git show <commit-sha>

Push master branch to origin

git push origin master

List all branches

git branch -a

List remote branches

git branch -r

Sync list of remote branches

git remote update

Checkout remote branch into local repository

git checkout -t -b <local-name> <remote-name>

Create a branch

git checkout -b <name>

Push local branch to remote

git push origin <remote-name>

Merge two branches

git checkout <target>
git merge <source>

Merge two branches with squash

git checkout <target>
git merge --squash <source>

See what branches are merged into master

git branch -r --merged master

Ignore files globally

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

pull changes from the server + rebase (equivalent of git stash save && git pull && git stash pop && git push) + push

git pull --rebase && git push

Set up git inet server

git daemon --base-path /home/git --verbose

Add remote origin

git remote add origin <url>

Fix 'branch not tracking anything'

git config --add branch.master.remote origin
git config --add branch.master.merge refs/heads/master

Extract patch from a given file

git diff --patch-with-raw rev1 rev2 patched_file > diff_file

Diff with paging

GIT_PAGER='less -r' git dc

Apply a patch

git apply diff_file

Publish branch

git push origin <name>

Delete remote branch

git push origin :<name>

Cherry-pick a commit

git cherry-pick -n <sha>

Revert commit

git revert -n <sha>

Reset HEAD to n commits back

git reset --hard HEAD~<n>

Squash N last commits

git rebase --interactive --autosquash HEAD~N

search git log commits

git log -S “free text”

remove file from history (can use 'git rm -rf…' to remove files recursively)

git filter-branch --index-filter 'git rm --cached --ignore-unmatch <path to file>' --prune-empty --tag-name-filter cat -- --all
git push origin master --force
rm -rf .git/refs/original/
git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now

Prune history

git gc
git gc --aggressive
