Procedures

Add, Undo Add

Add:

git add path/to/file
git add .

Undo add:

git reset HEAD -- path/to/file
git reset HEAD -- .

Just like git add, you can unstage files recursively by directory and so forth, so to unstage everything at once, run this from the root directory of your repository:

git reset HEAD -- .

Checkout another but do not touch the workdir

The following recipe works in Git guis as well.

Create a temporary branch:

git checkout -b temp

Make temp point to the same as the branch that you want to switch to. Don’t touch workdir:

git reset --soft TARGETBRANCH

Now branches temp and TARGETBRANCH point to the same commit. So you can just switch to the desired branch. And that’s the trick: Files in the workdir are not affected:

git checkout TARGETBRANCH

The temp branch isn’t needed any more and can be removed:

git branch -d temp

Search: https://www.google.de/search?q=git+switch+branch+keep+files

Fetch all branches

See StackOverflow

Checkout, create and track branches from origin:

git branch -r | \
   grep -v '\->' | \
   while read remote; do \
      git checkout ${remote} --track -b ${remote#origin/}; \
   done

Some other ways (not in one step):

# quit being on a branch
git checkout --detach

# fetch all branches from origin
git fetch origin '+refs/heads/*:refs/heads/*'

For all tags:

--tags

Set all upstreams:

git branch -r | \
   grep -v '\->' | \
   sed "s/origin\///" | \
   while read local; do \
      git branch --set-upstream-to="origin/${local}" "${local}"; \
   done

Or, set all upstreams:

git branch -r | \
   grep -v '\->' | \
   while read remote; do \
      git branch --set-upstream-to="${remote}" "${remote#origin/}"; \
   done

Later:

git fetch

Rebase, Squash

  • http://stackoverflow.com/questions/5189560/squash-my-last-x-commits-together-using-git

    If you want to write the new commit message from scratch, this suffices:

    git reset --soft HEAD~3 && git commit

    If you want to start editing the new commit message with a concatenation of the existing commit messages (i.e. similar to what a pick/squash/squash/…/squash git rebase -i instruction list would start you with), then you need to extract those messages and pass them to git commit:

    # --soft   reset pointer, but not files
# --edit   additionally open commit msg in editor

git reset --soft HEAD~3 && \
git commit --edit -m"$(git log --format=%B --reverse HEAD..HEAD@{1})"

# or, if mybranch has an upstream set:
git reset --soft HEAD~3 && \
git commit --edit -m"$(git log --format=%B --reverse HEAD..mybranch@{upstream})"

# like in
git commit --edit -m"$(git log --format=%B --reverse HEAD..devmarble@{upstream})"

During rebase:

git rebase --abort
git rebase --continue
git rebase --skip

Remove untracked files

Do a dry-run:

git clean -f -n

Remove:

git clean -f

Learn more at stackoverflow.

Revert changes

git checkout -- <filename>

git fetch origin
git reset --hard origin/master

Revert to a previous commit

Rewrite history if your commits are not pushed yet:

➜  git status
On branch master
Your branch is ahead of 'origin/master' by 7 commits.

➜  git reset --hard HEAD~7
HEAD ist jetzt at 4f0f998 [BUGFIX] Commit message

To revert already published commits: Leave them in the history. Create a new commit that exactly restores the former state. For example:

# Let's be in sync with origin
git pull

# Go back to a specific former commit and
# adjust the files accordingly
git reset --hard f414f31

# Go back in history 1 step to where we just came from
# Don't adjust files.
git reset --soft HEAD@{1}

# Make a commit with the former state of files.
git commit -m "Reverting to the state of the project at f414f31`

See also:

Check the history:

git reflog

Switch branch but keep local files

You cannot do this directly. In GIT terms you have to look at it from a different perspective. You should conceive the process as: (1) save files, (2) switch branch, (3) checkout only the files.

