Using bash history expansion, how do I rerun the last command with a different last word?

NOTE: I plan on answering my own question.

This is the last command I ran on the command line:

git co head -- a/path/to/a/file.ts

I want to run this a few more times but with different file paths for the last argument/parameter. This page explains history expansion, and I think the answer I’m looking for is in this subsection, but it lacks examples.

Using history expansion, how would I rerun the previous command with a different file path? For example, how would I run:

git co head -- a/path/to/another/different-file.ts

This is probably a duplicate but I haven’t been able to find the answer I’m looking for. These posts look like they might have the answer but they didn’t:

• Rerunning the same command with a different parameter
• Replace the last word of last command but keep the first
