For simplicity, I'll assume with "known to git" you mean whether the
current branch's tip has some content at the given path. Then you could write:
if git rev-parse HEAD:"$p" >/dev/null 2>&1
then
# git knows about $p
else
# git does not know about $p

Yes, thank you, Johannes and Shawn, this works.
(A bit slow, though: with this test enabled my script takes 77 secs;
without it it takes 0.3 secs. The time is spent in 9000 calls to the
above test (the rev-parse version). (ok, the fact that there is a Perl
system call around it might take some time, too).)
[For the record:
Shawn's ls-files variant takes: 148 secs
Shawn's cat-file variant takes: 251 secs
Time taken by time; roughly half user, half system.
]
As this script won't run often, that not too big a deal.
Still I would have hoped for a quicker way.
Thanks
