[求助] ls -l 的输出

singsm

我在用ls -l 查看文件信息时,发现有些文件或文件夹的修改时间显示的是年份,其他的则是hh:mm的格式! 请问这是为什么? BUG吗？能解决吗？

1. see if your ls is an alias. Normally, SuSE likes to create a default alias for ls. Call "/bin/ls -l" to see the default behavior.
2. see what version you are using. It may have slightly different implementation.
3. the "--time-style" can be altered. The format is in man page.

man ls

-l中有明确说明：
If the time of last modification is greater than six months ago, the time field is shown in the format month date year where as files modified within six months the time field is shown as month date time format.
