-v,verbose be more verbose

-progress force progress reporting
-
- Options related to merging
-r,rebase?false|true|preserve incorporate changes by rebasing rather than merging
-n! do not show a diffstat at the end of the merge
-stat show a diffstat at the end of the merge
-summary (synonym to --stat)
-log?n add (at most <n>) entries from shortlog to merge commit message
-squash create a single commit instead of doing a merge
-commit perform a commit if the merge succeeds (default)
-e,edit edit message before committing
-ff allow fast-forward
-ff-only! abort if fast-forward is not possible
-verify-signatures verify that the named commit has a valid GPG signature
-s,strategy=strategy merge strategy to use
-X,strategy-option=option option for selected merge strategy
-S,gpg-sign?key-id GPG sign commit
-
- Options related to fetching
-all fetch from all remotes
-a,append append to .git/FETCH_HEAD instead of overwriting
-upload-pack=path path to upload pack on remote end
-f,force force overwrite of local branch
-t,tags fetch all tags and associated objects
-p,prune prune remote-tracking branches no longer on remote
-recurse-submodules?on-demand control recursive fetching of submodules
-dry-run dry run
-k,keep keep downloaded pack
-depth=depth deepen history of shallow clone
-unshallow convert to a complete repository
-update-shallow accept refs that update .git/shallow
-refmap=refmap specify fetch refmap
