I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.
git revert {commit_id}
Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:
// check version | |
node -v || node --version | |
// list locally installed versions of node | |
nvm ls | |
// list remove available versions of node | |
nvm ls-remote | |
// install specific version of node |

start new:
tmux
start new with session name:
git branch -m old_branch new_branch # Rename branch locally | |
git push origin :old_branch # Delete the old branch | |
git push --set-upstream origin new_branch # Push the new branch, set local branch to track the new remote |
Outdated note: the process is a lot easier now: after you brew install postgresql
you can initialize or stop the daemon with these commands: brew services start postgresql
or brew services stop postgresql
.
new out put may look like
To have launchd start postgresql now and restart at login:
brew services start postgresql
Or, if you don't want/need a background service you can just run:
pg_ctl -D /usr/local/var/postgres start
