如果变量与行中的一部分匹配，则显示文本文件中的一行？

如果变量与行中的一部分匹配，则显示文本文件中的一行？

我正在做一个库存检查器。我有一个包含所有纽约证券交易所及其描述的文件。描述从文件的第一个选项卡输入开始。文件格式如下所示：

A       Agilent Technologies
AA      Alcoa Inc
AA-B    Alcoa Inc.
AAC     Aac Holdings Inc.
AAN     Aaron's Inc
AAP     Advance Auto Parts Inc
AAT     American Assets Trust
AAV     Advantage Oil & Gas Ltd
AB      Alliance Capital Management L.P.
ABB     Abb Ltd
ABBV    Abbvie Inc. Common Stock
ABC     Amerisourcebergen Corp
ABEV    Ambev S.A.
...

我想要这样，当输入股票时，它会显示该股票的描述，如下所示（输入stockchecker AB）：

Stock: AB (NYSE) - Alliance Capital Management L.P.

我还有一份所有纳斯达克交易所的文件。

如何检查两个文件以查看其是否与第一个参数（输入的股票代码）匹配，然后显示说明？ （文本文件名为NYSE.txt和NASDAQ.txt）代码（如果需要）：

#!/bin/bash
stock=$1
touch info.txt # create info.txt if missing
touch raw-info.txt # create raw-info.txt if missing
echo $( wget http://www.google.com/finance/info?q=NASDAQ%3a$stock -q -O -) > raw-info.txt # get the information from Google Finance and write it to info.txt
tr "\" ," "\n" < raw-info.txt > info.txt # split the information from Google Finance into separate lines

这是一种解决方案 -

    #!/bin/bash
    grep "^$1 " NYSE.txt NASDAQ.txt | sed 's/:/ /' | awk '{printf "Stock %s ( %s ) -  ",$2,$1; for(i=3;i<NF;i++) printf "%s ",$i OFS;if(NF)printf"%s",$NF;printf ORS}'

第一个 grep 搜索以符号开头的行。 sed 将 get 输出的文件名后面的“：”替换为空格。 awk 按照您想要的顺序打印句子。
