These are some low-level tips for the console, for power users of Git.
Useful config 🔗
branch.autosetuprebase=always(documentation): I find it easier to work with Git this way
core.editor=emacs -nw(documentation): that's the editor that will be invoked every time Git needs to ask you about a commit message, when you're squashing commits, etc (and of course, you want emacs for that)
gpg.program=gpg2(documentation): you will need to set up these variables (and possibly a couple other) if you want to sign your commits to GitHub using GPG (recommended)
Safest way to “update” a local copy 🔗
I find this sequence of commands the “safest” way to quickly “refresh” a clone of some remote repo, and at the same time check its status (where “safest” means “reducing to the minimum the probability of messing up things with conflicts, outdated branches, uncommitted changes, etc”):
$ git branch -a $ git pull -r $ git status $ git remote prune origin --dry
$ git branch -adisplays information about all branches, both local and remote
$ git pull -rfetches changes from the remote and “rebases the current branch on top of the upstream branch after fetching”
$ git statusshows you the status of your copy: whether there are new files, missing files, unstaged changes, or commits pending push
$ git remote prune origin --drytells you if any branch in the remote has been recently removed. (Submit the same command without the
--drypart to actually remove those remotes from your local
origin. That will still not remove local branches automatically, but you can do that yourself with
git branch -d <BRANCH>if you see some branch is no longer necessary.)
You can have those four lines as an alias, or inside a script somewhere.
Even better: if you set up the aliases suggested above, the whole thing becomes:
$ git br -a;git pl -r;git st;git re prune origin --dry
You can then type it and run it just once, and, from that moment on, simply recover the line from your shell history.
For example, if you're using Bash: press
r, then start typing a distinctive chunk of the line
st;gi); if you used it not too long ago for the last time, the entire line should appear, and you can
An alias to view the history of the repo 🔗
alias.lg=log --graph --abbrev-commit --decorate --date=relative \ --format=format:'%C(bold blue)%h%C(reset) \ - %C(bold green)(%ar)%C(reset) %C(white)%s%C(reset) \ %C(dim white)- %an%C(reset)%C(bold yellow)%d%C(reset)' --all
Then, simply type
$ git lg
for a colourful graph of commits, tags and branches.
