Add to Array of wildcards in Powershell - powershell

Question

I am new to powershell and looking to test something for a POC.
There are multiple files stored on the cloud inbox (File_1.txt, File_2.txt and so on).
I want to add these files using a wildcard to an array and then run some commands (specific to the cloud) for each file.
I cannot specify the -Path in the code as the files are located on cloud and I do not have the path.
The below code works:
$files = #("File_1.txt","File_2.txt","File_3.txt")
foreach ($file in $files) {
Run commands on cloud like...delete inbox/$file
}
However I cannot hard code the file names. I am looking to add file names using wildcard.
$files=#("File*.txt")
foreach ($file in $files) {
Run commands on cloud like...inbox/$file
}
But this does not work as in the log it is taking File*.txt as the name of the file.
Thanks in advance

Answer 1

You should use dir equivalent of PowerShell, Get-ChildItem (In fact dir and ls are aliases for the Cmdlet) to search files using wildcards:
$files = Get-ChildItem file*.txt
foreach($file in $files) {
DoSomeStuffWithFile $file
}
Get-ChildItem returns FileInfo objects. If you want to use the filename String in the loop, you should refer to the Name property of the object:
DoSomeStuffWithFileName $file.Name

You can easily update the file number using string interpolation. Here is a basic example of how this might work:
1 .. 10 |
ForEach-Object {
"hello" | Out-File -Path "File_$_.txt"
}
Here we generate an array of the numbers from 1 to 10 (using the range operator ..), then this is piped to our command (and hence placed in the $_ variable). As each number comes through, the path is constructed with the current value of $_, so you get File_1.txt, File_2.txt, etc.
You can use other looping techniques, but the key is that you can build the filename/path on-the-fly by having PowerShell replace the variables for you.
