Writes a local file — or stdin, with - — to a remote path.
bonya fs write [sandbox] <path> <local-file-or-->
Argument order is remote path, then local source — the opposite order from upload. write exists mainly for piping stdin straight to a remote file; upload exists for local-file-to-remote-file with the more intuitive source-then-destination order.
bonya fs write web /workspace/notes.txt ./notes.txt
echo 'hello' | bonya fs write web /workspace/hello.txt -
