How to find out in which tag a file change is included

Question

I want to find out which files changed in what tag. So I use git whatchanged but this prints me the commit IDs. I want to print the commits in a format like in git describe (which takes the last tag and adds the number of additional commits.

The commands

git whatchanged --pretty=%d *
git whatchanged --pretty=%gd *

are both not working (no output of the commit info at all).

EDIT:

I am using the command on a list of files (by using the *), i.e. what happens if the tagging took place after that commit. Aim is to find out the software version which contains the commit

Based on VonC's answer I ended up in using

FILEPATH=/the/path/I/want/to/Observe
git log --name-only --oneline --tags --pretty="%d"|egrep "$FILEPATH|^ \("

Explanation:

git log shows the changes of the full repository including the tags. Then I grep for the files I am interested in. Additionally I grep for ␣( at the beginning of a line to get the tag names which look for example like ␣(1.1.0)

Great, that seems more precise than my answer. +1 – VonC Jul 23 '14 at 08:13

You are not supposed to use whatchanged from quite some time now: see "Difference between git-log and git-whatchanged?".

Instead, use git log:

git log -p --no-walk --tags --pretty="%H %d" --decorate=full

That works correctly since git 1.8.5.4 (see "show all tags in git log")

With the -p option, it display the diffs.

Other options are available for displaying files:

 git log --name-only --oneline --tags --pretty="%d" | grep -v "^$" | more

(See more at "How to show changed file name only with git log?")

For instance, on the git repo itself:

C:\Users\VonC\prog\git\git>
git log --name-only --oneline --tags --pretty="%d"|grep -v "^$"|more

This shows the diffs - what about only the changed filenames? — Alex, Jul 23 '14 at 07:32
I also edited the question - that might make it more complicated. — Alex, Jul 23 '14 at 07:33
