Configuring multiple ssh accounts for multiple git accounts (GitHub,GitLab,etc.)

config

# ~/.ssh/config
# Account 1
Host host1
HostName github.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_host1

# Account 2
Host host2
HostName gitlab.com
User git
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_host2

# Usages:
# git clone host1:<username/organization>/repo.git
# git clone host2:<username/organization>/repo.git

# Notes:
# You can also use this approach for logging in to other machines using ssh
# e.g. ssh host1
# Just be sure to configure the `User` option or specify it on cmd `ssh user@host1`
