问题描述

| 我正在尝试创建一个Powershell脚本，该脚本将获取计划任务的列表。我已经足够拿到完整的任务列表，但是我需要删除结尾的“ ...” 你是怎样做的？

$tasks | Select-String -pattern \"disabled\" | ft @{Expression
={$_.Line};Label=\"Line\";width=44}

输出：

解决方法

        不要使用Format-Table（ft），因为它会尝试将数据容纳在控制台中可用的列数之内，并且您已将“ line”列的空间限制为44个字符。尝试以下方法：

$tasks | Select-String -pattern \"Disabled\" | Foreach {$_.Line}

    ,        

$tasks | Select-String -pattern \"Disabled\" | ForEach-Object
{ $_ -replace \"Disabled\",\"\"} | ForEach-Object { $_ -replace \"Could not start\",\"\"} | ForEach-Object { $_.Trim() }

完全符合我的要求。     ,        我不确定其中包含什么$ tasks，因此我根据get-service编写了此代码，但它在您的情况下应该可以使用：

$tasks | Select-String -pattern \"Disabled\" | ft @{Expression=
{$intLength = 44; if($_.Line.length -lt $intLength) {$intLength=$_.Line.length} $_.Line.substring(0,$intLength)};Label=\"Line\"}
