git clone --depth 20 server:git/repo will not get the whole tree, but just the info and files for the last 20 commits git log # will show the last 20 commits ls dir cat dir/file

exactly -- I need some intrinsic knowledge of how many commits I need to fetch and then fetch all files touched by those, but the point is that I do not know how many commits, and I do not want to fetch anything irrelevant. I just need to
1. see what files are there NOW (after all GIT is a content tracking, right? ;-) )
svn (and probably bzr, according to the blog -- I never used those features myself) provide such functionality. I did need it a few times too. That is why was my comment

You are right, but I usually set up gitweb for those needs.

I thought that git does not have files, only changes?

The other way around. Basically, Git stores complete objects rather than some delta thing. Creating some commit whose diff reads
diff --git a/net/ipv4/netfilter/ipt_ECN.c b/net/ipv4/netfilter/ipt_ECN.c
will get you a .git/objects/55/0811365ac655c3b2d4f9183112e15ad0ae17ba. It is compressed, but it is still standalone/complete/non-deltified. You can nuke all other objects, and git show 550811365 should still succeed.
Deltified packs are a strap-on option (one that's enabled by default because of its usefulness) to the base design.

umm, One of us is misunderstanding something
doing a
git clone --depth 20 server:git/repo
doesn't give you only the files that have changed in the last 20 commits, it gives you ALL the files in the project, as they existed (changed or not) for the last 20 commits
so if you only care about what the files are NOW you can do "--depth 1", no need to know when it changed.
If you want the last 20 changes of a file, and that file hasn't changed for the last 1000 commits, then you really do want the full history, because the file may not have changed 20 times since it was created
