Question

我因为必须在工作中使用Powershell而陷入困境。我已将我的代码和结果附加到目前为止。

$data = Get-Content "/Users/mikeshobes/Documents/Powershell/nfl.csv"

write-host $data.count total lines read from file
foreach ($line in $data)
{
    write-host $line
}

13 total lines read from file

Answer 1

如果您想得到的是一行中每个单词在该行中的次数，首先需要将单词中的行拆分为a然后获取该单词在该行中的次数。

我认为一段代码可以更好地解释它：

key1=value1&key2=value2&key3=value3

如何计算每行上每个单词的出现次数？
