ssh: Execute a command on another machine

Description

This function composes an ssh (Secure SHell) command to run something on another machine and invokes it via system(). It uses the plink program (part of the open-source PuTTY suite) to send a command to a remote computer via the ssh protocol.

Usage

ssh(command, host = getOption("remoteHost"), user. = user(),
    password = "", wait = F, ...)

Arguments

command

command to be executed on the remote machine

host

hostname of the remote machine

user.

username on the remote machine

password

password on the remote machine. If missing, the function will prompt for it.

wait

if TRUE, return only after command has finished running on the remote system. If FALSE (the default), return immediately after sending command to the remote system.

...

additional arguments passed to system

Value

• The return value is whatever the system() function returns. If ... includes intern = T, this will be whatever the ssh or plink returned.

Examples

ssh("uname -a", host = "localhost")
