1. git status
有提示文件修改 例如：
[jason@vm-www1 d]$ git status
# On branch master
# Changed but not updated:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: theme-images.php
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# ../../../nginx.conf
no changes added to commit (use "git add" and/or "git commit -a")
2. 使用git diff theme-images.php
任何输出都没有
3. 解决方法：
---------------------- 未配置账号、邮箱 使用以下命令设置--------------------------------
git config --global user.name "jason" #修改
git config --global user.email "json@fu101.com" #修改
-------------------------------------------------------------
git --no-pager diff theme-images.php
有修改的日志
git config --global core.pager "more"
