check if file exists on remote host with ssh

Question

I would like to check if a certain file exists on the remote host. I tried this:

$ if [ ssh user@localhost -p 19999 -e /home/user/Dropbox/path/Research_and_Devel         


        

Answer 1

This also works :

if ssh user@ip "[ -s /path/file_name ]" ;then 
  status=RECEIVED ; 
 else 
  status=MISSING ; 
 fi
