From 74b46e32cb3907a4a062a0f11de5773054b7c71a Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 12 Apr 2005 00:23:14 -0700 Subject: Add a "check-files" command, which is useful for scripting patches. In particular, it verifies that all the listed files are up-to-date in the cache (or don't exist and are ready to be added). --- check-files.c | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 check-files.c (limited to 'check-files.c') diff --git a/check-files.c b/check-files.c new file mode 100644 index 000000000..c74bf87d2 --- /dev/null +++ b/check-files.c @@ -0,0 +1,47 @@ +/* + * check-files.c + * + * Check that a set of files are up-to-date in the filesystem or + * do not exist.
