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

Basics

get some code:

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

for example to switch back to master:

git checkout master
