git忽略某些子目录/文件夹及其内容

Question

I have the following directory structure:

ls -l experiment/

foo.sh
gen__20190425_144843
gen__20190425_144854
bar.yml

in which gen___ are folders.

How do i write the .gitignore file to:

• keep track of foo.sh and bar.yml
• and not keep track of all the gen___ folders

I've tried this but does not work (still tracks the gen folders)

./experiment/gen__*/*
!./experiment/foo.sh
!./experiment/bar.yml

Answer 1

As comments suggests, i end up using the following:

experiment/gen__*/*
!experiment/foo.sh
!experiment/bar.yml

The important thing is to use the naked directory name :

• correct: experiment/
• incorrect: ./experiment/

Answer 2

experiment/gen__* should be enough as the following example shows:

~$ mkdir test
~$ cd test
~/test$ git init
Initialized empty Git repository in /home/mh/test/.git/
~/test$ touch foo.sh
~/test$ touch bar.yml
~/test$ mkdir gen__20190425_144843
~/test$ touch gen__20190425_144843/1
~/test$ touch gen__20190425_144843/2
~/test$ mkdir gen__20190425_144854
~/test$ touch gen__20190425_144854/3
~/test$ touch gen__20190425_144854/4
~/test$ tree
