Useful Git Commands

By David Walsh on February 15, 2012

I've used git quite a bit but I don't consider myself a git expert, per se. I often find myself looking up the same basic commands so I thought I'd share them there so I'd have a fast reference, and maybe this will help you out too!

Create and Checkout a New Branch

#branches from currently checked out directory
git checkout -b <branchName>

Checkout a Remote Branch

git checkout -b <localBranchName> origin/<remoteBranchName>

Abort Changes of a File

git checkout -- <fileName>

Modify the Previous Commit's Message

git commit --amend

Partial Change Checkin

git add --edit

Undo the Previous Commit

git revert HEAD^

Temporarily Stash Changes, Restore Later

# After changes have been made...
git stash

# Do some other stuff here, like switch branches, merge other changes, etc.

#Re-apply the changes
git stash pop

Delete a Remote Branch

git push origin :<branchName>

Pull in the Latest from a Shared Repository

# Add a remote branch
git remote add <remoteName> <gitAddress>
	# For example:  git remote add lightfaceOfficial git://github.com/darkwing/LightFace.git

# Get changes from that branch
git fetch <remoteName>

Tagging, Deleting, and Pushing Tags

# Create a Tag
git tag <tagName>

# Delete the tag
git tag -d <tagName>

# Push Tags
git push --tags

Who F'd it All Up?

git blame <fileName>

These basic git commands should help you on your way. Have a tip you'd like to share with others? Please share!

CSS vs. JS Animation: Which is Faster?
How is it possible that JavaScript-based animation has secretly always been as fast — or faster — than CSS transitions? And, how is it possible that Adobe and Google consistently release media-rich mobile sites that rival the performance of native apps? This article serves as a point-by-point...

CSS Gradients
With CSS border-radius, I showed you how CSS can bridge the gap between design and development by adding rounded corners to elements. CSS gradients are another step in that direction. Now that CSS gradients are supported in Internet Explorer 8+, Firefox, Safari, and Chrome...

pointer Media Query
As more devices emerge and differences in device interaction are implemented, the more important good CSS code will become. In order to write good CSS, we need some indicator about device capabilities. We've used CSS media queries thus far, with checks for max-width and pixel ratios.

Full Width Textareas
Working with textarea widths can be painful if you want the textarea to span 100% width. Why painful? Because if the textarea's containing element has padding, your "width:100%" textarea will likely stretch outside of the parent container -- a frustrating prospect to say the least. Luckily...

Fetch from all remote repositories:
git remote update

See a nice ascii graph of your branches:
git log --oneline --graph --all

+1 on the ascii graph. I even make an alias for it.

git config --global alias.timeline "log --oneline --graph --decorate"

So all when i need my ascii graph I just:
git timeline

sanija

git remote update-git log --oneline --graph --all="git config --global alias.timeline "log --oneline --graph --decorate"{git timeline}

Hey, just to expand on “undo previous commit”:

git reset --hard HEAD~3

This will revert three commits back.

Not sure why this works for you, but I really have to do this to stash:

$ git stash save “The name of the stash”

And then to put it back

$ git stash apply

Or

$ git stash apply “The name of the stash”

The below cmd is used for search:

grep log –grep=”your search word”

The ASCII timeline (above) can be customised further, to good effect, by using the –format option, e.g. to add time information about the commits (helpful in a timeline!):

git log –graph –all –format=’%h %an %ad – %s’

(or use %ar instead of %ad if you like relative dates)

Mix with other options to suit. Full details of the format option are in the git-log man page (quite far down the page).