It can be done like this:

# create a temporary branch
git branch temp

# commit all files to temp
git add .
git commit -am "commit everything to branch temp"

# checkout the desired branch
git checkout master

# checkout ONLY the files from branch temp
git checkout temp -- .

# delete the temp branch
git branch -D temp

# end

Submodules

Documentation: https://git-scm.com/docs/git-submodule

Add local submodule (from Stackoverflow:

git rm --cached one two three
git submodule add `pwd`/one
git submodule add `pwd`/two
git submodule add `pwd`/three

Example of ‘foreach’:

git reset --hard
git submodule foreach --recursive "git reset --hard"

Useful “tricks”

git add -i            # add interactively
git commit --amend    # change commit message
git commit -m "[BUGFIX] Start multiline commit message

...continue with message
...continue with message
"                        <- finish message and start commit.

git pull --ff-only     # yes, fast forward only
git pull --rebase      # ?

git branch -va         # show all branches

git diff ABC BCD --name-only  # just list the name of different files

Which commits affect this file?

git log --follow FILESPEC

Working with Remotes

Add a remote source:

git remote add marble https://github.com/marble/typo3-upgradereport.git

Remove a remote source:

git remote remove marble

Pull from a foreign repo:

git remote -v
git remote add marble https://github.com/marble/typo3-upgradereport.git
git fetch marble
git checkout -b marble/marble-patch-1 --track marble/marble-patch-1
git remote -v

Create and check out branch from origin with tracking:

# Examples:
git checkout -t      origin/feature
git checkout --track origin/feature
git checkout --track origin/feature -b feature

Copy a clone to Non-Git version

cd /path/to/TYPO3.CMS
git checkout TYPO3_6-2
git pull
rsync -r --exclude="/.git" /path/to/TYPO3.CMS/  ~/htdocs/project/public_html/typo3_src-6.2dev

Which files and folders are currently in the cache?

What’s under version control?:

git ls-files

Which files and folders are currently being ignored?

Ignored files

http://stackoverflow.com/questions/466764/show-ignored-files-in-git

git ls-files --others   #!!!

Run both! One is not sufficient!:

echo "" >temp.log.txt
git ls-files --others --ignored --exclude-standard --directory  >>temp.log.txt
git ls-files --others --ignored --exclude-standard >>temp.log.txt
#

Branches

git config --local -l | grep branch

http://stackoverflow.com/questions/5162800/git-diff-between-cloned-and-original-remote-repository

# Add any remote repositories you want to compare:
git remote add foobar git://github.com/user/foobar.git

# Update your local copy of a remote:
# Fetch won't change your working copy.
git fetch foobar

# Compare any branch from your local repository to any remote you've added:
git diff [--name-status --name-only]  master foobar/master

# Delete remote branch
git push origin --delete <branchName>

Dmitry Dulepov writes:

If you work in a team, create many git branches and push them to the server, you may end up with many local branches that were merged and removed on the server. The following simple command will clean up your repository from local branches that track missing remote branches:

git fetch --all -p

Check your working tree

# Changes in the working tree not yet staged for the next co
# Changes between the index and your last commit;
# what you would be committing if you run "git commit" without "-a" option.
git diff --cached

# Changes in the working tree since your last commit; what you would be
# committing if you run "git commit -a"
git diff HEAD

Comparing with arbitrary commits

::

# Instead of the top of the current branch, compare with the top of “test” branch $ git diff test

# Instead of comparing with the top of “test” branch, compare with the top of the # current branch, but limit the comparison to the file “test”. $ git diff HEAD – ./test

# Compare the version before the last commit with the last commit. $ git diff HEAD^ HEAD

Comparing branches

# Changes between the tips of the topic and the master branches.
$ git diff topic master

# Same: Changes between the tips of the topic and the master branches.
$ git diff topic..master

# Changes that occurred on the master branch since when the topic branch was started off it.
$ git diff topic...master

Limit the diff output

# Show only modification, rename and copy, but not addition nor deletion.
$ git diff --diff-filter=MRC

# Show only names and the nature of change, but not actual diff output.
$ git diff --name-status

# Limit diff output to named subtrees.
$ git diff arch/i386 include/asm-i386

Munge the diff output

# Spend extra cycles to find renames, copies and complete rewrites (very expensive).
$ git diff --find-copies-harder -B -C

# Output diff in reverse.
$ git diff -R

git submodule

As an example, git submodule foreach 'echo $path $(git rev-parse HEAD)' will show the path and currently checked out commit for each submodule http://stackoverflow.com/questions/658885/how-do-you-get-git-to-always-pull-from-a-specific-branch

cd /path/to/repository
echo '' >temp-submodule-info.txt
git submodule foreach --recursive 'echo $path `git rev-parse HEAD`' >>temp-submodule-info.txt
git submodule foreach --recursive 'echo $path `git remote -v`'      >>temp-submodule-info.txt

