Hi.

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

Hi.

What is "non-depressing"?

Try this if you are using bash:

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

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

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

Hi,

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

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?

Ciao,
Dscho

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,
