Powershell检查每行的第一个字符的具体值 [英] Powershell check first character of each line for specific value

问题描述

我正在阅读包含特定格式数字的文本文件。我想弄清楚该行的第一个字符是6还是4，并将整个行存储在数组中供以后使用。所以如果行以6开头，将整行添加到sixArray中，如果该行以4开头，则将整行添加到fourArray中。

I am reading in a text file that contains a specific format of numbers. I want to figure out if the first character of the line is a 6 or a 4 and store the entire line in an array for use later. So if the line starts with a six add the entire line into sixArray and if the line starts with a 4 add the entire line into fourArray.

如何检查第一个字符，然后抓取该行上的其余X个字符？不替换任何数据？

How can I check the first character and then grab the remaining X characters on that line? Without replacing any of the data?

推荐答案

这样的东西可能会工作。

Something like this would probably work.

$sixArray = @()
$fourArray = @()

$file = Get-Content .\ThisFile.txt
$file | foreach { 
    if ($_.StartsWith("6"))
    {
        $sixArray += $_
    }

    elseif($_.StartsWith("4"))
    {
        $fourArray += $_
    }
}
