Since it appears from your post that both files are on the same remote host you could use 'rsh host diff file1 file2'.

The diff command is not equipped to handle files residing on remote hosts. There are a few ways that you could go about this. All involve getting the remote file to the local host, or sending the local file to the remote host.

This is how you can do it using rsh:

Code:

rsh -l username remote_host cat full_path_to_remote_file > /tmp/remote_file
diff /tmp/remote_file local_file
### take further action depending on the output?

This is how you can do it using ssh:

Code:

ssh username@remote_host cat full_path_to_remote_file > /tmp/remote_file
diff /tmp/remote_file local_file
### take further action depending on the output?

Note that the '>' will create a file named /tmp/remote_file on the local system. To create remote files using either rsh or ssh, you have to escape the '>' as '\>'
