If you read the document linked by DukeNuke2 in the first reply to your question, you will see the command to run is packagemanager You then need to read the rest of the document to decide what else you need to include to get it to do what you want as the tool can do more than one thing and needs to be told what you really want it to do and with what input.
What have you tried to do and what errors did you get? If it rejects your command, it will not do anything dangerous.
Please post the commands and output/errors in CODE tags to make it easy to read.
You need to show some effort so we can understand what skills you have, where you are getting stuck and what assistance you need. We are not a free support and/or coding service, nor do we take subscription fees. We are rewarded by the knowledge we gain and the satisfaction from helping others, but that means the members need to make a genuine effort to solve the problems they have and show us their efforts with output, errors and other diagnostics so we are in the best place to steer you.
Kind regards,
Robin
