Powershell: Replace string in File1 based on string in File2

Question

I am being forced to use Powershell because of my work. I have used it to do a couple of things but one of my codes is now trash because I have to update a string in a file to include a year that is in a second file. Here is what I'm working with:

File1: Contains a few strings but in there is 48 strings that say:
Jenga_Sequence-XXXX.consensus_Bob_0.6_quality_20

The main point of the string is Sequence-XXXX , sorry for the random place holders.

File2: is a table that has the strings:
John/USA/Sequence-XXXX/Year

I need to replace the strings in File1 with the corresponding Strings in File2.

Sample Text of File1:

Jenga_Sequence-0001.consensus_Bob_0.6_quality_20
AAAAAAAAAAAAAAAAAAAAAAAAA
Jenga_Sequence-0002.consensus_Bob_0.6_quality_20
aaaaaaaaaaaaaaaaaaaaaaaaa
Jenga_Sequence-0003.consensus_Bob_0.6_quality_20
bbbbbbbbbbbbbbbbbbbbbbbbb
Jenga_Sequence-0004.consensus_Bob_0.6_quality_20
BBBBBBBBBBBBBBBBBBBBBBBBB
Jenga_Sequence-0005.consensus_Bob_0.6_quality_20
QQQQQQQQQQQQQQQQQQQQQ

Sample Table of File2:

|Sequence_ID|Date|
|---------------------------|----------|
|John/USA/Sequence-0003/2020|10/11/2020|
|John/USA/Sequence-0001/2021|1/5/2021|
|John/USA/Sequence-0005/2021|1/10/2021|
|John/USA/Sequence-0004/2020|12/23/2020|
|John/USA/Sequence-0002/2021|1/6/2021|

So, I need a Powershell code that replaces
Jenga_Sequence-0001.consensus_Bob_0.6_quality_20 with John/USA/Sequence-0001/2021 ,
Jenga_Sequence-0002.consensus_Bob_0.6_quality_20 with John/USA/Sequence-0002/2021 ,
Jenga_Sequence-0003.consensus_Bob_0.6_quality_20 with John/USA/Sequence-0003/2020 , and so on. There are typically 48 of these in a file.

My previous code simple replaced "Jenga_" with "John/USA/" and ".consensus_Bob_0.6_quality_20" with "/2020" but now that we are seeing "/2021" the static code will not work.

I am still open to replacing pieces of the string and having a code that sets the year replacement to the correct year.

That was the angle I was doing a broad search on but I could never find anything specific enough to help.

Any help will be appreciated!

EDIT: Here is the part of my previous code that dealt with the finding and replacing, even though I feel it needs to be trashed:

$filePath = 'Jenga_Combined.txt'
$tempFilePath = "$env:TEMP\$($filePath | Split-Path -Leaf)"
$find = 'Jenga_'
$replace = 'John/USA/'
$find2 = '.consensus_Bob_0.6_quality_20'
$replace2 = '/2020'

(Get-Content -Path $filePath) -replace $find, $replace -replace $find2, $replace2 | Add-Content -Path $tempFilePath

Remove-Item -Path $filePath
Move-Item -Path $tempFilePath -Destination $filePath

EDIT2: The "Real Data" from file2. File2 is a Tab Delimited.txt file which makes it not "look great" when copy and pasting. Hopefully this helps. File1 is exactly like above (although the AAAAA stuff is roughly 30,000 letters long)

Sequence_ID date
John/USA/Sequence-0003/2020 2020-10-11
John/USA/Sequence-0001/2021 2021-01-05
John/USA/Sequence-0005/2021 2021-01-10
John/USA/Sequence-0004/2020 2020-12-23
John/USA/Sequence-0002/2021 2021-01-06

Answer 1

The common factor here is the Sequence_ID number in both files. You can do this like:

$csvData = Import-Csv -Path 'D:\Test\File2.txt' -Delimiter "`t"

$result = switch -Regex -File 'D:\Test\Jenga_Combined.txt' {
    '^Jenga_Sequence-(\d+).*' {
        $replace = $csvData | Where-Object { $_.Sequence_ID -like "*Sequence-$($matches[1])*" }
        if (!$replace) { Write-Warning "No corresponding Sequence_ID $($matches[1]) found!"; $_ }
        else { $replace.Sequence_ID }
    }
    default { $_ }
}

# output on screen
$result

# output to new file
$result | Set-Content -Path 'D:\Test\Jenga_Combined_NEW.txt' -Force

Output on screen:

John/USA/Sequence-0001/2021
AAAAAAAAAAAAAAAAAAAAAAAAA
John/USA/Sequence-0002/2021
aaaaaaaaaaaaaaaaaaaaaaaaa
John/USA/Sequence-0003/2020
bbbbbbbbbbbbbbbbbbbbbbbbb
John/USA/Sequence-0004/2020
BBBBBBBBBBBBBBBBBBBBBBBBB
John/USA/Sequence-0005/2021

Of course, you need to change the file paths to match your environment
