Leo Simons fec14cf04c Use -f argument to rm to force-remove files.
When using pty=true, removing files using sudo may request confirmation,
which will hang the connection.

Similarly, sometimes assumptions about file existence may be wrong and
in those cases it seems better to continue on as long as the file does
not exist, so -f makes sense there, too.
