This script is intentionally dry-run by default.

Expected remote names:

github

gitlab

codeberg

sourcehut

Commands that will run with --execute:

git fetch github --prune --tags

git push --mirror gitlab

git push --mirror codeberg

git push --mirror sourcehut

Review configured remotes first:

git remote -v

EOF

exit 0

fi

git remote get-url github >/dev/null

git fetch github --prune --tags

for remote in gitlab codeberg sourcehut; do

if git remote get-url "$remote" >/dev/null 2>&1; then

git push --mirror "$remote"

else

printf 'Skipping %s: remote is not configured.\n' "$remote"

fi
