What O/S, what's in the CSV?pardon...
Single line in PowerShell - I am assuming its in a subfolder of C:\ called MyData and you want to sort on Name columnwindows 7, it's just going to be basic text. Two columns, first column with a number, and the second column with a name.
PS C:\> $mycsv | Get-Member
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
