Git - File (Blob)
About
File management in Git (blob and not directory)
Note that a file for git is an blob object that may be:
- on the local file system
- or not (ie in the git file system database)
Management
Status
See Git - File Status and short status
Identifier
A file (or blob) identifier is the hash of its content.
Show
To see the content, with the show command and its hash
git show thehash
Commit History for one File
git log --all --full-history -- **/thefile.*
What is the Git Log (also known as commit history or commit log) ?
List
git-ls-files 1) - Show information about files in the index and the working tree
Show a file for a commit
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>
- 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
