This show origin and upstream remotes

git remote -v
git remote show origin #shows branches, tags etc.
git remote show upstream #shows branches, tags etc.

(vs origin remote)

git remote add upstream git@github.com:username/git-repo.git

Remove a remote file or directory from a Git repository without deleting it from the local filesystem

For single file: #

git rm --cached myremotefiletodelete.log
git commit -m "remove file from repo"
git push

For single directory: #

git rm --cached -r myremotedirectortytodelete
git commit -m "remove folder from repo"

git log --pretty=format:"%h - %an, %ar : %s"

Changing old commit messages #

git rebase -i HEAD~3

Then this prompt pops up

pick f45c433 update readme 
pick e023d22 edit README
pick c245d34 init readme

# Rebase 9fdb3bd..f7fde4a onto 9fdb3bd
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
#
# These lines can be re- ordered; they are executed from top to
bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out

Then replace pick with reword. Save and close.

Finih with git push force:

git push --force
