Hi there!

I just studied
http://www.kernel.org/pub/software/scm/git/docs/core-tutorial.html
to get more into the details of git. But the following commands:

$ git-cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238
$ git-cat-file "blob" 557db03

just bring up a

fatal: Not a valid object name 557db03de

I guess the documentation is slightly outdated and might need a fix.

Best greets,

Did you actually add a file with the content "Hello World\n"? If not, you 
should not be surprised.

Hth,

Works for me.  The precise names there depend on the files you create
being byte-for-byte identical to the ones created by the echo commands
in the tutorial.  If yours aren't identical, then you should just use
the names that the previous ls command instead.

Argh... yes, I even adopted my numbers to my case, but I just didn't
include the /55/... 2 letter folder name in the /55/7db03de997 object names... :-(

$ ls .git/objects/??/*
.git/objects/55/7db03de997c86a4a028e1ebd3a1ceb225be238
.git/objects/f2/4c74a2e500f5ee1332c86b94199f52b1d1d962
$ git-cat-file -t 7db03de997           <- wrong!
fatal: Not a valid object name 7db03de997
$ git-cat-file -t 557db03de            <- correct!
blob

Jup, those little details... once you don't stick to any tags.
Fine! Thanks! The tutorial, too!

Best greets,
