git

1) Git SSH configuation
Generate RSA key pair
  - ssh-keygen -t rsa -b 4096 -C "your_email@domain.com"
  - This generates 2 file, id_rsa and id_rsa.pub in ~/.ssh directory.
  - Copy the content of id_rsa.pub and configure in the git settings under the account details.

Then after opening terminal, always execute below 2 command to load the RSA private key (id_rsa).
After loading, all git commands can be executed without entering credentials every time.
   - eval $(ssh-agent -s)
   - ssh-add ~/.ssh/id_rsa

2) Git patching
git format-patch <master_branch> -o <dir>
git am <patch_file> 
  - This commits
git apply <patch_file> 
  - This modifies but does not commits

3) Git clone
git clone without verifying server cert
  - git config --global http.sslverify false
