Git Stuff

Linux

Configure ssh for github

To generate ssh keys see here Linux or Windows With ssh key add. Works only for github, when you need to access github enterprise servers this needs adjustment.

Host github.com
  IdentityFile ~/.ssh/githubkey

Tagging

git tag v1.0
git push --tags

CodeCommit

ssh config for AWS code commit

Host git-codecommit.*.amazonaws.com
  User ABCEDEUserKey
  IdentityFile ~/.ssh/privateKey

So that the ssh key gets used when cloning repositories. Create new GPG key without gui prompts, see also Docs

gpg --default-new-key-algo rsa4096 --gen-key --passphrase '' --pinentry-mode=loopback
gpg --list-keys
gpg --armor --export KEYID1234567890ABCDEF

Add the exported Key in Github under Settings > SSH and GPG Keys at New GPG Key Configuring git to use the key for signing

git config --global user.email "[email protected]"
git config --global user.name "Martin Feineis"
git config --global user.signingkey KEYID1234567890ABCDEF
git config --global commit.gpgsign true

Config File at ~/.gitconfig

[user]
	email = [email protected]
	name = Martin Feineis
	signingkey = KEYID1234567890ABCDEF
[commit]
	gpgsign = true

gh cli

Command reference Installation, also see installation more documentation, here

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg && sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg && echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null && sudo apt update && sudo apt install gh -y

list repos

gh repo list

Create a public repository and set it up to sync with git in the current directory

gh repo create -s=. --public --remote=upstream
git remote add origin [email protected]:<owner>/<project>.git
git branch -M main
git push -u origin main

the gh command creates a repo with the source (s) at the current directory, makes it public and pushes it to github.

Rewriting history

Checkout the commit you want keep, if you want to wipe everythin checkout the initial commit. Then reset the HEAD to this commit and force push it.

git checkout 1a2b3c
git reset --hard origin/master
git commit -am "rewriting history"
git push --force origin HEAD:master

Windows

Install git

Invoke-WebRequest -Uri "https://github.com/git-for-windows/git/releases/download/v2.43.0.windows.1/Git-2.43.0-64-bit.exe" -OutFile "~\Downloads\git.exe"
.\Downloads\git.exe

Generate SSH Key

The -N flag needs to be double quoted in Powershell

ssh-keygen -t rsa -b 2048 -C "HoneyLapGitHub" -f $HOME\.ssh\github -N '""'

GPG for Git

Invoke-WebRequest -Uri "https://files.gpg4win.org/gpg4win-4.2.0.exe" -OutFile "~\Downloads\gpg4win.exe"
   6 .\Downloads\gpg4win.exe

GPG for Git

Install GPG4win

gpg --default-new-key-algo rsa4096 --gen-key --passphrase '' --pinentry-mode=loopback
