Powershell equivalent of Bash Brace Expansion for generating lists/arrays

When writing a Bash script you can use brace expansion to quickly generate lists:

What is the simplest way to generate a similar list in Powershell? I can use the .. or , operators to generate an array, but how can I prefix the items with a static string literal?

PS C:\Users\gb> 1..5
1
2
3
4
5

PS C:\Users\gb> "test"+1..5
test1 2 3 4 5

PS C:\Users\gb> "test","dev","prod"
test
dev
prod

PS C:\Users\gb> "asdf"+"test","dev","prod"
asdftest dev prod
Solution 
  • PS C:\> "test","dev","prod" | % { "server-$_" }
server-test
server-dev
server-prod
PS C:\> 1..5 | % { "server{0:D2}" -f $_ }
server01
server02
server03
server04
server05
PS C:\> 1..5 | % { "192.168.0.$_" }
192.168.0.1
192.168.0.2
192.168.0.3
192.168.0.4
192.168.0.5

    Note that % is an alias for the ForEach-Object cmdlet.
