In your case, you'd want something like (within the t/perf directory): $ ./run HEAD . p7519-*.sh where this patch is the uncommitted state (alternatively you could compare the two revisions directly in the case that you have already committed). > diff --git a/t/perf/p7519-fsmonitor.sh b/t/perf/p7519-fsmonitor.sh > index def7ecdbc7..9313d4a51d 100755 > --- a/t/perf/p7519-fsmonitor.sh > +++ b/t/perf/p7519-fsmonitor.sh > @@ -114,7 +114,8 @@ test_expect_success "setup for fsmonitor" ' > fi && > > git config core.fsmonitor "$INTEGRATION_SCRIPT" && > - git update-index --fsmonitor > + git update-index --fsmonitor && > + git status # Warm caches Seems reasonable, and the comment is much appreciated :-).
