Rename file using a hash table

Question

I have the following hash table.

$m = @{
    "AAA" = "XX";
    "BBB" = "YY";
    "CCC" = "ZZ";
    ....
}

I want to rename the files which names started with "AAA" to "XX....", "BBB" to "YY....", etc. For example, "AAA1234.txt" will be renamed to "XX1234.txt".

How to do it in Powershell?

Answer 1

Great..clearly explained.But this will rename the full folder name.. straight forward.

$m = @{"AA" = "XX"; "BB" = "YY"}
$files = Get-ChildItem -Path C:\test\ -Directory
$m.GetEnumerator() | %{Rename-Item "C:\test\$($_.Key)" -NewName "C:\test\$($_.value)" -Force
}
