Switching remote URLs


List your existing remotes in order to get the name of the remote you want to change.

$ git remote -v
origin  git@github.com:USERNAME/REPOSITORY.git (fetch)
origin  git@github.com:USERNAME/REPOSITORY.git (push)


Change your remote's URL 

$git remote set-url origin https://github.com/USERNAME/REPOSITORY.git

Verify that the remote URL has changed.

$git remote -v
# Verify new remote URL
origin  https://github.com/USERNAME/REPOSITORY.git (fetch)
origin  https://github.com/USERNAME/REPOSITORY.git (push)




//Add git autocompletion script to iterm
https://apple.stackexchange.com/questions/55875/git-auto-complete-for-branches-at-the-command-line

ok, so I needed the git autocompletion script.

I got that from this url:

curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash

No need to worry about what directory you're in when you run this as your home directory(~) is used with the target.

Then I added to my ~/.bash_profile file the following 'execute if it exists' code:

if [ -f ~/.git-completion.bash ]; then
  . ~/.git-completion.bash
fi


// Check where do the settings in my Git configuration come from

git config --list --show-origin


// fetch all local changes
git fetch --all

// bring local master up to date as upstream master
git merge upstream master

git push origin master

git reset --hard upstream/master

//set up stream

git remote -v

// get other's work

git checkout -b temp-branch

git fetch --all

git branch --all

git rebase #{remote-name}/#{branch-name}, e.g. git rebase mike/my-nice-branch

git cherry-pick #{a-git-sha}

// change a local branch's name, rename a local branch
git branch -m #{fancy-new-name}

// git verbose info of a branch
git branch -v
// git even more verbose info of a branch
git branch -vv

//
git branch --set-upstream-to #{remote-name}/#{branch-name}, e.g. git branch --set-upstream-to origin/my-awesome-feature-branch

// get other people's change onto a new branch
git checkout -b a-new-branch master
git pull https://github.com/#{user-name}/#{repo-name}.git #{branch-name}

//undo a git add
git reset #{file-path}

//undo a git commit that is already pushed to github
// situtation on my forked repo page This branch is 1 commit ahead of <the original repo>:master.

git reset <previous label or sha1>
git push -f <remote-name> <branch-name>

//remove untracked files (This can be dangerous!!! Your .env files might be gone!!!! )

To remove directories, run git clean -f -d or git clean -fd.
To remove ignored files, run git clean -f -X or git clean -fX.
To remove ignored and non-ignored files, run git clean -f -x or git clean -fx.

// add a remote. Use case, when more than 1 people is forking a branch, and you want to test other's changes
git remote add ${the-name-of-the-remote-to-track-others-work} ${the-CLONE-WITH-HTTPS-LINK-ON-GITHUB}
git fetch --all // get all the branches of the other people
git branch --all // take a look at all the branches

Removing a remote
Use the git remote rm command to remove a remote URL from your repository.

The git remote rm command takes one argument:

A remote name, for example, destination
Example
These examples assume you're cloning using HTTPS, which is recommended.


git remote -v
# View current remotes
origin  https://github.com/OWNER/REPOSITORY.git (fetch)
origin  https://github.com/OWNER/REPOSITORY.git (push)
destination  https://github.com/FORKER/REPOSITORY.git (fetch)
destination  https://github.com/FORKER/REPOSITORY.git (push)
git remote rm destination
# Remove remote
git remote -v
# Verify it's gone
origin  https://github.com/OWNER/REPOSITORY.git (fetch)
origin  https://github.com/OWNER/REPOSITORY.git (push)




// resolve a binary file conflict with Git
//warning: Cannot merge binary files: xxx/public/img/favicon.ico (HEAD vs. master)
//Auto-merging xxx/public/img/favicon.ico
//CONFLICT (add/add): Merge conflict in xxx/public/img/favicon.ico
(Reference link https://lostechies.com/joshuaflanagan/2010/01/29/how-to-resolve-a-binary-file-conflict-with-git/)
1) make a decision: keep the version of the file in your current branch, or the version in the other branch. 


1.a) Resolve using mine
The file in your working copy is still the copy from your current branch – in other words, it was not modified by the merge attempt. To resolve the conflict and keep this file:

$git add xxx/public/img/favicon.ico 
$git commit –m “My commit message for the merge”

1.b) Resolve using theirs

$git checkout otherbranch xxx/public/img/favicon.ico 
$git add xxx/public/img/favicon.ico 
$git commit –m “My commit message for the merge”

Add a file to the last commit in git?

$git add the_left_out_file
$git commit --amend --no-edit
