How to add text to existing text in a csv file using PowerShell - powershell

Question

I have a csv file that contains one column of cells (column A), each row/cell contains a single file name. The csv file has no header.
Something like this -
6_2021-05-10_02-00-36.mp4
6_2021-05-10_05-04-01.mp4
6_2021-05-10_05-28-59.mp4
6_2021-05-10_05-35-05.mp4
6_2021-05-10_05-35-34.mp4
6_2021-05-10_05-39-36.mp4
6_2021-05-10_05-39-41.mp4
6_2021-05-10_05-39-52.mp4
The number of rows in this csv file is variable.
I need to add a URL to the beginning of the text in each cell, such that, a valid URL is created - and the resulting csv content looks exactly like this:
https:\\www.url.com\6_2021-05-10_02-00-36.mp4
https:\\www.url.com\6_2021-05-10_05-04-01.mp4
https:\\www.url.com\6_2021-05-10_05-28-59.mp4
https:\\www.url.com\6_2021-05-10_05-35-05.mp4
https:\\www.url.com\6_2021-05-10_05-35-34.mp4
https:\\www.url.com\6_2021-05-10_05-39-36.mp4
https:\\www.url.com\6_2021-05-10_05-39-41.mp4
https:\\www.url.com\6_2021-05-10_05-39-52.mp4
So, this is what I've come up with, but it does not work.....
Param($File)
$csvObjects = C:\_TEMP\file_list_names.csv $file
$NewCSVObject = "https:\\www.url.com\"
foreach ($item in $csvObjects)
{
$item = ($NewCSVObject += $item)
}
$csvObjects | export-csv "C:\_TEMP\file_list_names_output.csv" -noType
But it's not working, and my PowerShell skills are not so sharp.
I'd be so very grateful for some assistance on this.
Thanks in advance-

Answer 1

just concat with what you want:
$file2 ="C:\fic2.csv"
$x = Get-Content $file2
for($i=0; $i -lt $x.Count; $i++){
$x[$i] = "https:\\www.url.com\" + $x[$i]
}
$x

Answer 2

Technically speaking your inputfile can serve as csv, but because it contains only one column of data and has no headers, you can treat it best with Get-Content instead of using Import-Csv
Here's two alternatives for you to try.
$result = foreach ($fileName in (Get-Content -Path 'C:\_TEMP\file_list_names.csv')) {
'https:\\www.url.com\{0}' -f $fileName
}
# next save the file
$result | Set-Content -Path 'C:\_TEMP\file_urls.csv'
OR something like:
Get-Content -Path 'C:\_TEMP\file_list_names.csv' | ForEach-Object {
"https:\\www.url.com\$_"
} | Set-Content -Path 'C:\_TEMP\file_urls.csv'
Urls usually use forward slashes / not backslashes \.. I left these in, so you can replace them yourself if needed

Answer 3

With the help of Frenchy.... the complete answer is.... (URL changed for security reasons obviously)
#opens list of file names
$file2 ="C:\_TEMP\file_list_names.csv"
$x = Get-Content $file2
#appends URl to beginning of file name list
for($i=0; $i -lt $x.Count; $i++){
$x[$i] = "https://bizops-my.sharepoint.com/:f:/g/personal/gpowell_bizops_onmicrosoft_com/Ei4lFpZHTe=Jkq1fZ\" + $x[$i]
}
$x
#remove all files in target directory prior to saving new list
get-childitem -path C:\_TEMP\file_list_names_url.csv | remove-item
Add-Content -Path C:\_TEMP\file_list_names_url.csv -Value $x
