How do I list all the files in a commit?

How can I print a plain list of all files that were part of a given commit?

Although the following lists the files, it also includes unwanted diff information for each:

git show a303aa90779efdd2f6b9d90693e2cbbbe4613c1d

Solution

Preferred Way (because it's a plumbing command; meant to be programmatic):

$ git diff-tree --no-commit-id --name-only bd61ad98 -r
index.html
javascript/application.js
javascript/ie6.js

Another Way (less preferred for scripts, because it's a porcelain command; meant to be user-facing)

$ git show --pretty="" --name-only bd61ad98    
index.html
javascript/application.js
javascript/ie6.js

The --no-commit-id suppresses the commit ID output.
The --pretty argument specifies an empty format string to avoid the cruft at the beginning.
The --name-only argument shows only the file names that were affected (Thanks Hank). Use --name-status instead, if you want to see what happened to each file (Deleted, Modified, Added)
The -r argument is to recurse into sub-trees
