.
Use the command shown below to launch the script. Due to the fact absolute paths and system variables were used in place of usernames, it can be run from anywhere in your terminal.

Run script
The following command can be used

Post actions
Reboot when finished
