title: Change perforce workspace view map from commandline
body: <p>I have searched the internet and the perforce help pages, but couldn't find a solution to my problem.</p>
  
  <p>In a script, so on the commandline, I want to change my workspace view map. For example:</p>
  
  <p>//depot/some/branch/myfolder/mysubfolder/... /home/myuser/perforce/branch/myfolder/myworkspace/...
  to
  //depot/some/branch/... /home/myuser/perforce/branch/...</p>
