"Means there is a change, asking you how to deal with the change# # No commits yet on master??index.html$ git add index.html//"git add index.html" adds the new "index.html" file to the staging area$ git STATUS-SB//"Git status-sb" again to see the changes in the file, the green "A" means adding a new file to the warehouse# # No commits yet on Mastera index.html$ git commit-M"my first time to submit"     //"Git commit-m" formally submits the file of the staging area to the local repository, which is the ".

2 How to get an SSH key

• Why do I need to get SSH key? -Because SSH key allows access to all of your warehouses.
• How many SSH keys does a computer need? -Each computer needs only one.
• How do I get ssh key? --refer to the following steps:

  *To get the SSH key step:*sign in to GitHub*Click the avatar in the top right corner of the page*select Setting*Select SSH and GPG keys*Click Generating SSH keys* Click Generating a new SSH key and adding it to thessh-agent* Copy the first black command of generating a new SSH key"ssh-keygen-t rsa-b 4096-c"[Email protected]""to Gitbash (or terminal)*enter three times and then get a bubble-like thing that means it 's done.* then enter"Cat ~/.ssh/id_rsa.pub", get a bunch of English, copy this paragraph of English* Go back to the 4th step of the page and click on the green button in the top right corner"New SSH Key"*put what you just copied into the text box below the key, edit a title casually, click the green button below to confirm the addition* Back to Git Bash (terminal), run"ssh-t [email protected]"Test is successful, get a hint to get you back to yes/No, enter Yes to return* If you get"Permission denied (publickey)", unfortunately, you have failed and need to start again from the first step;"You ' ve successfully authenticated", then congratulations, you made it.

• Tips: If you already have SSH key and need to be re-added, you can run "Rm-rf ~/.ssh/*" in Git Bash before doing the above steps to delete the existing SSH key
• The pits that have been trampled:

  * in"ssh-t [email protected]"When you encounter code such as the opening parenthesis, in general, enter"Ping github.com"can be resolved. (Error prompt:SSH: Could not resolvehostname[Github.com] (http://github.com): NodeName nor servname provided, or not known)
  
  * Input"git remote add origin [email protected]:nolaaaaa/yyy.git"When you encounter code such as the opening parenthesis, enter"git remote rm Origin"And then re-press the steps to lose"git remote add origin [email protected]:nolaaaaa/yyy.git""git push-u Origin master"can be. (Error Hint: Fatal:remote origin already exists.)
