[clue-tech] Help using 'rsync'?

[Adrian F. Nagle, IV]

Folks,

I found this command for backups.  It appears to do what I want, that is copy the contents of one USB drive to another USB drive:
sudo rsync -av --progress --delete --log-file=/home/addy/Desktop/$(date+%Y%m%d_rsync.log /media/nagle_ext1 /media/nagle_ext1_bk

Both the directories are mounted.  When I run the command, I get a new lines with ">", a sub shell?  It does not appear to do anything and just hangs at the new prompt.  I'm not sure what to expect with the --progress option.

Adrian
