Git Commands & Info

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 "your_email@youremail.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.

Brian McClain (@BrianMMcClain) added from the comments below:

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.

Branch Management

Delete Local Branch

git branch -d the_local_branch

Delete Remote Branch

git push origin --delete

or

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!
