-3

我正在尝试使用 bash 脚本读取 .dat 文件。

该值包含我想要grep值大于0的文件大小，第一列除外。大于零的值可以出现在任何行中。

I have awk script to read line by line.

如果我了解您的需求：

awk -F"," '{for (i=2;i<=NF;i++){if ($i > 1) {print}}}' file.dat

输出

如果您想获取此文件中每行（基于您的输入）的每 13 列（即 14353）、第 16 列（即 450.03）和第 19 列（即 69832）的内容，请尝试以下操作：

awk < test.dat -F ', ' '{print $13,$16,$19}'

在test.dat您的数据文件中的位置。

这将输出：

14353 450.03 69832
0 0 0
0 0 0
14353 450.03 68552
0 0 0
14353 450.03 73826

据我了解，您希望 grep 包含除 0 或 1 以外的数字的所有行，不计算行首的第一个数字。怎么样

egrep ',.*([2-9]|[0-9.]{4,})' tmp.txt

这将从您的示例中打印出以下行

1349939700, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 14353, 1, 0, 450.03, 2, 0, 69832, 0, 0, 0, 0, 0
1349939880, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 14353, 1, 0, 450.03, 1, 0, 68552, 0, 0, 0, 0, 0
1349940000, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 14353, 1, 0, 450.03, 1, 0, 73826, 0, 0, 0, 0, 0
