GIT & SSH Snippets

sudo apt install git

git config --global user.name FooBar
git config --global user.email foo@bar.ch

# create new ssh key pair

ssh-keygen

cat ~/.ssh/id_rsa.pub

Restore SSH Keys ¹

1. Change the file permission

   sudo chown user:user ~/.ssh/id_rsa*
   sudo chmod 600 ~/.ssh/id_rsa
   sudo chmod 644 ~/.ssh/id_rsa.pub

2. (Re-)Start the ssh-agent

   exec ssh-agent bash

3. Add your SSH private key to the ssh-agent

   ssh-add ~/.ssh/id_rsa

Ignore changes from tracked files

Ignore all further changes, but you don't want git to remove current file from the repository:

git update-index --assume-unchanged <file>

... and reenable it again

git update-index --no-assume-unchanged <file>
