how to setup git with ssh

git-ssh.sh

ssh-keygen -t rsa -b 4096 -C "gituser@email.com"

eval "$(ssh-agent -s)"

# if there is no 'config' file in ~/.ssh 
touch ~/.ssh/config
----------------------------------
# in file config, this will add ssh to keychain
----------------------------------
Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_rsa
----------------------------------
# else skip to
ssh-add -K ~/.ssh/id_rsa

# create private key
ssh-add -K ~/.ssh/id_rsa

# copy public key and paste in github
pbcopy < ~/.ssh/id_rsa.pub

# after git rsa use git clone or something
# you can verify cause github will be on known_hosts
cat ~/.ssh/known_hosts



# ---- GITLAB -------- #
ssh-keygen -t rsa -b 4096 -C "user@email.com"
pbcopy < ~/.ssh/id_rsa_gitlab.pub
# paste it in git ssh section
# test it
ssh -T git@gitlab.com
# if error run (v = verbose):
# ssh -Tv git@gitlab.com 

# now it should be in
cat ~/.ssh/known_hosts
