Git - Slack integration

• Create incoming web hook on slack by going to https://lcsweb.slack.com/services

• cd to your bare repo eg:project.git and cd to hooks and create post-receive hook
• Add bash commands to push related information to slack. (You can find many bash scripts published in the internet or you can write your own script referring following parameters in the post-receive hook.
  

  oldrev
  newrev
  refname

• Give permission 

chmod +x post-receive

• cd to your bare repo eg:project.git and execute following commands

git config -f config hooks.slack.webhook-url 'https://hooks.slack.com/services/xxx.....'

git config hooks.slack.channel '#development-xxx'

Get latest from Git Master to other branch

git fetch origin
git checkout master
git merge origin/master

To switch to your branch, just do
git checkout branch1

Merge a git branch into master

git checkout master
git pull origin master
git merge test(branch name)
git push origin master

Adding an existing project to GitHub

Initialize the local directory as a Git repository.
git init

Add the files in your new local repository. This stages them for the first commit.
git add .

Commit the files that you've staged in your local repository.
git commit -m 'First commit'

In the Command prompt, add the URL for the remote repository where your local repository will be pushed.
git remote add origin https://ishara@bitbucket.org/ishara/weatherapp.git
# Sets the new remote
git remote -v
# Verifies the new remote URL

GitHub for Windows users should use the command git remote set-url origin instead of git remote add origin here.

git push origin master
