While the previous answers are technically correct, you should also consider using rsync instead. rsync compares the data on the sending and receiving sides with a diff mechanism so it doesn't have to resend data that was already previously sent.

If you are going to copy something to a remote machine more than once, use rsync. Actually, it's good to use rsync every time because it has more controls for things like copying file permissions and ownership and excluding certain files or directories. In general:

$ rsync -av /local/dir/ server:/remote/dir/

will synchronize a local directory with a remote directory. If you run it a second time and the contents of the local directory haven't changed, no data will be transferred - much more efficient than running scp and copying everything every time.

Also, rsync allows you to recover from interrupted transfers very easily, unlike scp.

Finally, modern versions of rsync by default run over ssh, so if scp is already working, rsync should pretty much be a drop-in replacement.

That is what the -r option is for. :)

See the scp man page for more info if needed.

Recursive Copy Option '-r' (lower case)

scp -r

Which I confuse with the regular local recursive copy option '-R' (upper case)

cp -R

The best way is to use rsync over SSH

rsync -a -essh /source/ user@dest-server:/dest/

rsync -a -essh user@source-server:/source/ /dest/

My favorites options are -Pazvessh --delete :

• -a : archive mode (include a lot of default common options, including preserving symlinks)


• -z : compress


• -v : verbose : show files


• -P : show progess as files done/remaining files


• -e ssh : do rsync in ssh protocol


• --delete : delete files in the destination that are not anymore in the source

After looking for the recursive copy flag, and successfully used it thanks to this post, I would like to post just a suggestion.

If the case is that you are copying (recursively) a directory. Maybe if the files are sent compressed you could save time in the transfer

What I did in the end was:

local$ tar -czvf local.tar.gz directory/
local$ scp local.tar.gz user@remote:/directory
ssh user@remote
remote$ tar -xzvf local.tar.gz

Hope this helps

You can recursively copy a directory into a compressed archive with this simple command:

ssh -p 22 user@address-to-copy-from.com 'cd /parent/directory && tar zcvf - directory_to_copy' > /destination/on/your/machine/archive_name.tgz

For example, to copy contents of /var/log from domain.com to ~/logs.tgz you run:

ssh -p 22 user@domain.com 'cd /var && tar zcvf - log' > ~/logs.tgz

You can also extract files on target system by using pipes. This command will copy contents of /var/log at domain.com to ~/destination/log on your system:

ssh -p 22 user@domain.com 'cd /var && tar zcvf - log' | tar xzf - -C ~/destination

Though to mirror a directory, you probably should use rsync...

If you prefer to pass the user's password as a parameter rather than inputting it interactively, you can use sshpass (sudo apt-get install -y sshpass).

Example:

sshpass -p 'remote_password' scp -rp /src/folder myremoteusername@122.10.12.123:/dest/folder

You can use -r option with scp command to copy directories recursively on any system. If you need anything else refer scp command tutorial. -r option stands for recursive operation in most of the Linux commands.
