How to apply condition to a string in the multiple string with powershell

Question

I am trying to make a txt file and apply some content to a multiple string

this is what I did so far:

$Filename = "Jessica,Jimmy,Adam"
$Content = ({Whoisthesmartest=})
$Splitname = get-childitem $Filename -split "," 
new-item c:\test.txt -itemtype file -value $Content + $Splitname

But that didn't work.

what I'm trying to achieve is a txt file that has content:

Whoisthesmartest=Jessica
Whoisthesmartest=Jimmy
Whoisthesmartest=Adam

Answer 1

• You need to process the elements of array $SplitName individually, which you can do by enumerating it in the pipeline ...

• ... processing each element via ForEach-Object ...

• ... and saving the results to an output file with Set-Content

  • Note that Set-Content quietly overwrites an existing file, which New-Item only does if you add -Force.

$Filename = "Jessica,Jimmy,Adam"
$Content = 'Whoisthesmartest='    # Note: Use a *string*, not {...}
$Splitname = $Filename -split "," # No need for Get-ChildItem - unless I'm missing something.

$Splitname | 
  ForEach-Object { $Content + $_ } |
  Set-Content c:\test.txt

As for what you tried:

$Content = ({Whoisthesmartest=})

This assigns a script block ({ ... }) (needlessly wrapped in (...)) to $Content, whereas you're looking for a string:

$Content = 'Whoisthesmartest='

... -value $Content + $Splitname

$Content + $Splitname is an expression, and in order for an expression to function as a command argument, it must be enclosed in (...):

... -value ($Content + $Splitname)

$Splitname = get-childitem $Filename -split ","

Since $SplitName is a string you want to split, there's no reason to involve Get-ChildItem; apart from that, the statement has the same problem as described above: expression $Filename -split "," lacks (...) enclosure.
