How to remove words and characters from a multivalued filed

[MeMilo09]

Hello All, 

How can I remove words and characters from a multivalued field without using REX?

I have a filed named OS

OS:
Windows-2016
Windows-2010


How can I take out everything that comes in before the hyphen and just end up with the below?

OS:
2016
2010

Try mvmap and replace.

| makeresults 
| eval OS="Windows-2016
Windows-2010" 
| eval OS=mvmap(OS,replace(OS,"Windows-",""))

@richgalloway Your example doesn't create a mv-field but your solution works when the field is mv.

| makeresults 
| eval OS=split("Windows-2016
Windows-2010" ,"
")
| eval OS=mvmap(OS,replace(OS,"Windows-",""))

Pretty close, just used mvindex instead. Thanks 

| eval OS_Name=split(OSName,"-"), Env=mvindex(OS_Name, 1)
