I have no idea what created this file - I guess a terrible shell script.
It is called '.env'$'\r'
I have tried various versions of rm, and the technique of opening the direcory with vim ./, selecting the file, and Shift-D to delete.
This didn't work, failing with a
**warning** (netrw) delete(/root/squawker/.env) failed!
NetrwMessage [RO]
"NetrwMessage" --No lines in buffer--
How can I delete this pesky file?
This is on Ubuntu 20.04
