Get-Content Add-Content

JSHACHER11 — Thu, 05 Jun 2025 05:27:55 GMT

Hi guys,

I am trying to pull data from one file to another

This works fine:

gc "c:\file1.txt" | ? {$_ -match "lun:/vol/"} | Add-Content "c:\file2.txt"

but this fails:

$source = Read-Host "enter full path to source file"
$dest = Read-Host "enter full path to destination file"

gc $source | ? {$_ -match "lun:/vol/"} | Add-Content $dest

Get-Process : A positional parameter cannot be found that accepts argument 'gc'.
At C:\perf_file.ps1:11 char:3
+ PS <<<< C:\> gc $source | ? {$_ -match "lun:/vol/"} | Add-Content $dest
+ CategoryInfo : InvalidArgument: (:) [Get-Process], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.GetProcessCommand

what am I doing wrong?

Thank you

Joel

it's just a text file with performance information

for example, the file contains a lot of lines about 'volume' stats and I want to take only the lines that say 'read_align_histo' and put it in a different file

like I said, it works fine, it's just when I use the 'Read-Host' that it fails

Cheers

Hello Joel,

Can you use the Get-Content cmdlet name itself in place of "gc", also please check if the alias is pointing to get-process.

This is how the the output for the alias gc should show up

PS C:\> Get-Alias -Name gc

CommandType Name ModuleName
----------- ---- ----------
Alias gc -> Get-Content

I tried it in my lab and it worked fine, i guess there is some issue with the alias redirecting itself to "Get-Process"

Thanks,

Vinith

my fault. my script was like this:

PS C:> gc ...

instaed of:

gc ..

POSH didn't know how to read the 'PS' (obviously)
