git – Uly.me

Here’s the permission needed for an AWS user to manage their own IAM account. The policy allows them to view their own account information, change their own passwords, rotate access keys and certificates, and manage their own git credentials.

XCode after Catalina Upgrade

I tried running git after the Mac OS Catalina upgrade and got this error.

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools),
missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

Here’s the fix. For some very odd reason, Apple does not automatically reinstall xcode after each Mac OS upgrade.

You will need to either reset it or install it again.

# Try reset first
xcode-select --reset
# Or install it if reset doesn't work
xcode-select --install

Close your terminal, and reopen and run git again.

Git Diff Head

Here’s how to check what’s changed in your local Git repo vs the master repo.

Git Status tells you what file has changed, but not to the level of detail such as what lines or what code was changed.

Storing Git Credentials

There are two ways to store git credentials. One is temporary and the other permanent. You can store your git credentials unencrypted on disk forever or in cache memory temporarily.

Temporary. Store for 15 minutes.

git config credential.helper 'cache --timeout=900'

Permanent.

git config credential.helper store
git push http://example.com/repo.git
Username: <type your username>
Password: <type your password>

Next time you use git, you will not be prompted for a password.
