git create new branch on server, pull to client

# ON CENTRAL SERVER
git checkout master # as needed; we are assuming that master is clean enough as a starting point
git checkout -b mynewbranchy

# HOWEVER, use this instead if you need a new "clean" repo and even master is dirty...
# You need the rm because git "leaves your working folder intact".
git checkout --orphan mynewbranchy
git rm -rf .

# ON CLIENT
git pull
git checkout -b mynewbranchy origin/mynewbranchy
# if files are in the way from the previously checked-out branch, you can force it...
git checkout -f -b mynewbranchy origin/mynewbranchy

git pull when untracked files are in the way
This will pull, forcing untracked files to be overwritten by newly tracked ones in the repo: git fetch --all git reset --hard origin/mymatchingbranch

git create new branch when untracked files are in the way

  git checkout -b bj143 origin/bj143
     git : error: The following untracked working tree files would be overwritten by checkout:
     (etc)
  
  TOTAL PURGE FIX (too much):
     git clean  -d  -fn ""
        -d dirs too
        -f force, required
        -x include ignored files (don't use this)
        -n dry run
  
  BEST FIX (just overwrite what is in the way):
     git checkout -f -b bj143 origin/bj143

git recreate repo

git clone ssh://m@thedigitalmachine.com/home/m/development/thedigitalage/ampache-with-hangthedj-module
cd ampache-with-hangthedj-module
git checkout -b daily_grind origin/daily_grind

If you already have the daily_grind branches and just need to connect them:

git branch -u origin/daily_grind daily_grind

git connect to origin after the fact

git remote add origin ssh:// m@bitpost.com/home/m/development/logs
git fetch
    From ssh:// bitpost/home/m/development/logs
     * [new branch]      daily_grind -> origin/daily_grind
     * [new branch]      master     -> origin/master
git branch -u origin/daily_grind daily_grind
git checkout master
git branch -u origin/master master

git multiple upstreams
Use this to cause AUTOMATIC push/pull to a second origin: git remote set-url origin --push --add user1@repo1 git remote set-url origin --push --add user2@repo2 git remote -v show Leave out --push if you want to pull as well... but I'd be careful, it's better if code is changed in one client with this config, and then pushed to the multiple origins from there. Otherwise, things are GOING TO GET SYNCY-STINKY.

CONFIGURATION

git convert to a bare repo
Start with a normal git repo via [git init]; add your files, get it all set up. Then do this: cd repo Now you can copy-paste this... mv .git .. && rm -fr * mv ../.git . mv .git/* . rmdir .git git config --bool core.bare true cd .. Don't copy/paste these, you need to change repo name... mv repo repo.git # rename it for clarity git clone repo.git # (optional, if you want a live repo on the server where you have the bare repo) Then you can clean up old branches like daily and daily_grind, as needed.

git merge --strategy-option theirs

git create merge-to command
Add this handy alias command to all git repos' .config file... [alias] merge-to = "!gitmergeto() { export tmp_branch=`git branch \| grep '* ' \| tr -d '* '` && git checkout $1 && git merge $tmp_branch && git checkout $tmp_branch; unset tmp_branch; }; gitmergeto"

git fix github diverge from local bare repo following README.md edit
Yes editing the README.md file on github will FUCK UP your downstream bare repo if you meanwhile push to it before pulling. Fixing it is a PAIN in the ASS, you have to create a new local repo and pull github into that, pull in from your other local repo, push to github, pull to your bare... git clone git@github.com:moodboom/quick-http.git quick-http-with-readme-conflict git remote add local ../quick-http git fetch local git merge local/master # merge in changes, likely trivial git push # pushes back to github cd .. mv quick-http.git quick-http.git__gone-out-of-sync-fu-github-readme-editor git clone git@github.com:moodboom/quick-http.git --bare cp quick-http.git__gone-out-of-sync-fu-github-readme-editor/config quick-http.git/ And that MIGHT get you on your way... but I would no longer trust ANY of your local repos... This is a serious pita.

git use kdiff3 as difftool and mergetool

It's been made easy on linux...

LINUX - put this in ~/.gitconfig

[diff]
    tool = kdiff3

[merge]
    tool = kdiff3

WINDOZE

[difftool "kdiff3"]
    path = C:/Progra~1/KDiff3/kdiff3.exe
    trustExitCode = false
[difftool]
    prompt = false
[diff]
    tool = kdiff3
[mergetool "kdiff3"]
    path = C:/Progra~1/KDiff3/kdiff3.exe
    trustExitCode = false
[mergetool]
    keepBackup = false
[merge]
    tool = kdiff3

LINUX Before - What a ridiculous pita... copy this into .git/config...

[difftool "kdiff3"]
    path = /usr/bin/kdiff3
    trustExitCode = false
[difftool]
    prompt = false
[diff]
    tool = kdiff3
[mergetool "kdiff3"]
    path = /usr/bin/kdiff3
    trustExitCode = false
[mergetool]
    keepBackup = false
[merge]
    tool = kdiff3

git windows configure notepad++ editor
git config --global core.editor "'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"

git fix push behavior - ONLY PUSH CURRENT doh
git config --global push.default current

From here...
