从主机名中提取文本 [英] Extract text from hostname

问题描述

使用OS X，我需要一个bash脚本来查看客户端mac主机名，例如: 12345-BA-PreSchool-LT.local

Using OS X, I need a one line bash script to look at a client mac hostname like: 12345-BA-PreSchool-LT.local

前5位数字是资产序列号，连字符将业务单位代码与部门名称分隔开，后跟类似"LT"的符号来表示便携式计算机.

Where the first 5 digits are an asset serial number, and the hyphens separate a business unit code from a department name followed by something like 'LT' to denote a laptop.

我想我需要回显主机名，并结合使用sed，awk和也许要切掉的字符以使我离开:
"BA PreSchool"

I guess I need to echo the hostname and use a combination of sed, awk and perhaps cut to strip characters out to leave me with:
"BA PreSchool"

任何帮助，不胜感激.这是我到目前为止的内容:

Any help much appreciated. This is what I have so far:

echo $HOSTNAME | sed 's/...\(...\)//' | sed 's/.local//'

推荐答案

 echo "12345-BA-PreSchool-LT.local" | cut -d'-' -f2,3 | sed -e 's/-/ /g'

(不在OSX上，因此不确定是否定义了剪切)

(Not on OSX, so not sure if cut is defined)
