git cheat-sheet

The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/

A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by functional category:

Current state

Syntax and core concepts

Basic Syntax

Single-line comments are started with //. Multi-line comments are started with /* and ended with */.
C# uses braces ({ and }) instead of indentation to organize code into blocks. If a block is a single line, the braces can be omitted. For example,

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Git Cheat Sheet

Initial Setup

Initialize a repo

Create an empty git repo or reinitialize an existing one

git init

This is taken from here. http://stackoverflow.com/questions/67699/how-do-i-clone-all-remote-branches-with-git/72156#72156 Want this as a gist because I always come back to this posting.

First, clone a remote git repository and cd into it:

$ git clone git://example.com/myproject
$ cd myproject

Next, look at the local branches in your repository:
