issues "using ls -al --full-time" in OSX
提问by C0ppert0p
--full-timeis a handy little option for lsbut it doesn't work when used in a batch file.
--full-time是ls 的一个方便的小选项，但在批处理文件中使用时它不起作用。
ls -al --full-timewhen used at the command prompt yields a an expanded date and time:
ls -al --full-time在命令提示符下使用时会产生扩展的日期和时间：
2012-01-16 18:56:00.000000000
2012-01-16 18:56:00.000000000
used in a bash script I got this:
在 bash 脚本中使用我得到了这个：
ls: illegal option -- - usage: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [file ...]
ls: 非法选项 -- -- 用法: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [文件...]
is there any way around this.
有没有办法解决。

for native lscommand, option -Tseems to be the alternative of --full-time, and it expands to seconds, example as below:
对于本机ls命令， option-T似乎是 的替代--full-time，它扩展到秒，示例如下：
>$ ls -lT

The BSD (Mac OS X) version of ls(installed as /usr/bin/ls) does not support the --full-timeoption.
BSD (Mac OS X) 版本ls（安装为/usr/bin/ls）不支持该--full-time选项。
The GNU version of lsdoes support --full-time. I have the GNU lsinstalled in a different directory (/usr/gnu/bin/ls).
的 GNU 版本ls确实支持--full-time. 我将 GNUls安装在不同的目录 ( /usr/gnu/bin/ls) 中。
- Are you sure that you have GNU
lson your machine at all? - If so, are you sure your PATH includes the directory where it is installed ahead of
/usr/binwhen you run scripts?
- 你确定
ls你的机器上有 GNU吗？ - 如果是这样，您确定您的 PATH 包含
/usr/bin在您运行脚本之前安装它的目录吗？

ls: illegal option -- -
usage: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [file ...]
Are you sure your lsisn't actually glsinstalled by homebrew?
您确定您ls实际上不是gls由自制软件安装的吗？
