Use two different accounts on Github CLI

README.md

~/.gitconfig

[filter "lfs"]
        clean = git-lfs clean -- %f
        smudge = git-lfs smudge -- %f
        process = git-lfs filter-process
        required = true
[user]
        name = Ganesh Satpute
        email = your-email@company.com

[includeIf "gitdir:~/code/personal/"]
    path = ~/code/personal/.gitconfig

~/code/personal/.gitconfig

[user]
        name = Ganesh Satpute
        email = personal@gmail.com

Is this required? ~/.ssh/config

Host github.com
  User git
  IdentityFile ~/.ssh/id_ed25519

Host github.com-github-personal
  HostName github.com
  User git
  IdentityFile ~/.ssh/github-personal

You need to have two keys configured on respective Github accounts and be present in .ssh directory.
