How to undo a Git commit that was not pushed

Method 1: Undo commit and keep all files staged In case you just want to undo the commit and change nothing more, you can use

git reset --soft HEAD~;

Moving to an existing branch

If you want to move your commits to an existing branch, it will look like this:

git checkout existingbranch
git merge master         # Bring the commits here
git checkout master
git reset --keep HEAD~3  # Move master back by 3 commits.
git checkout existingbranch

The --keep option preserves any uncommitted changes that you might have in unrelated files, or aborts if those changes would have to be overwritten -- similarly to what git checkout does. If it aborts, git stash your changes and retry, or use --hard to lose the changes (even from files that didn't change between the commits!)

Change git username and email

To set your global username/email configuration

git config --global user.name "FIRST_NAME LAST_NAME"
git config --global user.email "[email protected]"

To set repository-specific username/email configuration:

Git: Stash unstaged changes

This will stash all modifications that you did not git add:

git stash -k

Note that newly created (and non-added) files will remain in your working directory unless you also use the -u switch.

git stash -k -u

Git: Remove files after updating .gitignore

Here, we're removing all files that are currently being ignored in .gitignore:

git rm -r --cached .
git add .
git commit -m "Removes all .gitignore files and folders"

Flutter: Create project, library or plugin

create project

flutter create --org com.example.project.name  --androidx -i swift -a kotlin --description 'Description goes here' flutter_project_name

create library/package

flutter create --org com.example.package.name  --description 'Description goes here' --template=package flutter_package_name

create plugin

Dart: Create project

dart create -t console-simple project_name

Available templates:

console-simple: A simple command-line application. (default)
console-full: A command-line application sample.
package-simple: A starting point for Dart libraries or applications.
web-simple: A web app that uses only core Dart libraries.

-find . -name ".*" -print
-# I don't know the MAC OS, but that is how you find them all in most *nix environments.
-find . -name ".*" -exec rm -rf {} \;
-# to get rid of them... do the first find and make sure that list is what you want before you delete them all.
-# The first "." means from your current directory. Also note the second ".*" can be changed to ".svn*" or any other more specific name; the syntax above just finds all hidden files, but you can be more selective. I use this all the time to remove all of the .svn directories in old code.
