Use the datecommand with a format like this:
使用具有如下格式的date命令：
date +"%m/%d/%Y %H:%M:%S $HOSTNAME"
To get hundredths of seconds, you may need to do some text processing like this:
要获得百分之几秒，您可能需要像这样进行一些文本处理：
DATE=date +'%m/%d/%Y %H:%M:%S.%N'
DATE=${DATE%???????}
DATE="$DATE $HOSTNAME"
This is because date offers seconds, nanoseconds, and nothing in between!
这是因为 date 提供秒、纳秒以及介于两者之间的任何内容！

In Linux, there is the datecommand. If you don't like the default format, it can be modified. See the manpage of date
在 Linux 中，有date命令。如果您不喜欢默认格式，可以对其进行修改。请参阅日期的联机帮助页
For hostname, you can use hostnamecommand, or $HOSTNAMEenvironment variable, if it is set.
对于主机名，您可以使用主机名命令或$HOSTNAME环境变量（如果已设置）。
With system name, it is more complicated. You can use uname -a, sometimes it contains the OS name. Some distributions also have lsb-release, but not all of them.
有了系统名，就更复杂了。您可以使用uname -a，有时它包含操作系统名称。一些发行版也有lsb-release，但不是全部。

Several people have provided answers based on date, but your question requires the short day name (although my UK Win 7 installation doesn't provide this with the ECHO command you specified), which no one has (so far) addressed.
有几个人提供了基于 的答案date，但是您的问题需要简短的日期名称（尽管我的 UK Win 7 安装没有通过您指定的 ECHO 命令提供此名称），但没有人（到目前为止）解决过这个问题。
To get this, you will probably want to include %ain the format string:
为此，您可能希望%a在格式字符串中包含：
date "+%a %m/%d/%Y %H:%M:%S $HOSTNAME"

it is also possible to use backtiks caracters for this:
也可以为此使用 backtiks 字符：
echo `date` `hostname`
or with (localised) date formating:
或使用（本地化）日期格式：
echo `date +"%a %x %X"` `hostname`

echo $(date '+%Y %b %d %H:%M') Your output $HOSTNAME
Outputs:
输出：
2013 Nov 01 09:11 Your output PEGASUS-SYDNEY-CL2
