Possible to read file from git cache?

I can see list of files using below command

Use git cat-file or git show. For example

for f in `git ls-files --cache`; do
    echo -- "----- File (cat): $f -----"
    git cat-file -p HEAD:$f
    echo -- "----- File (show): $f -----"
    git show HEAD:$f
    echo -- "----- End of File: $f -----"
done

Correct me if I'm wrong. If I run a command like `git show HEAD:yarn.lock`, then from where will it pick the content from? From `HEAD`? Or from `git cache`? – Isaac Jul 13 '19 at 01:17

From the `HEAD`. Do you want index? (It's now called index, not cache). Just use `:$file`. – phd Jul 13 '19 at 01:42

You could use checkout-index. This command copies a file from the git cache (index) into the worktree.

Normally it overrides the working copy, but with the parameter --temp you could create a copy of your file.

git checkout-index --temp -- myfile.ext
