How do I execute a script on remote server called server2.example.com from my PC? How to run a shell/python/perl script on remote Unix-like systems?

You can use the ssh client which is a part of most *BSD/Linux/OS X/Linux distros/Unix-like oses. If you are on MS-Windows operating systems you need to download and use Putty client.

ssh command line syntax

The basic syntax is as follows:

ssh user@server-name-here /path/to/script
ssh user@server-name-here /path/to/script arg1 arg2 arg3

OR

ssh user@server-name-here /path/to/command
ssh user@server-name-here /path/to/command arg1 arg2

Examples

Open the Terminal. To run a script called /root/scripts/backup.sh on remote UNIX or Linux server called server1.cyberciti.biz, enter:

ssh root@server1.cyberciti.biz /root/scripts/backup.sh

You can pass command line arguments too:

ssh root@server1.cyberciti.biz /scripts/job.init --job=sync --type=aws --force=true

You can execute the date command as follows on remote server:

ssh user@server2.example.com date

You may need to specify full script path. In this example, run /root/backup.sh script as follows:

ssh user@server2.example.com /root/backup.sh

To avoid password prompt set password less ssh keys or use tool such as keychain - a manager for ssh-agent, typically run from ~/.bash_profile.

jay – you could try “passwordless ssh”. There’s stuff on Google about that.
