GIT COMMANDS

git-commands.sh

# CHECKOUT BRANCH
   $ checkout branch -f
   $ git pull

# CHECK CHANED FILES IN GIT COMMIT:
   $ git log
   $ git log -p -2
   $ git log --pretty=oneline
   $ git log --name-only
   $ git log -1 --stat
   $ git log --graph
   $ git log --graph --oneline
   $ git log --graph --oneline --branches
   $ git show --pretty="format:" --name-only 6ef288287c49e21062d8a9d9561d8f4a635bbf15
   $ git show --summary
   
   # or
   $ git diff-tree --no-commit-id --name-only -r 7dc1fc210f9608e3eacdcb4f9549cf84379a3ff6

   # Notes:
   # The --no-commit-id suppresses the commit ID output.
   # The --pretty argument specifies an empty format string to avoid the cruft at the beginning.
   # The --name-only argument shows only the file names that were affected (Thanks Hank).
   # The -r argument is to recurse into sub-trees

# MOVE FILES TO ANOTHER DIRECTORY:
   $ mkdir lib
   $ git mv hello.html lib
   $ git status

# DIFFERENCE BETWEEN git pull AND git fetch: Fetching and Pulling from Your Remotes
   # git fetch command pulls the data to your local repository – it doesn’t automatically merge it with any of your work or modify what you’re currently working on. You have to merge it manually into your work when you’re ready.
   # git pull command to automatically 'git fetch' and then 'git merge' a remote branch into your current branch.

# UNDO 'git add' BEFORE COMMIT:
   # I mistakenly added files using the command:
   $ git add filename
   
   # Undo git add before commit with:
   $ git reset filename
   
   # To remove everything and start again (recursive):
   $ git rm -r --cached .
   
   # To do a dry run and see what will be added:
   $ git add -n .

# To remove a file from the repo and not delete it from the local file system:
# 1. For a file:
   $ git rm --cached file.txt
   
# 2. For a directory:
   $ git rm --cached -r mydirectory

# To remove a file from de repo but also deletes it from the local file system:
   $ git rm file1.txt
   $ git commit -m "remove file1.txt"

# How to convert a normal Git repository to a bare one?
   $ cd repo
   $ mv .git .. && rm -fr *
   $ mv ../.git .
   $ mv .git/* .
   $ rmdir .git

   $ git config --bool core.bare true
   $ cd ..; mv repo repo.git # renaming just for clarity
   # Note that this is different from doing a git clone --bare to a new location (see below).

# ADDING REMOTE REPOSITORY:
   $ git remote
   origin
   
   $ git remote add pb https://github.com/paulboone/ticgit
   $ git remote -v

# PUSHING TO REMOTE REPO:
   $ git push <remote_name> <branch_name>
   $ git push origin master

# INSPECTING REMOTE:
   $ git remote show origin
   $ git remote
   $ git remote -v

# REMOVING AND RENAMING REMOTES:
   # I want to rename pb to paul:
   $ git remote rename pb paul
   $ git remote
      origin
      paul
   # NOTE: It’s worth mentioning that this changes your remote branch names, too.
   # What used to be referenced at pb/master is now at paul/master.
   
   # If you want to remove a remote for some reason
   $ git remote rm paul
   $ git remote
   origin
