Identifier

A file (or blob) identifier is the hash of its content.

Git - Log (Commit History)

List

git-ls-files 1) - Show information about files in the index and the working tree

Show a file for a commit

show

git show commitHash:path/to/file

Restore it

The caret symbol (^) gets the checkout prior to the one identified

git checkout <SHA>^ -- <path-to-file>

Git - Checkout

  • Update the requested file from the given branch (here the remote branch origin/master).
git checkout remote/branch fileName
# Example
git checkout origin/master fileName

Rename or move a file

git mv <options>…​ <args>…​
#
git mv oldName.ext newName.ext

This is not rename tracking.

Its just an utility class that remove a file and add another one with the same content because Git don't track rename

Remove it

  • from the repository (index) but not from the file system
git rm --cached myFileName.extension

more Git - rm (Remove)

History

With log, you can see the commit history and the hash.

The –follow will list the history of a file beyond renames (it searches for similar content using heuristics).

Example for one file:

git log --follow --oneline -- MyFile
# or for full sha1
git log --follow --pretty=oneline -- MyFile
