The command is date
命令是 date
To customise the output there are a myriad of options available, see date --helpfor a list.
要自定义输出，有许多可用选项，请参阅date --help参考资料。
For example, date '+%A %W %Y %X'gives Tuesday 34 2013 08:04:22which is the name of the day of the week, the week number, the year and the time.
例如，date '+%A %W %Y %X'给出Tuesday 34 2013 08:04:22星期几的名称、星期数、年份和时间。

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST -0.516080 seconds
For customized output, you can either redirect the output of dateto something like awk, or write your own program to do that.
对于自定义输出，您可以将 的输出重定向date到类似的内容awk，或者编写自己的程序来执行此操作。
Remember to put your own executable scripts/binary into your PATH(e.g. /usr/bin) to make it invokable anywhere.
请记住将您自己的可执行脚本/二进制文件放入您的PATH（例如 /usr/bin）中，以使其可在任何地方调用。