Git log nice

Git create a patch file

If you want to create a patch file via git diff that can be applied using patch -p0 < patchfile use the following command:

git diff --no-prefix > patchfile

To apply the patch:

patch -p0 < patchfile

If you have an existing git diff patch file that was created without the --no-prefix option, you can apply that patch via:

patch -p1 < patchfile

This will ignore the default a/ b/ source prefixes.

p4merge - visual diff tool (for Ubuntu 18.04)

  • Download: https://www.perforce.com/downloads/visual-merge-tool

  • Save as: /home/marble/Downloads/perforce-com-p4merge-tool/p4v-Linux-x64-2018-3-1719707.tgz

  • Unpack to: /home/marble/bin/p4merge/p4v-2018.3.1719707/bin/p4merge

  • Try alias: alias p4merge='/home/marble/bin/p4merge/p4v-2018.3.1719707/bin/p4merge' — this didn’t work well so far

  • Update ~/.gitconfig:

    [diff]
   tool = p4mergetool
[difftool "p4mergetool"]
   cmd = p4merge $LOCAL $REMOTE
[difftool]
   prompt = false
[merge]
   tool = p4mergetool
[mergetool]
   keepTemporaries = false
   prompt = false
[mergetool "p4mergetool"]
   cmd = /home/marble/bin/p4merge/p4v-2018.3.1719707/bin/p4merge $PWD/$BASE $PWD/$LOCAL  $PWD/$REMOTE $PWD/$MERGED
trustexitcode = false

p4merge - visual diff tool (for Ubuntu 14.04)

Download and install p4merge

Setup p4merge as a visual mergetool

git config --global merge.tool                p4mergetool
git config --global mergetool.p4mergetool.cmd "/Applications/p4merge.app/Contents/Resources/launchp4merge \$PWD/\$BASE \$PWD/\$LOCAL  \$PWD/\$REMOTE \$PWD/\$MERGED"
git config --global mergetool.p4mergetool.trustExitCode false
git config --global mergetool.keepBackup      false

Setup p4merge as a visual diff tool

git config --global diff.tool p4mergetool
git config --global difftool.p4mergetool.cmd "/Applications/p4merge.app/Contents/Resources/launchp4merge \$LOCAL \$REMOTE"

Using p4merge to resolve conflicts

When you run into a conflict when merging simply run:

git mergetool
  1. You will be prompted to run “p4mergetool”, hit enter and the visual merge editor will launch.
  2. Using the merge tool you can resolve the conflict and then save the file.
  3. After you exit the merge tool take a look back at your terminal. You will be asked if the merge was successful, choose yes if all is well or no if you need to start over.
  4. This prompting is happening because the “trustExitCode” option is turned off. Personally I always like to be asked, but you can have git just trust the exit code from the merge tool.

How to keep git log and less output on the screen

From Boris Serebrov:

When git uses less as pager the output of commands like git log disappears from the console screen when you exit from less. This is not convenient in many cases so here is how to fix this.

Just for git commands:

git config --global --replace-all core.pager "less -iXFR"

For less globally (including git) - add to .bashrc or .zshrc and so on:

export LESS=-iXFR

The options we set for less are:

-i ignore case when searching (but respect case if search
term contains uppercase letters)

-X do not clear screen on exit

-F exit if text is less then one screen long

-R was on by default on my system, something related to colors

Solutions

Add global .gitignore file

See https://help.github.com/articles/ignoring-files/

Do:

touch   ~/.gitignore_global
echo "*GENERATED*"     >> ~/.gitignore_global
echo "*NOT_VERSIONED*" >> ~/.gitignore_global
git config --global core.excludesfile ~/.gitignore_global
git config --global -l
cat ~/.gitignore_global

Copy a folder of a repo and keep the history

From: Extract a folder from a git repo into its own repo

  1. Clone the repo:

    git clone oldrepo newrep

  2. Remove every commit except those of the subfolder:

    git filter-branch --prune-empty --subdirectory-filter MYFOLDERNAME master

(untested)

Rebase when pulling

Remember these:

git pull --rebase
git config --global pull.rebase true
git config branch.BRANCH-NAME.rebase true

Remove all merged local branches

git checkout master
git branch --merged | grep -v "\*" | xargs -n 1 git branch -d

(untested)
