Hi.

Is there a (non-depressing) way of getting "which files did not change 
since <rev>" out of git?

Rene.

What is "non-depressing"?

Try this if you are using bash:

  comm -13 <(git diff --name-only your-rev-here) <(git ls-files)

-- Hannes

```

That classifies as non-depressing, thank you. --name-only, process 
substitution _and_ comm -13 hadn't featured in my attempts yet.

Hi,

Thanks.  I learnt two new things from that: comm (funnily, I did not know 
that tool), and <() (looks almost like a puffin, doesn't it?).

But should it not be -12?

I don't think so:

  -1 .. suppress lines unique to 1st arg, i.e. removed files
  -2 .. suppress lines unique to 2nd arg, i.e. unmodified files
  -3 .. suppress lines in both, i.e. modified and added files

We want to keep lines that -2 would remove, that leaves -1 and -3.

Oh, but of course!

Thanks again,

Neat, I never knew about comm before. I probably would have come up  
with something like

   cat <(git ls-tree -r $REV) <(git ls-tree -r HEAD) | sort | uniq -d  
| cut -f 2 | sort
