Or you can copy all your scripts on one of your local workstation
(assuming your workstation is a *nix flavor machine with open ssh client
installed) and then execute them remotely as:

cat script.sh | ssh root@target-host

and if there are multiple machines then you can also do:

for host in 'host 1 host 2 host3';do cat script.sh | ssh user@$host;done

One thing to keep in mind though, since the commands will actually be
executed on the remote hosts, if the script(s) are dependent on anything
then that should be present on target server.
