Tips and Tricks

when making a new repo that will "receive" stuff use --bare

ssh server
user@server$ cd /data/gitroot
user@server$ git init --bare mynewproject
ssh desktop
user@desktop$ cd /home/david/work
user@desktop$ git init mynewproject
user@desktop$ touch myfile && git add myfile && git commit -m "initial import"
user@desktop$ git remote add origin ssh://user@server:/data/gitroot/mynewproject
user@desktop$ git push -u origin master

If you do not "git init --bare projectname" on the server then you might get something like this:

david@keres ~ $ git push -u origin master

remote: error:
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you

error: failed to push some refs to '/data/gitroot/home'

Basics

get some code:

git clone username@gitserver:/srv/gitroot/ugo-project.git

branches

list branches

git branch

make a new branch

git branch <newbranchname>

switch between branches

git checkout <branchname>

for example to switch back to master:

git checkout master

Maintenance

Backup

Clean up

taking all branches from remote and sending them to another

ensure that you have defiend both source and destination remotes in your local repo.

git remote -v 
source url (fetch)
source url (push)
destination url (fetch)
destination url (push)

then do it like this:

git push destintion refs/remotes/source/*:refs/heads/*
