![GeeXbox ls 没有显示日期?](https://linux22.com/image/37015/GeeXbox%20ls%20%E6%B2%A1%E6%9C%89%E6%98%BE%E7%A4%BA%E6%97%A5%E6%9C%9F%EF%BC%9F.png)
最近,我尝试通过 WinSCP 连接到我的 GeeXbox,但收到错误,指示ls
无法解析 的输出。
显然,我的ls
不包含时间戳!可能是什么原因以及我该如何纠正?请参阅下面的示例输出:
$ ls -la
total 96
drwxrwxr-x 17 root root 4096 .
drwxrwxr-x 17 root root 4096 ..
lrwxrwxrwx 1 root root 7 bin -> usr/bin
-rw-rw-r-- 1 root root 39779 config
drwxr-xr-x 13 root root 3980 dev
drwxrwxr-x 29 root root 4096 etc
我的特别ls --help
优惠是:
$ ls --help

通常,作为“专用设备”的系统会使用名为 BusyBox 的工具。您可以阅读更多有关BusyBox项目,但简而言之,该项目提供了典型工具的精简版本,例如ls
等。
在我安装的也使用 BusyBox 的 XBMC 上,ls
当我执行ls -l
.还有一个额外的开关-e
可以生成时间日期信息。
# ls --help
BusyBox v1.21.0 (2013-01-22 19:16:54 CET) multi-call binary.

-u With -l: sort by atime
-w N Assume the terminal is N columns wide

所以我假设您遇到了两种情况之一。
- 您的 BusyBox 版本在输出中不包含时间戳
-l
。顺便说一句,我怀疑情况是否如此。 mount
由于必须跟踪此信息所涉及的开销,文件系统通过选项禁用了时间戳跟踪。
例如,有一些选项noatime
将禁用文件系统上的访问时间跟踪。
$ mount -v
/dev/mmcblk0p1 on /flash type vfat (ro,noatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro)
