# Ignore all
*

# Unignore all with extensions
!*.*

# Unignore all dirs
!*/

### Above combination will ignore all files without extension ###

# Ignore files with extension `.class` & `.sm`
*.class
*.sm

# Ignore `bin` dir
bin/
# or
*/bin/*

# Unignore all `.jar` in `bin` dir
!*/bin/*.jar

# Ignore all `library.jar` in `bin` dir
*/bin/library.jar

# Ignore a file with extension
relative/path/to/dir/filename.extension

# Ignore a file without extension
relative/path/to/dir/anotherfile

我在GOPATH目录中创建了一个包含两个条目的.gitignore文件。

/bin
/pkg

目前，它忽略所有已编译的开发。

在某些子目录中也可以忽略，而不仅仅是在根目录中:

# Ignore everything in a root
/*
# But not files with extension located in a root
!/*.*
# And not my subdir (by name)
!/subdir/
# Ignore everything inside my subdir on any level below
/subdir/**/*
# A bit of magic, removing last slash or changing combination with previous line
# fails everything. Though very possibly it just says not to ignore sub-sub-dirs.
!/subdir/**/
# ...Also excluding (grand-)children files having extension on any level
# below subdir
!/subdir/**/*.*

或者，如果你只想包含一些特定类型的文件:

/*
!/*.c
!/*.h
!/subdir/
/subdir/**/*
!/subdir/**/
!/subdir/**/*.c
!/subdir/**/*.h

如果你想的话，它甚至可以像每个新子目录一样工作!：

/*
!/*.c
!/*.h
!/*/
/*/**/*
!/*/**/
!/*/**/*.c
!/*/**/*.h

前导斜杠只在前两行中重要，在其他行中是可选的。在!/*/和!/subdir/中的尾斜杠也是可选的，但仅在这一行中。

.gitignore使用glob编程来过滤文件，至少在Linux上是这样。

我准备在一个Meetup上做一个编码演讲，在准备过程中，我创建了一个包含几个子目录的目录，这些子目录根据我想要呈现它们的顺序命名:01_subject1, 02_subject2, 03_subject3。每个子目录都包含一个源文件，其扩展名与语言相关，可编译为一个可执行文件，根据惯例，该文件的名称与不带扩展名的源文件名匹配。

我排除了以下.gitignore行以数字为前缀的目录中的编译文件:

[0-9] [0-9] / [! \] * _ *

According to my understanding of the documentation, it shouldn't work. Having the trailing asterisk should fail because it should match any number of unspecified characters, including the '.' + extension. Omitting the trailing asterisk should fail (and does) because [!\.] matches only a single non-period character. However, I added the trailing asterisk, as I would for a regular expression, and it works. By work, I mean that git notices changes to the source file, but not the existence or changes to the compiled files.

你可以试试你的。gitignore:

*
!*.c

这种方法有很多缺点，但对于小型项目是可以接受的。

只需添加hello或/hello到你的.gitignore。要么工作。
