Bid[price:3195 qty:450] Ask[price:3215 qty:600].
Bid[price:3195 qty:450] Ask[price:3215 qty:600].
Bid[price:3195 qty:450] Ask[price:3215 qty:600].
Bid[price:3195 qty:450] Ask[price:3210 qty:75].
Bid[price:3195 qty:450] Ask[price:3215 qty:600].
Bid[price:3195 qty:525] Ask[price:3215 qty:600].
Bid[price:3195 qty:75] Ask[price:3215 qty:600].
Bid[price:3195 qty:75] Ask[price:3215 qty:600].

请告诉我如何使用终端从 .txt 文件中提取它。

答案1

不需要正则表达式引擎的解决方案：

$ cut -d ' ' -f 6- logfile

在这种情况下，该cut实用程序将为您提供从第六列开始的所有列。它将把每行上的每个空格视为列分隔符。

答案2

这可能是一个非常简单的问题。如果您只想从“Bid”一词开始到行尾，您可以使用：

grep -o 'Bid.*' yourfile.txt

答案3

和awk：

awk '{ print $6$7$8$9 }' logfile
