How to write ONE line of command that scp all the sub-directories in a directory to a remote machine

something like:

scp -r all_directories_in_current_directory fenix@xxxxx:~/data

anyone can give me a clue?

scp -r * fenix@xxxxx:~/data 

If you only want the directories, not the files in the current directory:

scp -r */ fenix@xxxxx:~/data 

This will not copy hidded(names startingwith a . ) directories.

Use rsync rather thsn scp, e.g.

$ rsync -av ./ fenix@xxxxx:data/

Do NFS mount, and do cp -avx.
