Git Cookbook

Overview

Git cheatsheet.

Staging files

Stage a file or files

$ git add [path]

Stage all files

What this won't do is stage deletes.

$ git add ./

To stage everything including deleted files:

$ git add -A

Unstaging and reverting

Unstage a file or files

This will unstage the file, but edits that have been made to the file will remain unchanged.

$ git reset [path]

Note: git reset as described above will throw this error prior to the initial commit:

fatal: Failed to resolve 'HEAD' as a valid ref.

If files have been staged prior to the initial commit, then

$ git rm --cached [path]

Reverting file edits

$ git checkout HEAD [path]

Syncing a repo with subsequent changes to the master

Scenario: Create a branch, make edits. In the meantime other work is being done by other members of the team. The time comics to push your changes out. The goal is to merge their changes into yours locally then push it all out.

• See what files have been touched:

$ git status -s

• View (unstaged) edits for a specific file:

$ git diff -- [path]

• Switch from the local branch to 'master'.

$ git co master

• Merge the updated local 'master' with the local branch, resolving any conflicts:

$ git branch
* master
  mybranch
$ git co mybranch
$ git merge master

Commmiting changes

$ git co myBranch
$ git status -s
  # add any files that need to be added to the commit
$ git commit -m 'commit message'
  # the "commit message" is required
$ git push origin myBranch

See the Mediabistro wiki for instructions on how to put the changes on 'preview'.

Reports and diffs

• View all branches and commit messages:

$ git log --oneline

• View commit messages for a single branch:

$ git log --oneline [branchname]

• View the files touched between two commits

$ git diff --name-only SHA1 SHA2

Where you include just enough of SHA1 and SHA2 to identify the commits (usually about 4 characters).
