如何在powershell

Question

我正在使用PowerShell编写监控报告。该脚本提取服务器详细信息，磁盘状态和应用程序状态。

我能够在HTML表格中通过邮件发送服务器详细信息和磁盘状态。但是读取文件的内容（通过从Oracle DB中提取数据的批处理文件创建）并通过HTML格式的相同邮件发送它不起作用。

以下是文本文件中的数据：

**program-id        sta pid        start time           stop time**

Clnt_dp           T   0          04/03/2017 08:00:03  04/03/2017 08:00:04
Clnt_ds           R   5140       04/03/2017 08:00:03  
Clnt_rpc          R   8572       04/03/2017 08:00:03  
bksrvr            R   4692       04/03/2017 07:59:03  
chkw              T   0          04/03/2017 07:59:03  04/03/2017 08:09:04
db                T   0          04/03/2017 07:59:01  04/03/2017 07:59:02
dsaux             R   8444       04/03/2017 07:59:03  
dssched           R   4792       04/03/2017 07:59:03  
dsshares          R   7672       04/03/2017 07:59:03  
ixmonSvc          R   5552       04/03/2017 07:59:03  
jbd               R   7536       04/03/2017 07:59:02  
migration         R   476        04/03/2017 07:59:03  
notifSrvr         R   1220       04/03/2017 07:59:03  
timestamp         R   8928       04/03/2017 07:59:02  

任何人都可以让我知道如何实现这一目标？感谢。

您需要以固定宽度间隔分割字符串。使用您的文本文件摘录，模仿Get-Content：

cls
$content = @'
**program-id        sta pid        start time           stop time**

Clnt_dp           T   0          04/03/2017 08:00:03  04/03/2017 08:00:04
Clnt_ds           R   5140       04/03/2017 08:00:03  
Clnt_rpc          R   8572       04/03/2017 08:00:03  
bksrvr            R   4692       04/03/2017 07:59:03  
chkw              T   0          04/03/2017 07:59:03  04/03/2017 08:09:04
db                T   0          04/03/2017 07:59:01  04/03/2017 07:59:02
dsaux             R   8444       04/03/2017 07:59:03  
dssched           R   4792       04/03/2017 07:59:03  
dsshares          R   7672       04/03/2017 07:59:03  
ixmonSvc          R   5552       04/03/2017 07:59:03  
jbd               R   7536       04/03/2017 07:59:02  
migration         R   476        04/03/2017 07:59:03  
notifSrvr         R   1220       04/03/2017 07:59:03  
timestamp         R   8928       04/03/2017 07:59:02 
'@
$content -split "`r*`n" |
  select -Skip 2 -Property  @{name='program-id';expression={$_.Substring(0 ,17).Trim()}}, #1st
                            @{name='sta';       expression={$_.Substring(18,4).Trim()}},  #2nd 
                            @{name='pid';       expression={$_.Substring(22,11).Trim()}}, #3rd
                            @{name='start time';expression={$_.Substring(33,19).Trim()}}, #4th
                            @{name='stop time'; expression={$_.Substring(54).Trim()}} |   #5th
  ConvertTo-Html

...并使用Get-Content ...

Get-Content -Path 'c:\path\to\file.txt' |
  select -Skip 2 -Property  @{name='program-id';expression={$_.Substring(0 ,17).Trim()}}, #1st
                            @{name='sta';       expression={$_.Substring(18,4).Trim()}},  #2nd 
                            @{name='pid';       expression={$_.Substring(22,11).Trim()}}, #3rd
                            @{name='start time';expression={$_.Substring(33,19).Trim()}}, #4th
                            @{name='stop time'; expression={$_.Substring(54).Trim()}} |   #5th
  ConvertTo-Html

Answer 2

使用此ConvertFrom-SourceTable cmdlet：

$content -split '[\r\n]+' | Foreach-Object {$_.Trim('*')} |
ConvertFrom-SourceTablel | Format-Table # or ... | ConvertTo-Html

program-id sta pid  start time          stop time
