syncronizing with unison on ubuntu

Which manual do you refer to? I think that the tutorial is quite clear...

Anyway, I use Unison to sync all my machines. What I do is:

1. Create a profile in ~/.unison, myprofile.prf, like this:

   label = my shiny new profile
   root = /home/romano/
   root = ssh://romano@remotehost//home/romano/
   
   path = education
   path = research
   ...
   

   (the path elements limits the subdirectories to be synced; i do not want all directories in my home to be synced by this profile, your usage can vary; if you use no path you'll duplicate everything --- be careful with hidden files though)

2. Then I check that the thing works ok using the graphical interface unison-gtk --- from there you can check if the operation is going to be ok):

3. Once you are confident that the sync will not eat your data for breakfast, you can use on the command line

   unison -auto -batch myprofile
