Setup ansible environment with the following directory structure.

Use Git Grep to Replace Strings in Files in Your Git Repository

On Linux:

git grep -l 'original_text' | xargs sed -i 's/original_text/new_text/g'
On Mac:

git grep -l 'original_text' | xargs sed -i '' -e 's/original_text/new_text/g'
I needed to change a string in a bunch of files and I used the command above using git grep to do it. Worked like a charm.

The -l argument to git grep only returns the file names and not the location in the file like it usually does.

The -e argument is needed with the sed portion on OSX as stated by asmeurer in the comments

How to make SSH agent running in the background

============================================================

ssh-agent: It is an authentication agent which handles all the private keys password. ssh-agent command initiates a ssh agent background program which we will be used later to store private keys password.You will notice the below output on terminal. Add the output in .bash_profile to always load it automatically.

SSH_AUTH_SOCK=/tmp/ssh-D6wit2Nad0zP/agent.7180; export SSH_AUTH_SOCK;
SSH_AGENT_PID=7181; export SSH_AGENT_PID;
echo Agent pid 7181;

After Provisioning the VM you need to install few packages like below

yum install kernel-devel
yum install gcc*
