My custom configuration scripts and tricks

1. Customise your Bash Prompt

   
   • To apply this theme open your bash config

   nano ~/.bashrc
   # you may use any text editor e.g - vim
   vim ~/.bashrc

   • Copy the contents of custom_prompt.sh to the end of .bashrc.
   • Save config file and exit

   # for nano 
   Ctrl + O 
   Enter
   Ctrl + X
   # for vim
   :w
   :q

   • Relaunch terminal or run following command

   source ~/.bashrc

   • You can change colors and add others options too, currently it shows time, user@host, current directory, active git branch,conda virtual environment and cute little emojis showing the success of last command. (😎:😩), Some terminals may not support emojis, replace with :) and :( in that case

2. Customise your PowerShell prompt

   
   • Set script execution policy, open a powershell with admin

   Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force

   • To apply this prompt you first need to find if there is an existing configuration

   if (!(Test-Path -Path $PROFILE)){ New-Item -Path $PROFILE -ItemType File } ; notepad $PROFILE

   • Copy the contents of profile.ps1 to this file, save and exit
   • Relaunch your powershell

3. Rebase and sqash commits of an active pull request (git)

   • Confirm or configure upstream

   # make sure you have a upstream configured, to check type 
   git remote -v
   # result will have origin and upstream as below
       origin  https://github.com/<you>/<repo>.git (fetch)
       origin  https://github.com/<you>/<repo>.git (push)
       upstream        https://github.com/<owner>/<repo>.git (fetch)
       upstream        https://github.com/<owner>/<repo>.git (push)

   If yes skip next step

   • Add a upstream

   git remote add upstream https://github.com/<owner>/<repo>.git

   Again check with previous command

   • Update your fork

   # fetch updates from upstream
   git fetch upstream
   # checkout master or main branch
   git checkout master
   # push update to your fork
   git push

   • Rebase your pull request, checkout the original branch used to create pull request

   git checkout pull-request-branch
   # rebase this branch
   git rebase upstream/master

   If you want to sqash your commits then follow the step or skip to last

   • reset last n commits

   git reset --soft HEAD~n
   # new sqashed commit
   git commit -m "commit message"

   • Push your changes

   git push origin +pull-request-branch

   + is required to put before branch name since you are rewriting the history and forcely pushing it

4. Split a commit in already pushed code or active pull request

   • Rebase last n commits

   git rebase -i HEAD~n

   In the interactive screen simply replace pick with edit in front of the commits you want to modify

   git reset HEAD~

   • Add your files again and commit

   git add ...
   git commit -m "commit 1 message"
   
   git add ...
   git commit -m "commit 2 message"
   .
   .
   git add ...
   git commit -m "last commit message"

   • Continue rebasing

   git rebase --continue

   • Push your changes

   git push origin +branch-name
