🔱 Git Commands You Didn't Know

#git #github #bash

TL;DR

One of my favorite things about Git is being as simple as it is and also being customisable and one of those features is aliases. Git supports aliases which means you can give your commands any name you want. I prefer to set aliases for really long commands to avoid searching for them everytime I need it.

The alias config in Git works like this.

git config --global alias.[new_alias] "[previous_git_command]"

# Example
git config --global alias.save commit

From the example above, I won't need git commit again. git save will work good enough.

Add quotes around commands with multiple options.

`git recommit`

git config --global alias.recommit 'commit --amend -m'

git commit --amend allows you to change the last commit message. recommit is simpler and much easier to remmember.

# Change the last commit message with recommit
git recommit "New commit message"

# [master 64175390] New commit message
#  Date: Tue Sep 22 15:09:11 2020 +0000
#  1 file changed, 2 insertions(+)
#  create mode 100644 vue.js

`git commend`

git config --global alias.commend 'commit --amend --no-edit'

Commit amend with --no-edit flag allows you to commit the new changes in repo with the last commit made, so you don't have to repeat the commit messages again.

`git search`

git config --global alias.search 'grep'

# Example
git search [search_term]

git grep allows you to search in the repository for a keyword and it returns the various matches. It is cool, but I don't know what grep means, please tell me if you do. I prefer search instead, easy to remmember and easy to use.

`git here`

git config --global alias.here '!git init && git add . && git commit -m "init 🦄"'

Usually when I initialize a new repo, I'll stage all the files and I'll commit with an initial commit message. git here does it all in one step. Just run it in the folder you want to make a new repo and you are good to go.

`git who`

git config --global alias.who 'blame'

# Example
git who index.ts
# 641753902 (Ephraim Atta-Duncan 2020-09-22 15:09:11 +0000 1)
# 641753902 (Ephraim Atta-Duncan 2020-09-22 15:09:11 +0000 2) console.log("who?")

git blame is used to examine the contents of a file line by line and see when each line was last modified and who the author of the modifications was. If there was a bug, in a line, you find who who did it and blame them.

`git zip`

git config --global alias.zip 'archive --format=tar.gz -o ../repo.tar.gz'

# Example
git zip [branch_name]

The archive commands allows you to create tarballs and zips of your whole repo or some. git zip will make it easy to remmember. Just add the branch name.

`git newbie`

git config --global alias.newbie 'checkout --orphan'

# Example
git newbie [new_branch_name]

git checkout with the --orphan flag allows you to create a branch without any history from the parent branch. No commit, fresh out of the box branch.

`git clonely`

git config --global alias.clonely 'clone --single-branch --branch'

# Example
git clonely [branch_name] [remote_url]

git clonely v3 https://github.com/vuejs/vue-apollo
# Cloning into 'vue-apollo'...
# remote: Enumerating objects: 2841, done.
# remote: Total 2841 (delta 0), reused 0 (delta 0), pack-reused 2841
# Receiving objects: 100% (2841/2841), 1.92 MiB | 330.00 KiB/s, done.
# Resolving deltas: 100% (1743/1743), done.

git clone with --single-branch --branch flags allows you to clone a specific branch from a repo and I can say, I've googled it more than 10 times. Aliasing it is better.

`git plg`

git config --global alias.plg "log --graph --pretty=format:'%C(yellow)%h%Creset -%Cred%d%Creset %s %Cgreen| %cr %C(bold blue)| %an%Creset' --abbrev-commit --date=relative"

# Example
git plg # plg - Pretty Log

There is nothing wrong with git log except that it is a little ugly, no color differences and if you want to customize it, you'll have to do some amount of googling. Fortunately, we have aliasing. Alias the command and you'll get a very pretty log of everything.

`git fresh`

git config --global alias.fresh "filter-branch --prune-empty --subdirectory-filter"

# Example
git fresh [subfolder] [branch_name]
git fresh src main # Don't do this unless you know what you are doing

The series of commands that fresh replace is used to create a new repository out of the contents of a subfolder. filter-branch with it many flags take a the contents of a specified subfolder and replaces the content in the while repo with the content of the subfolder.

