I need a plumbing command to print the commit message of one given commit - nothing more, nothing less.

If you have the hash for a commit, you can use the git show command to display the changes for that single commit. The output is identical to each individual commit when using git log -p .
`git log` command is used to view the commit history and display the necessary information of the git repository. This command displays the latest git commits information in chronological order, and the last commit will be displayed first.
The most basic and powerful tool to do this is the git log command. By default, with no arguments, git log lists the commits made in that repository in reverse chronological order; that is, the most recent commits show up first.
It's not "plumbing", but it'll do exactly what you want:
$ git log --format=%B -n 1 <commit> If you absolutely need a "plumbing" command (not sure why that's a requirement), you can use rev-list:
$ git rev-list --format=%B --max-count=1 <commit> Although rev-list will also print out the commit sha (on the first line) in addition to the commit message.
