There is a git repository at ssh://bandit31-git@bandit.labs.overthewire.org/home/bandit31-git/repo via the port 2220. The password for the user bandit31-git is the same as for the user bandit31.

 

Clone the repository and find the password for the next level.

 

hint: git

 

이번에도 git clone인데 웬일로 bandit31서버에 새로운 파일이 있었습니다.

email과 username을 알려줬네요

우선 하던대로 repo 폴더를 clone해오겠습니다

This time your task is to push a file to the remote repository.

Details:
    File name: key.txt
    Content: 'May I come in?'
    Branch: master

 

 

 

읽어보니까 로컬 branch에 있는 master reference를 remote branch로 보내라고 하네요.

(텍스트 파일이름은 key.txt | 파일 내용은: May I come in?)

master branch 위치에서 key.txt를 만들어봅시다

┌──(miso㉿Miso)-[~/repo]
└─$ git branch -a
* master   <-- 이미 master에 있네요
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

┌──(miso㉿Miso)-[~/repo]
└─$ ls
key.txt  README.md

┌──(miso㉿Miso)-[~/repo]
└─$ cat key.txt
May I come in?

 

 

이걸 이제 remote branch에 보내야겠죠?

remote에 push 하려면 순서가

• add
• commit
• push

형식으로 진행하면 됩니다.

┌──(miso㉿Miso)-[~/repo]
└─$ git add -f key.txt

┌──(miso㉿Miso)-[~/repo]
└─$ git commit -m "text.txt push"
Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident name (for <miso@Miso.localdomain>) not allowed

 

 

명령어를 하나씩 봅시다

git add -f key.txt

key.txt 를 강제(-f)로 stage에 올리겠다는 명령어

(.gitignore 설정에서 텍스트 파일이나 특정 파일을 무시하게 설정 돼있을 때 이를 무시하기 위해 -f(force) 옵션을 씀)

 

git commit -m "key.txt remote push"

방금 stage에 올린 key.txt를 commit 할 것이고, 저장 메세지는 "key.txt remote push" 이걸로 하겠다.

 

그런데 commit을 하려고 했더니 제가 누군지 물어보네요 그래서 친절하게 알려준 명령어 대로 설정을 해줬습니다

┌──(miso㉿Miso)-[~/repo]
└─$ git commit -m "key.txt remote push"
Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident name (for <bandit31@overthewire.org>) not allowed


┌──(miso㉿Miso)-[~/repo]
└─$ git config --global user.name "bandit31"    <-- 이렇게

┌──(miso㉿Miso)-[~/repo]
└─$ git config --global user.email "bandit31@overthewire.org"  <-- 22

 

 

그리고 다시 commit 하면?

┌──(miso㉿Miso)-[~/repo]
└─$ git commit -m "key.txt remote push"

제가 쓴 메세지 대로 commit 됐죠?

 

 

마지막으로 push 해주면 됩니다
