Are there any command line SSH clients available for rooted Android phones? I of course have ConnectBot, but I'm looking for something I can script. 

Edit: To clarify here, I'm not interested in running scripts from a terminal. What I want to do is run an SSH command in an automated/scheduled manner. Tasker and Locale Execute are the equivalent of cron, all I need is the 'ssh' command to run from the script.
Since my original question was about an ssh binary, and there is an answer for that, I'll accept that answer. However, there is another way to do what I wanted to do, kinda, that might be interesting to someone some day. 

Tasker + ConnectBot can be used to execute arbitrary remote (or local, I guess, but Locale Execute is better for that) commands on a schedule. 

Step 1: Set up your connection in ConnectBot. 


You can have duplicate connections in ConnectBot as long as they have different aliases. You have to rename one first (away from user@host) in order to create the second. Long Press and select "Edit Host" to perform these changes. 
You probably want to set up an ssh key without a password so that you can use this for automation. 
Once the connection actually works, you can use "Post-login automation" to add the remote commands you would like to run. Make sure there is a blank line at the end so that enter is sent after your last command. Use enter or ; to separate commands. I suggest using something like "echo hello" as a test until you are sure things are working, and "exit" at the end if you don't want to leave the connection open. 
Test this in isolation. 


Step 2: Create a Tasker Task to call connectbot. 


Create a new Task in Tasker. 
Add an Action. From Misc, select "Action Intent"
The fields are: 

Action: android.intent.action.VIEW
Cat: Default
Data: ssh url, in the form of "ssh://user@host/#alias" (without the quotes). The alias, user and host here must match the alias you set up in Step 1. 
Target: Activity
Click Test. Connectbot should open and your commands should execute on the remote host. 



Step 3: Use this Task in Tasker however you would normally.
