replace all members in the distribution list with the member only input csv

Sorry if this is a repeat as I didn't see my question listed.  I have this one liner -
Update-DistributionGroupMember -Identity -Members
to replace all members in the distribution list with the member only
Looking for some help in creating a script that will read in the other 385 distrib groups and associated member to replace from a csv file.

Thanks but is there a way to input the whole csv file in with all the distrib groups in - not just the -Identity of - but all the list?  like read in the whole file?

YOu seem to already have it in control.
Create a folder named Temp on your C:drive
1.  List all the members of the by their email addresses in a .csv with a header named Users
save it as c:\temp\contitechusers.csv



Import-csv 'c:\temp\contitechusers.csv' | %{Update-DistributionGroupMember -Identity -member $_.Users -Confirm:$False}
