Is there any easy way to do this?
input: 123215-85_01_test
expected output: 01_test
Another example
input: 12154_02_test
expected output: 02_test
There will be always string "test", but different numbering before
for example this code..
$path = "c:\tmp\*.sql"
get-childitem $path | forEach-object {
$name = $_.Name
$result = $name -replace "","" # I don't know how write this regex..
$extension = $_.Extension
$newName = $prefix+"_"+ $result -f, $extension
Rename-Item -Path $_.FullName -NewName $newName
}