TL;DR

Add this to your .gitconfig file.

[alias]
    recommit = commit --amend -m
    commend = commit --amend --no-edit
    here = !git init && git add . && git commit -m \"Initialized a new repository\"
    search = grep
    who = blame
    zip = archive --format=tar.gz -o ../repo.tar.gz
    lonely = clone --single-branch --branch
    plg = log --graph --pretty=format:'%C(yellow)%h%Creset -%Cred%d%Creset %s %Cgreen| %cr %C(bold blue)| %an%Creset' --abbrev-commit --date=relative
    fresh = filter-branch --prune-empty --subdirectory-filter

nice ...thanks for sharing

en.wikipedia.org/wiki/Grep

Read a bit more about standalone grep. It's an important part of any unix system.

Budi Arsana • Sep 27 '20

My only and must have alias git up

alias.up=pull --all --prune

It fetch all branches, delete tracking remote branches that not exist and pull the update.

Ephraim Atta-Duncan • Sep 27 '20

Nice.

Ashiqul • Sep 27 '20

Some names are creative. Nice read. 👍

Ephraim Atta-Duncan • Sep 27 '20

Thanks

Amir Hameed • Sep 26 '20

waow. nice

dsbarnes • Sep 26 '20

I learned of git cherry-pick top of last week, thought I'd toss that one in here too.
Great article!

Spencer Pollock • Sep 25 '20 • Edited

This one is my current favorite. Highly recommended after a git fetch --all to visualize where the branches are at.

[alias]
    tree = log --graph --oneline --all

Ankit Beniwal • Sep 24 '20

Now I will have the proof in order to blame someone for a bug. 😂😂

Cool.

Ephraim Atta-Duncan • Sep 24 '20

😀

Tiago Celestino • Sep 24 '20

Nice!! I’ll update my .gitconfig now!!

Winston Puckett • Sep 24 '20

Oh man. That git here. Where has that been all my life?

Wesley de Groot • Sep 23 '20

My favorite is git recommit.

My aliases:

st = status -s -uno
co = checkout
coffee = "!f(){ if [ `date -j +%a` = 'Fri' ]; then echo 'Friday! Time for beer!'; else echo 'Time for a coffee break. Go get a cup of joe.'; fi };f"
master = checkout master
rmbr = "!f(){ git branch -d \"${1}\"; git push origin --delete \"${1}\"; };f"
mkbr = "!f(){ local args=\"$*\"; local gituser=$(git config user.email); gituser=${gituser%@*}; if [ \"$args\" = \"\" ]; then args=\"$(date \"+%Y-%b-%d\")\"; fi; args=${gituser:-${USER}}/$args; args=$(echo \"$args\" | tr ' [A-Z]' '_[a-z]'); git checkout -b \"$args\"; };f"
ls = "!f(){ if [ -z \"${1}\" ]; then echo 'git ls [HASH] • show the files involved in the commit'; else git diff --name-only \"${1}^..${1}\"; fi; };f"
at = rev-parse --abbrev-ref HEAD
unstage = restore --staged
unadd = restore --staged
discard = checkout --
alias = config --get-regexp ^alias\\.
d = difftool
ds = difftool --staged
branches = branch --all

git ls hash
— is useful to show the files involved in a commit.

Ephraim Atta-Duncan • Sep 23 '20

I must say, they are pretty awesome.

Catriel Lopez • Sep 23 '20

Grep stands for "Global Regular Expression Printer". It gives you a clue about how it works, which is important, but "git search" doesn't.

I really like the plg and zip aliases, so I'm definitively stealing those! Thanks for writing!

Cliff • Sep 26 '20 • Edited

That's more of a backronym, really. It actually comes from the relatively ancient ed line editor's command g/re/p which basically means "global search / for a regular expression / print matching lines". So it's at least a fairly accurate backronym to the source.

The g command still sort of lives on in vi/Vim's ex mode commands. The most common use these days is probably for g/pattern/d, which does a global search for the pattern and deletes matching lines, sort of the opposite of the original g/re/p command.
