Working with git

Interacting with a remote repository

Check out a repository:

 git clone <remote-repo-url> <local-repo-name>
 git clone carpetgit@carpetcode.org:McLachlan McLachlan

Find out what changes were made to a remote repository:

 ???

Update from a repository, if there are no local uncommitted changes:

 git pull

How to merge?

Update from a repository, if there are local changes:

 git stash
Then update as described above
 git stash pop

If there are no conflicts, you are done. If there are conflicts, handle them, then

 git stash drop

since "stash pop" doesn't pop the stash if there are conflicts. "git stash list" shows all stashes. It is not possible to look at the content of a stash (???).

Push to a repository:

Ensure all remote changes have been pulled

 git push

Create a branch containing the current snapshop of the local repository, including all uncommitted changes, and switch to this branch

should this maybe be split into two actions: creating a remote branch, and switching to this branch locally?

Committing

Commit a change:

 git add <list-of-files-to-commit>
 git commit

Undo a commit that hasn't propagated yet, keeping all local changes:

 ??? (probably some variation of "git reset" and "git checkout")

Revert a commit that may have propagated already, keeping all the changes as local modifications:

 ???

Revert a commit, dropping all changes that it made:

 ??? (some variation of "git reset")

Making local changes

Revert an uncommitted change to a file:

 git checkout -- <file>

Add a file to the repository:

Create file locally

 git add <list-of-files-to-add>

Then commit.

Remove a file from the repository:

Delete file locally

 git rm <list-of-files-that-were-removed>

(Is there a way to let git determine automatically which files were removed?) Then commit.

Undo adding a file to the repository:

Delete file locally

 git reset HEAD <file>

Undo removing a file from the repository, recreating the file manually:

Create file locally

 git reset HEAD <file>

Undo removing a file from the repository, resurrecting the file in the repository:

 ??? (probably a combination of "checkout" and "reset")
