DOS batch file, change numbers within a text file

I'm not familiar with Powershell.

Where do I paste, and how do I run it .  Thanks

@hgj1357: you need to paste it in the lower window

How do I run it?

BTW, if you want to keep the 3 decimals (as in 2827500.250) you need to modify the code like this:

Param (
[string]$inputPath = "X:\path\to\your\files"
)

$files = Get-ChildItem $inputPath -Filter *.txt
foreach ($file in $files)
{
    $text=gc $file.Fullname
    $text[-2] = "{0:F3}" -f (4.75 + $text[-2])
    $text[-1] = "{0:F3}" -f (-4.75 + $text[-1])
    $text > $file.FullName
}

Select allOpen in new window

Save the code as whatever.ps1 and run it as whatever.ps1 X:\your\path

OR, change X:\path\to\your\files to your actual path, paste the entire script in the lower pane of the Powershell ISE window and then press ENTER.

This works - nearly.  The resultant text file is some kind of ANSI format that I can not use further. (In AutoCAD).  If I open and save as ANSI encoded file type, it then works again.  Is there a way to bulk change the encoding type to ANSI?

Run this in powershell:

Get-ChildItem "X:\path\to" -Filter *.txt | % { (Get-Content $_.fullname) | Set-Content $_.fullname -Force -Encoding ASCII}

Select allOpen in new window

Of course, change X:\path\to to your actual path.

I used type File>Newfile.txt to fix issue.

All good.

Thanks

Removed MSDOS Topic and added Powershell Topic since the accepted solution is not an MSDOS based solution.
