Powershell，从txt文件中读取并格式化数据(删除行，删除它们之间的空格) [英] Powershell ,Read from a txt file and Format Data( remove lines, remove blank spaces in between)

问题描述

我对 powershell 真的很陌生.我想用powershell读取一个txt文件，改成另一种格式.

I am really very new to powershell. I want to use powershell to read a txt file and change it to another format.

1. 从 txt 文件中读取.
2. 格式化数据(删除行，删除中间的空格)
3. 记录数(T 000000002"9 个字符)

然后将输出写入新文件.

and then write the output to a new file.

两天前我刚刚启动了 powershell，所以我还不知道如何做到这一点.

I just started powershell two days ago so I don't know how to do this yet.

推荐答案

function Count-Object() {
    begin {
        $count = 0
    }
    process {
        $count += 1
    }
    end {
        $count
    }
}

$a= get-content .\members.txt |  
Foreach-Object { ($_  -replace '\s','') } |
Foreach-Object { ($_ -replace '-','') } |
Foreach-Object { ($_ -replace 'OP_ID','') } | 
Foreach-Object { ($_ -replace 'EFF_DT','') } |
Where-Object { $_ -ne '' }|
set-content  .\newmembers.txt

 $b = Get-Content  .\newmembers.txt |
Count-Object $b 
 "T {0:D9}" -f $b | add-content  .\newmembers.txt
