scpleads to frustration as a disconnect ruins your upload or download before it's done (and it usually happens just as it's past 90%, making you want to tear your hair out).
You can save yourself the anguish by using
rsyncinstead. It transfers files either individually, or it can copy entire directories. You can resume the transfer if you're disconnected. The following will copy the entire contents of the remote directory into
rsync -avP --rsh=ssh --bwlimit=25 email@example.com:/path/to/files/ /local/path/
When invoked this way,
sshto transfer files, and the options are archive mode (all symlinks and permissions are intact), verbosely, and with progress meter. You can replace the
/path/to/files/subdirectory name option with a single file if you want only that particular file.
bwlimitswitch is optional, as it limits the bandwidth usage (in kb/s) to the value specified. This is to make sure your download or upload doesn't saturate your connection. The
rsyncprogram needs to be on both source and destination for this to work.
