如何用gitignore忽略子目录文件？

Question

我想忽略git系统中除* .c文件之外的任何文件。我写了.gitignore这样的文件。

!**/*.c

虽然我的文件没有被忽略。

Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)

modified:   .gitignore

我该怎么办？
我只想存档* .c源文件。

Answer 1

我想忽略除* .c

之外的所有文件

将其写在2个单独的行上

# ignore all files 
*

# do not ignore any .c files
!*.c

# you also don't want to ignore your .gitignore file so you have to add it as well
!*.gitignore
