Get-ChildItem Zero Results Output - powershell

Question

I have an issue that I cannot resolve no matter which way I am wrapping it up. I am including my latest code which is not giving me the desired outcome and the code for a solution that does work but for only one file at a time. I cannot work out how to loop through each of the files automatically however.
In a nutshell, I have a directory with many CSV files some of the entries within the CSVfile have a negative value (-) I need to remove this minus sign in all instances.
Now what works is if I use the following (on a single file)
$content = Get-Content "L:\Controls\BCR\0001cash.csv" | ForEach {$_ -replace $variable, ""} | Set-Content "L:\controls\bcr\0001temp.csv"
What I am trying to do is iterate through the many thousand of these objects automatically and not have to refer to them individually.
I started with:
$Directory = "L:\Controls\BCR\"
$variable = "-"
$suffix = ".tmp"
To define the directory, minus symbol that I want to remove and the suffix of the file I want to change to...
$Files = Get-ChildItem $Directory | Where-Object {$_.Extension -like "*csv*"} | Where-Object {$_.Name -like "*cash*"}
Is obtaining each of the files that I wish to work with
And I am then working with
ForEach ($File in $Files) { Get-Content $Files | ForEach {$_ -replace $variable, ""} | Set-Content {$_.Basename + $Variable}
The results however are nothing...
At a loss? Anyone???
$Directory = "L:\Controls\BCR\"
$variable = "-"
$suffix = ".tmp"
$Files = Get-ChildItem $Directory | Where-Object {$_.Extension -like "*csv*"} | Where-Object {$_.Name -like "*cash*"}
$process = ForEach ($File in $Files) { Get-Content $Files | ForEach {$_ -replace $variable, ""} | Set-Content {$_.BaseName + $suffix}
}

Answer 1

You are using the wrong variable in the Get-Content cmdlet ($Files instead of $File). Also You can simplify your script:
$Directory = "L:\Controls\BCR\"
$variable = "-"
$suffix = ".tmp"
Get-ChildItem $Directory -Filter '*cash*csv' |
ForEach-Object {
(Get-Content $_ -Raw) -replace $variable |
Set-Content {$_.BaseName + $suffix}
}
