Hi, hopefully a very simple newb question: "what is the command to
report the current SHA1?" - explanation below.

I'm vc-ing my MSc thesis and associated code with git, it's working
great for me. My supervisor requires regular submissions as editable
Word docs so I publish my source HTML to him as RTF. He adds comments
via Word & returns to me, I read in Open Office 3. This works, but
there is often a week or more between him receiving the doc and
returning it to me with comments.

I'd like to put the current SHA1 as text in the RTF so that I can
generate a diff from my current version before responding to his
comments.

The question then is: what is the command to report the current SHA1?
Note I never branch in the HTML repo, it's entirely linear.

Many thanks, al.

```

If the "current SHA1" means "the SHA1 of the most recent commit in the
current branch" then usually

    git show

is the simplest way. There are many ways to print _only_ the SHA1.
Examples:

    git log -1 --pretty=format:%H
    git rev-list -1 HEAD

```

For listing a single commit, I usually think of show and rev-parse
before using commands that list multiple commits. (Of course, having
to use --quiet doesn't make show any shorter than log -1.)

    git rev-parse HEAD
    git show --quiet --pretty=format:%H

Instead of doing that, you can put a tag on the version you deliver.
