Perforce: Delete a client/workspace even if it does not exist anymore

So the user formatted/lost/whatever their computer and maybe even had opened files there?
Grab your admin account:

1. p4 client WORKSPACE
   Delete the line starting with "Host:", to remove host restriction from that client workspace.
2. p4 -u USER -c WORKSPACE revert -k -a
   Reverts all (no file glob specified) unchanged (-a) open files in that workspace (-c), and doesn't sync anything (-k).
3. p4 client -f -d WORKSPACE
   Deletes (-d) the workspace, forced (-f).

Extras:

• List user's client workspaces:
  p4 clients -u USER
• Remove all managed files (just files! directory is just metadata in perforce) from the current workspace:
  p4 sync //...#none
  Then delete the directories manually -_-
• Explicitly set a server:
  p4 -p perforce-otherone:1666 clients -u USER
• (Moar to come)
