Can I reference a script in 'git diff path/to/file' using it's index instead of it's path?

I do often want to quickly check on the changes I made. Using git status often looks like this:

$ git status
On branch develop
Your branch is ahead of 'develop' by 2 commits.
  (use "git push" to publish your local commits)

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   Assets/_Project/Scripts/Controls/ControllerManager.cs
        modified:   Assets/_Project/Scripts/UI/TabletManager.cs

no changes added to commit (use "git add" and/or "git commit -a")

To check on the changes I made I would have to use git diff Assets/_Project/Scripts/UI/TabletManager.cs with the full path to the file which are often quile long. But since I use this feature quite often with just a few changed script I wonder whether there is something like a quick access option? Maybe by passing the index of the modified file? Something like git diff 1 to see the changes made in TabletManager instead of the full path.

Solution

I do not think git has the quick access option you wish, since most of the times the autocompletion is enough, as @torek told you in the comments.

If you really want this feature, you can create it yourself.

First create a folder dedicated to git extensions and cd to it

Create a script file and name it something like git-easydiff. Now I am adding it as a local alias but you can even extend git with custom commands, here described how. By the way, a possible script could be:

#!/bin/bash
changed_files=( $(git diff --name-only) )
for ((i = 0; i < ${#changed_files[@]}; i++))
do
    echo "$i - ${changed_files[$i]}"
done;

read -p "Index of file to git-diff: "

git diff ${changed_files[$REPLY]}

And now the alias
```
git config alias.easydiff '!/directory_with_git_extensions/git-easydiff'
```
the ! at the beginning is necessary because the command is not a git command.

You can call it as git easydiff, the output is:

0 - file1
1 - file2
Index of file to git-diff: 1
... diff for file2 ...
