Renaming files with Git

Renaming files can be a bit of a pain as git, by default, is not case sensitive. So if you rename a file you need to run the following command to ensure any case-sensitive changes are picked up

git mv -f test/postman/Pagro-Home-API.postman_collection.json test/postman/pagro-home-api.postman.collection.json

Git aliases

Git has an alias command built in that is cross platform. https://www.git-scm.com/book/en/v2/Git-Basics-Git-Aliases

Git bisect

git bisect is a pretty powerful tool. Say you know there was a bug introduced between 2 commits, you can give it the known good commit and the known bad commit and step through the commits one at a time, running each one against a test script. For example, a jest suite. It is very useful if you don’t know when a bug was introduced and need to identify the commit.

Anecdote about how much time bisect could save you

At my old job, we were building mainline Linux kernels for specific pieces of hardware we supported. There was a bug in the linux kernels intel graphics stack that would occasionally prevent our hardware from booting.
I setup a test script that would run during a bisect, that would build to the device over SSH and reboot it N number of times. If the script was unable to establish an ssh connection within N seconds after a reboot, I had it throw an error.
Using that method I was able to let git bisect run automatically and eventually we found the commit in the linux kernel that broke our hardware and were able to report the bug.

Git describe

Git describe takes the form of:

git describe <ref>

Where <ref> is anything git can resolve into a commit. If you don’t specify a ref, git just uses where you’re checked out right now (HEAD).

The output of the command looks like:

<tag>_<numCommits>_g<hash>

Where tag is the closest ancestor tag in history, numCommits is how many commits away that tag is, and <hash> is the hash of the commit being described.

Look into this some more. Will these be useful in my day to day workflow?
