qvm-run fails in Whonix VMs
[user@fedora]$ qvm-run Usage: /usr/bin/qvm-run vmname command arguments Executes a command in another VM using the qubes.VMShell RPC service. The arguments are joined with spaces and passed to "bash -c". Standard input and output are connected to the command. Unlike qvm-run in Dom0, this tool does not propagate standard error or exit codes, nor does it offer protection against the remote VM messing with your terminal if standard output is your terminal. You can use $dispvm or --dispvm instead of vmname to start a new DisposableVM.
In any Whonix VM (template, proxy, app):
user@host:/usr/bin$ qvm-run /usr/bin/qvm-run: 23: /usr/bin/qvm-run: Syntax error: "(" unexpected
Both /usr/bin/qvm-run scripts are identical.
