The only problem with Replace-Something name is:
WARNING: The names of some imported commands from the module 'Xxxx' include
unapproved verbs that might make them less discoverable. To find the commands
with unapproved verbs, run the Import-Module command again with the Verbose
parameter. For a list of approved verbs, type Get-Verb.
What is correct name for commandlet that will replace some content?
Get-Verb does not seem to have anything suitable.
How about ‘Set’. Like in Set-Content which implies replacing whatever is already there.
Or
Update(Data) orOut-Force (Data) if you writing a file.
