Triggering a shell script on remote machine

I'm trying a automate a job, which involves, performing certain steps via shell script, do "SCP" of few files to remote machine and trigger a shell script on the remote machine.

Is there a way to achieve this task using shell script or any other scripts?

Thanks in advance, cherryhitech

run remote-script.sh on remote-host:

ssh user@remote-host ". remote-script.sh"

with key authentication:

ssh -i local/path/to/remote/key user@remote-host ". remote-script.sh"

If you plan to scp files and/or run commands via SSH in a script, make sure to set up SSH authentication using public keys. That way you won't be prompted to login, and the script will be much more 'script-like' (non interactive).

Here's how to do the above: http://www.debian-administration.org/article/SSH_with_authentication_key_instead_of_password

Once done, you can scp from a script - 

scp localfile remotehost:remotepath

Similarly you can run things on the remote host -

ssh remotehost uname -r

or

ssh remotehost /path/to/remote/script

You can always write a shell script. Try looking here for an introduction. As Paul R said, use scp to copy files to or from that server.

If by "automate" you mean "schedule to run automatically", check out cron. Running the script at midnight every night would mean running crontab -e and then adding the following line:

0 0 * * * /path_to_script

You can use ssh to run a remote script, e.g.

$ scp some_files remote_host:some_directory/
$ ssh remote_host my_script
