The latest of my forgetful commands. A few chmods for running npm and cutting back on arbitrary sudo needs.
sudo chown -R $USER /usr/local/bin sudo chown -R $USER /usr/local/lib/node_modules
…and every once in a while the stupid npm directory will get hosed up, which can often be fixed with.
sudo chown -R $USER /Users/adron/.npm/*
One command I always forget is what the switches are for creating an ssh key.
ssh-keygen -t rsa -C "email@example.com"
There is also the case of making the directory with appropriate permissions to then create the ssh key.
mkdir ~/.ssh chmod 700 ~/.ssh/ ssh-keygen -t rsa
More information, specific to github, can be found in this documentation.

If there’s ever a file you need to remove from git history for whatever reason (accidentally included a password or API Key, removing large files, etc), the below will remove it from the history of every branch and every tag. For example, to remove a file named “config.yml”
git filter-branch -index-filter 'git rm –cached –ignore-unmatch config.yml' –prune-empty –tag-name-filter cat – –all
For more info on this command, check out the link to the github doc.
Delete Local Branch
git branch -d the_local_branch
Delete Remote Branch
git push origin --delete
git push origin :
To synchronize your branches once a delete has occurred you sometimes may need to issue the following fetch command.
git fetch -p
Getting a Remote Branch
git checkout -b new_local_branch origin/existing_remote_branch
…and last but not least, the forgotten remote branch delete command.
git push origin --delete serverfix
Keygen on Windows for Powershell with OpenSSH.
Ensure OpenSSH is installed. First open up DOS or the PowerShell terminal (NOT ISE) with “As an administrator”.
Now just issue the keygen command listed above in the other example!

One I hate that when I have to use, but always need to look it up. If there’s ever a file you need to remove from git history for whatever reason (accidentally included a password or API Key, removing large files, etc), the below will remove it from the history of every branch and every tag. For example, to remove a file named “config.yml”…
git filter-branch -index-filter ‘git rm –cached –ignore-unmatch config.yml’ –prune-empty –tag-name-filter cat – –all
Holy smoley… that’s a string of em’ for sure!
