Cheatsheet — Git & GitHub

Using GitBash

Note: The tips below are tested under MS Windows.

Information about that is available in this GitHub article—Generating SSH keys.

If there are complication head to the GitHub troubleshooting article on the matter—Error: Permission denied (publickey).

However, you can follow this steps to generate an SSH key:

Generate a file with your ssh key (passphrase is optional, although, recommended):
```
 ssh-keygen -t rsa -C "[email protected]"
```
Add your new key to the ssh-agent:
1. Start ssh agent:
```
 ssh-agent -s
```
  or
```
 eval "ssh-agent -s"
```
  or
```
 eval "$(ssh-agent)"
```
  Tip: On my end, the eval "ssh-agent -s" and eval "$(ssh-agent)" always do the job.
2. Add the key to the ssh agent:
  
  The file generated is available in the root folder, where GitBash has been started. Therefore, you need to use this file.
  
  Note: The generated files are two - [FileName] and [FileName].pub.
```
	ssh-add [FileName]
```
  or
```
	eval "ssh-add [FileName]"
```
Add your ssh key to your GitHUb account:
1. Remember the generated [FileName].pub file? Use the following command to copy the ssh key to your clipboard:
```
 clip < [FileName].pub
```
2. Head to your GirHub account;
3. Go to settings ;
4. Go to SSH Keys section;
5. Press the Add SSH key button—
6. A form will appear below, type a title and paste the key in the textarea below:
7. Add the key by using the green Add key button below.
Test the connection
```
 ssh -T [email protected]
```

Staging is used to prepare a commit or a stash.

Staging all changes:
```
  git add -A	
```
or
```
  git add --a
```
Staging a file:
```
  git add filename.ext
```
Tip: With Tab key GitBash will list all files and folders available for staging.
Staging an entire folder (and all file within):
```
  git add controls/ajax/
```

Now, you can either commit or stash the staged files.
