Via command line, can someone suggest ways to change directory (cd) to a SharePoint link (pointed via a xyz.lnk link)?
You can map a network drive to a WebDAV folder and use that drive to copy files (or whatever you would like to do).
net use z: https://<url>
cd z:
dir
I would use PowerShell to parse out the url from the .lnk file (if that is neccessary).
