git cheat sheet

For a while now, I’ve had a gradually-expanding note with various git commands that I’ve been using as a cheat sheet for git tasks that I do not do often, but regularly enough to write them down.

I figure putting them here will not only make them (slightly) easier to get to every time, but may also help other folks out.

So here they are! Keep in mind that this is just a quick (and intentionally incomplete) cheat sheet – if you are learning git for the first time, you’re better off looking elsewhere (this is a good place to start).


Delete a file from the repo (opposite of ‘git add’):

git rm filename

revert a file to the current committed version

git checkout -- filename

cache credentials when using https (seconds):

git config credential.helper 'cache --timeout=300'

clear cached credentials:

git credential-cache exit

ignore changes to a versioned file:

git update-index --assume-unchanged <file>

stop ignoring those changes:

git update-index --no-assume-unchanged <file>

change commit message of last commit:

git commit --amend -m "New commit message"


pull a new branch from origin and track it

git checkout --track -b origin/daves_branch

push a new local branch to origin:

git push -u origin branch-name

create a new branch:

git checkout -b new_branch

merge changes from branch hotfix into master:

git checkout master
git merge hotfix

delete the local branch:

git branch -d hotfix

track a remote branch:

git branch --set-upstream krystof_plots origin/krystof_plots


create a tag and push it to origin:

git tag -a v1.4 -m 'my version 1.4'
git push origin --tags

pull tags:

git pull --tags

find out what tag you’re on:

git describe --tags


Add upstream remote:

git remote add upstream

sync a fork (

git fetch upstream
git checkout master
git merge upstream/master

Reset a fork to whatever is on upstream:

git fetch upstream
git checkout master
git reset --hard upstream/master
git push origin master --force


Add a git repo as a submodule:

git submodule add

To make the submodule track a the master branch:
open .gitmodules, and add a line to the submodule info:

branch = master

Catalina 2016

I made it out to Catalina once again for a camping trip; here are a few photos.

Bryce Canyon

Bryce Canyon National Park is like walking on another world. Really, though, it is beyond the power of words or photos to do a place justice, so do yourself a favor and go visit it.

You may enjoy these photos as a teaser.

Vermilion Cliffs

The Vermilion Cliffs are the second step up in the Grand Staircase of the Colorado Plateau, and yet another part of the spectacular landscape of southern Utah.

When hiking in, eventually you reach a point where there are no more trails – you need to find your own way through the rock formations and canyons. That makes hiking there all the more enjoyable – it rekindles a sense of adventure and discovery.

Here are some photos.

Coral Pink Sand Dunes

Coral Pink Sand Dunes State Park is a State Park in Southwestern Utah. I found it a very unique place – a valley filled with sand, but on either side there is vegetation, even trees. The color of the sands is very striking; the photos can’t quite do it justice.


I was up in Utah for a weekend recently, in the general vicinity of Salt Lake City. Here are some photos.

Montaña de Oro

Montaña de Oro State Park is on the Pacific coast, not far from Morro Bay. I made it up there for a weekend recently – here are some photos.

Up from Islip Saddle

Once again, I hiked up in the vicinity of Islip Saddle, and, once again, here are some photos. Hope you like ’em.

Zion National Park – The Narrows

To complete my Zion trilogy, here are some photos from The Narrows, probably the most popular hike in the park. It is popular for good reason – it is fantastic. On the flip side, of course, it gets crowded, particularly near the beginning. You can see that in the last photo.

Zion National Park – Angels Landing

Angels Landing – strenuous climb, narrow route with cliff exposures, hazardous during thunderstorms, darkness, and ice/snow conditions. So warns the sign at Scout Lookout, approximately halfway up to the top. Angels Landing is a landmark in Zion Canyon, and one of the most spectacular hikes I’ve been on.

As usual, here are some photos.
