Introduction

Each executable jar supports a "learning mode" that observes an interactive SSH session and records prompts and responses. This makes it easy to create simple scripts or generate the script skeleton for more complex ones. The generated script is written in the favored scripting language of the jar. For example, if the jar is enchanter-python-VERSION.jar, the script will be written in Python.

Details

Learning mode can be invoked from the command line by passing special arguments:

Short	Long	Required	Description
l	learn	yes	Enables learning mode
h	host	no	The server host
p	port	no	The server port
u	username	no	The user name on the server
P	password	no	The password for the server account
N/A	prompt-size	no	The number of characters to capture for prompts

In learning mode, the script name, passed as the last argument, is interpreted as the name of the file to write the generated script.

The learning mode works by keeping track of the last 10 (configurable with the prompt-size argument) characters throughout the session. When the user types characters that end in a newline, the last 10 characters (or as many as occurred after the last newline) are interpreted as the prompt and the user's characters as the response. This means control codes like ^C won't be captured, or basically any input that doesn't end in a new line.

Examples

This connects to myserver.com as myuser and generates a script named myscript.py

java -jar enchanter-python-VERSION.jar -l -h myserver.com -u myuser myscript.py
