Git

Basic Workflow

• Git clone the repo you are interested in:

git clone https://github.com/jtaubs1/OSCP-Prep.git

• Now move into the directory that the reposity or now located in and initialize the repo

git init

• For any site that is going to be hosted on GitHub pages, ensure you check out the gh-pages branch

git checkout -b gh-pages

• Now make all the chages you want to make on the repo.

• To see the status of the files changed before pushing the new commits.

git status

• If these are the changes you want to make:

git add .

• Now commit the changes locally

git commit -m "initial commit"

• You only have to do the below command once, but this will instruct git where to push the changes to:

git remote add origin https://github.com/jtaubs1/jtaubs1.github.io.git

• Now make the commit official and push to your branch:

git push origin gh-pages

Observing a Repository

• List new or modified files not yet commited

git status

• Show the changes to files not yet staged

git diff    

• Show the changes to staged files

git diff --cached

• Show all staged and unstaged file changes

git diff HEAD 

• Show the changes between two commit ids

git diff <commit1> <commit2>

• List the change dates and authoris for a file

git blame <file>

• Show the file changes for a commit id and/or file

git show <commit>:<file>

• Show full change history

git log

• Show change history for file/directory including diffs

git log -p [file/directory]

Working with Branches

• List all local branches

git branch

• List all branches local and remote

git branch -av 

• Switch to a branch, my_branch, and update working directory

git checkout my_branch

• Create a new branch called my_branch

git branch my_branch

• Delete the branch called my_branch

git branch -d my_branch

• Merge branch_a into branch_b

git checkout branch_b
git merge branch_a

• Tage the current commit

git tag my_tag

Make a Change

• Stages the file, ready for commit

git add [file]

• Stage all changed files, ready for commit

git add .

• Commit all staged files to versioned history

git commit -m "commit message"

• Commit all your tracked files to versioned history

git commit -am "commit message"

• Unstages file, keeping the file changes

git reset [file]

• Revert everything to the last commit

git reset --hard 

Synchronize

• Get the latest changes from origin (no merge)

git fetch

• Fetch the latest changes from origin and merge

git pull

• Fetch the latest changes from origin and rebase

git pull --rebase

• Push local changes to the origin

git push

Searching for Secrets in History

Clone repos and search commit history for leaked credentials:

git clone http://TARGET:3000/user/repo.git
cd repo

# View commit history
git log --oneline

# Check specific commit
git show COMMIT_HASH

# Diff between commits
git diff COMMIT1 COMMIT2

# Search for secrets in history
git log -p | grep -i password
git log -p | grep -i secret
git log -p | grep -i api_key
git log -p | grep -i token
