/**
* put [-afPpr] local-path [remote-path] Upload local-path and store it on the
* remote machine. If the remote path name is not specified, it is given the
* same name it has on the local machine. local-path may contain glob(7) charac‐
* ters and may match multiple files. If it does and remote-path is specified,
* then remote-path must specify a directory.
*
* If the -a flag is specified, then attempt to resume partial transfers of
* existing files. Note that resumption assumes that any partial copy of the
* remote file matches the local copy. If the local file contents differ from
* the remote local copy then the resultant file is likely to be corrupt.
*
* If the -f flag is specified, then a request will be sent to the server to
* call fsync(2) after the file has been transferred. Note that this is only
* supported by servers that implement the "[email protected]" extension.
*
* If either the -P or -p flag is specified, then full file permis‐ sions and
* access times are copied too.
*
* If the -r flag is specified then directories will be copied recursively. Note
* that sftp does not follow symbolic links when performing recursive transfers.
