I will assume this is for SharePoint 2007. There are two STSADM commands that need to be run (SharePoint 2010 should use Powershell...STSADM is only there for backwards compatibility).
Add the solution:
stsadm -o addsolution -filename C:\H\H\H.wsp
Deploy the solution:
The parameters for deploying your solution package are largely going to depend on what is in the solution and what needs to be deployed.
A simple global deployment may look something like this:
stsadm -o deploysolution -name H.wsp -immediate
For a deployment targeted to a specific web application in your farm and with assemblies being deployed to the GAC it may look something like this:
stsadm -o deploysolution -name H.wsp -url http://mydomain.com -allowgacdeployment -immediate
