Minding Path Inputs in a Cmdlet

When I was a Monad neophyte, I was asked to write a Cmdlet taking a file path as a parameter. A big mistake I made was not keeping in mind that in Monad the FileSystem provider was just one of the many providers.

Single Shell vs Custom Shell

With Monad Beta 3 release, we've introduced the concept of the "single shell". What is a single shell? "One shell to rule them all ... and in the darkness..." (Sorry I can't stop saying that quote everytime I hear "single shell"!) Well rather than having to create a separate executable/shell to host your own cmdlets/providers, you can now ...

Using Monad for logon scripts

In case you were wondering, yes, you can use Monad for your logon scripts.  You can't just assign a .MSH file as a logon script however, since only file types with file associations work as logon scripts.  Monad installation doesn't create a file association ".MSH -> msh.exe -command %1" for security reasons.  The best way...
