进入工程目录

gaoliwendeMacBook-Pro:LeetCode-go gaoliwen$ pwd
/Users/gaoliwen/go/src/github.com/glw0223/LeetCode-go
gaoliwendeMacBook-Pro:LeetCode-go gaoliwen$ ls -lhat

.idea是想要忽略的文件夹

建立gitignore文件

在.git的同级目录建立文件.gitignore（注意前面有个点，这是隐藏文件），并添加忽略.idea文件夹

gaoliwendeMacBook-Pro:LeetCode-go gaoliwen$ vim .gitignore
gaoliwendeMacBook-Pro:LeetCode-go gaoliwen$ cat .gitignore 
.gitignore
.idea

验证效果

当然也可以把.gitignore文件提交，方便协同开发
