最近在使用git时遇到一个问题， push到远程机器上时某个log文件夹丢失了，本地查找是有的，git status也显示clean：
$ git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean于是猜测可能是被.gitignore过滤了，打开之后果然，里面有一行：
log/这一行本来是用来过滤当前目录的的log文件夹，结果其他地方的log文件夹也被过滤了，解决： 指明当前文件夹，改为：
/log此时在git status就发现那个我想加入git的log文件夹出现了
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes not staged for commit:

modified: .gitignore
Untracked files:
(use "git add <file>..." to include in what will be committed)
src/main/java/sysu/newchain/consensus/pbft/msg/log/
no changes added to commit (use "git add" and/or "git commit -a")
