I'm trying to collect all operations related to index from user
perspective and corresponding commands. The list may be put to git
wiki if people think it can help newbies:

update file content to index: git update-index file

Or "git add file" woth new git.

add a file to index: git add file
delete a file from index: git update-index --remove --force-remove
(or remove that file in workdir and do git update-index --remove)

Or "git rm file" (old version did remove only from index, new version
is to remove also from working directory if it matches HEAD)

read a tree to index: git read-tree treeish, git reset treeish
read a file from a tree to index: git ls-tree <tree-ish> file|git
update-index --index-info --stdin
copy a file from index to workdir: git checkout-index file

Or just "git checkout -- file"

refresh index: git update-index --refresh
copy entire index to workdir: git checkout-index

Or just "git checkout"

output a file from index to stdout: ?? (is there a command for this?)

"git cat-file -p ::<filename>"

list files in index: git ls-files
compare index and workdir file listing: 
   git ls-files (with lots of options here) 
diff between workdir and index: git diff
diff between index and a tree: git diff --cached <tree-ish>

diff between workdir and tree: git diff <tree-ish>
