################### Configurations ####################

# Make ssh connection with github (from Debian)

- Generate public/private key pair on local computer
cd ~/.ssh
ssh-keygen -t rsa -C "your_email@example.com"

- Add private key to the local ssh-agent
eval `ssh-agent -s`
ssh-add ~/.ssh/id_rsa

- Copy public key to clipboard
clip < ~/.ssh/id_rsa.pub - Linux
pbcopy < ~/.ssh/id_rsa.pub - Unix

- Add public key to Github
https://github.com/settings/ssh

- Check ssh connection with github
ssh -T git@github.com

# When git asking username and password every time you commit, then you have cloned the repository using https rather using ssh. To correct that mistake
git remote set-url origin git@github.com:dilumdarshana/AngularJS.git

# When git contribution does not show on the profile graph do this,
git config --global user.email "YOUR EMAIL ADDRESS"

# git config : To config settings
eg. git config --global user.name = 'Dilum Darshana';
git config --global user.email = 'dilum.dar@gmail.com';

# git reset HEAD <file name> : Remove added files from git (this can not reset files which committed)

# git checkout -- <file_name> : to discard current changes

---------- Branching -----------

# git branch <branch_name> : Create branch on local. Will switch to this branch automatically

# git branch : List down all local available branches

# git checkout <branch_name> : Switch to branch on local

# git checkout -b <branch_name> : Create new branch and switch into that

# git branch -m '<new_branch_name>' : Rename branch, when on the branch
# git push origin :<old_branch_name> <new_branch_name> : After rename, make remote branch change

# git branch -d <branch_name> : Delete branch

---------------- Stashing ----------------

# git stash : To stash away current changes

# git stash list : To list down all the available stashes

# git stash apply : To apply last stash to current repo

# git stash apply <stash identifier> : To apply specific stash. Stash identifier can take from 'git stash list'

# git stash drop : To destroy all stashes

------------ Tagging -----------------

# git tag -a <version_number> -m <comment> : Create a tag
git push --tags

 ------------ Merging ----------------

------------ Debugging -------------

# git log : To see git local history

# git show <git log ID> : to see the changes for given log ID

# git branch -v : to see what is the latest change for each branch

------------- Create Command shortcuts -----------

git config --global alias.s status : short form works for 'git s'

Note: these configurations will be stored in file located at '~/.gitconfig'

------------- Git Ignore -------------

# Ignoring files
Create a files with name .gitignore and add files/directories that need to ignore on that file
General set of files need to ignore for main projects can be found from
https://github.com/github/gitignore
