2条件得到满足后，提取文本文件数据 [英] Extracting data from text file after 2 conditions have been met

问题描述

我工作的一个bash脚本在从 carslist.txt 称为一个文本文件，其中每节车厢（及其相应的特征）正对中提取数据的时刻单独的行。我已经能够提取并从文本文件保存数据它遇到了一个单一的条件（以下举例）之后，但我无法弄清楚如何做到这一点的两个条件。

I'm working on a bash script at the moment which extracts data from a text file called carslist.txt, which each car (and its corresponding characteristics) being on separate lines. I've been able to extract and save data from the text file after it's met a single condition (below for example) but I can't figure out how to do it for two conditions.

单条件例如：

的grep'Vauxhall的'$ CARFILE＆GT;输出/ Vauxhall_Cars.txt

输出：

Vauxhall:Vectra:1999:White:2
Vauxhall:Corsa:1999:White:5
Vauxhall:Cavalier:1995:White:2
Vauxhall:Nova:1994:Black:8

从上面的例子中，我将如何提取，如果我想的条件数据沃克斯豪尔和白色来得到满足提取面前？

From the examples above, how would I extract data if I wanted the conditions Vauxhall and White to be met before extracting them?

grep的例子上述要求沃克斯豪尔拉动和保存数据之前必须满足，但我不知道该怎么做了。我已经试过流水线命令为沃克斯豪尔|白但在那之后我的想法。

the grep example above asks for Vauxhall to be met before pulling and saving the data, but I have no idea how to do it for 2. I've tried pipelining the command as Vauxhall | White but after that I was out of ideas.

先谢谢了。

推荐答案

我会建议使用 AWK ，就像这样：

I would recommend to use awk, like this:

awk -F: '$1=="Vauxhall" && $4=="White"' input.file

由于我使用：作为字段分隔符，我只需要检查场1和4的值

As I'm using : as the field separator, I simply need to check the values of field 1 and 4.
