How to I add something to the .gitignore so that the match is not recursive?

For example, I wish to ignore the directory foo and the file bar.txt in the current directory, but not any that exist in subdirectories.

I have tried this for my .gitignore file:

foo/
bar.txt

But unfortunately git applies this recursively, so that otherdir/bar.txt and otherdir/foo/ also get ignored, which is not what I want.

(Is there a command in git that shows me all ignored files, and reference the .gitignore file that is responsible for the file being ignored? This would be useful for debugging.)

回答1:

The solution is to place a leading slash on the .gitignore entries:

/foo/
/bar.txt

(I thought I tried this before posting on StackOverflow, but clearly I hadn't tried it properly, as this works perfectly.)

From the gitignore manpage:

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

So !* as the first line in your .gitignore will clear all previous patterns.
