STSADM Commands and Power Shell Commands  for Deploying ,Installing activating feature


stsadm –o addsolution –filename “D:\Deploy\MySharePointSolution.wsp“
We used the following command to deploy the solution once installed to a specific web application:
stsadm –o deploysolution –name MySharePointSolution.wsp –url http://myspwebappp –allowgacdeployment –immediate
If we would upgrade an existing solution, we would use the following:
stsadm –o upgradesolution –name MySharePointSolution.wsp –filename “D:\Deploy\MySharePointSolution.wsp” -immediate
And finally, we used the following commands to retract and delete a specific solution from the web application:
stsadm –o retractsolution –name MySharePointSolution.wsp –url http://myspwebapp –immediate
stsadm –o deletesolution –name MySharePointSolution.wsp
Now, let us see how we could do above operations with PowerShell. For this, we use the following PowerShell commands:
Add-SPSolution “D:\Deploy\MySharePointSolution.wsp“
Install-SPSolution –Identity MySharePointSolution.wsp –WebApplication http://myspwebapp –GACDeployment
If you would like to add the solution as sandboxed, you would use the Install-SPUserSolution command instead. To upgrade a solution, we specify which solution is to be updated and with which new solution file:
Update-SPSolution –Identity MySharePointSolution.wsp –LiteralPath “D:\Deploy\MySharePointSolution.wsp” –GacDeployment
To retract and remove a solution, we use the following commands:
Uninstall-SPSolution –Identity MySharePointSolution.wsp –WebApplication http://myspwebapp
Remove-SPSolution–Identity MySharePointSolution.wsp

Working with features

Similarly, commands exist for working with features. The stsadm equivalents:
stsadm –o activatefeature –name MyFeatureName –url http://myspwebapp
stsadm –o deactivatefeature –name MyFeatureName –url http://myspwebapp
Needless to say, there are easy equivalents in PowerShell:
Enable-SPFeature –Identity MyFeatureNameOrGuid –url http://myspwebapp
Disable-SPFeature –Identity MyFeatureNameOrGuid –url http://myspwebapp
