如何忽略Git中的目录级别，而不忽略以相同名称开头的其他目录？

Question

How to ignore top level cache but not 'apps/cache'?

I have such structure.

cache
apps/cache
conf/cache

I want to write rules to ignore only top level cache .

cache - IGNORE
apps/cache - NOT IGNORE
conf/cache - NOT IGNORE

How to do in git?

Answer 1

Just prefix the directory to be ignored with /. This will ignore the mentioned files/directories only in the directory where .gitignore is present.

eg: /cache

Answer 2

Just provide the full path to your cache directory:

/cache

This way, things like app/cache and conf/cache won't be included.

Answer 3

Note: the ability to anchor the path to the current folder of a git repo comes from commit d0bfd02 (April 2007, git 1.5.2-rc0) :

Add basic infrastructure to assign attributes to paths

This adds the basic infrastructure to assign attributes to paths, in a way similar to what the exclusion mechanism does based on $GIT_DIR/info/exclude and .gitignore files.

Each line in these files defines a pattern matching rule.

The first token on the line is a shell glob pattern.

For glob matching, the same "if the pattern does not have a slash in it, the basename of the path is matched with fnmatch(3) against the pattern, otherwise, the path is matched with the pattern with FNM_PATHNAME" rule as the exclusion mechanism is used.

That is why the documentation soon included (June 2007, git 1.5.2.1):

A leading slash matches the beginning of the pathname;
for example, " /*.c " matches " cat-file.c " but not " mozilla-sha1/sha1.c "
