The platform-testing methods in OSProcess are:
 
   #isUnix
   #isUnixMac
   #isNonUnixMac
   #isWindows
   #isOS2
   #isRiscOS

These methods cover enough of the known variations of "platform name"
to serve the needs of the OSProcess/CommandShell packages.

I'm sure you will also enjoy reading this:
 
OSProcess class>>platformName
   "After Squeak version 3.6, #platformName was moved to SmalltalkImage Some
   versions of Pharo move this to OSPlatform and issue deprecation warnings
   about the other usages. The original idiom (Squeak 3.6 and earlier) is the sensible
   default, but here we attempt to support other implementations if the sensible
   default is not available."

   "OSProcess platformName"

   (Smalltalk respondsTo: #platformName)
      ifTrue: [^ Smalltalk platformName].
   self isPharo3AndLater
      ifTrue: [ ^ (Smalltalk perform: #os) name ].
   ^ (((Smalltalk hasClassNamed: #OSPlatform)
         and: [(Smalltalk at: #OSPlatform)
               respondsTo: #platformName])
      ifTrue: [Smalltalk at: #OSPlatform]
      ifFalse: [((Smalltalk classNamed: 'SmalltalkImage')
            ifNil: [^ Smalltalk osVersion]) current]) platformName
