Renaming files using a strings from a txt file - string

Question

The question might sound confusing but all I really need is the ability to change a file name using an array of strings.
For example:
File 1 contains:
abc1234cd.jpg
abc2543ac.jpg
...
File 2 contains (array/reference)
1234c
2543a
...
The new file name for abc1234cd.jpg should now be 1234c.jpg and so forth.
Is this possible with powershell or any other language to do?
Thanks,

Answer 1

This should do it, assuming the files have a one-to-one match.
# Get contents of file 1
$File1 = Get-Content -Path $PSScriptRoot\File1.txt;
# Get contents of file 2
$File2 = Get-Content -Path $PSScriptRoot\File2.txt;
# Iterate over each item in $File1
foreach ($Item in $File1) {
$FileList = Get-ChildItem -Path "c:\test\$Item*.jpg";
foreach ($File in $FileList) {
# Determine file's new name, based on corresponding value in File2
$NewName = $File.Name -replace $Item, $File2[$File1.IndexOf($Item)];
Write-Host -Object ('Old name: {0}, new name: {1}' -f $Item, $NewName);
}
}

Answer 2

After countless hours, I finally got the code to work.
$dir = 'file.txt'
$backup = 'C:\Users\all users\Desktop\backup'
$file = 'file2.txt'
$files = Import-Csv -Header Name -Path $file
foreach ($line in $files){
$linefiles = Get-ChildItem $dir | where {$_.BaseName.Contains($line.Name)}
$count = 0
foreach ($linefile in $linefiles) {
#do stuff to each file here
$name = $linefile.BaseName
$extension = $linefile.Extension
$newName = $line.Name
Copy-Item -Path "$dir\$linefile" -Destination "$backup\$linefile"
if ($count -gt 0){
Rename-Item -NewName "$newName-$count$extension" -Path "$dir\$linefile"}
else{
Rename-Item -NewName "$newName$extension" -Path "$dir\$linefile"}
$count++}
}
