事实上，git diff应该显示您的更改，但有时不会由于寻呼机错误而显示。要检查这一点，请执行以下操作：
git --no-pager diff
如果它显示某些内容，请将寻呼机设置回简单的内容：
git config --global core.pager less
在您给出的配置中，您的寻呼机是：
core.pager=less -E
根据男人少
-E or --QUIT-AT-EOF Causes less to automatically exit the first time it reaches end-of-file.
这意味着，如果您的更改小于终端高度，less会分页它们并在备用屏幕缓冲区打开时立即退出：
在 VT102 模式下，有转义序列来激活和停用备用屏幕缓冲区，该缓冲区的大小与窗口的显示区域相同。激活后，当前屏幕将被保存并替换为备用屏幕。在恢复正常屏幕之前，将禁用从窗口顶部滚动的行的保存。xterm 的 termcap(5( 条目允许可视化编辑器 vi(1( 切换到备用屏幕进行编辑，并在退出时恢复屏幕。弹出菜单项使在正常屏幕和备用屏幕之间切换以进行剪切和粘贴变得简单。
