What Is 'tsshbatch'?
--------------------

'tsshbatch' is a server automation tool to enable you to issue commands
to many servers without having to log into each one separately. When
writing scripts, this overcomes the 'ssh' limitation of not being able to
specify the password on the command line.

'tsshbatch' also understands basic 'sudo' syntax and can be used
to access a server, 'sudo' a command, and then exit.

'tsshbatch' thus allows you to write complex, hands-off scripts that--

issue commands to many servers without the tedium of manual login and
'sudo' promotion. System administrators, especially, will find this
helpful when working in large server farms.

'tsshbatch' is written in Python and requires the 'paramiko library.
It has been tested on various Linux and FreeBSD variants.

'tsshbatch' is written in Python and requires the 'paramiko library.
It has been tested on various Linux and FreeBSD variants as well
as cygwin on MS-Windows.
This option also overrides any previous
request for key exchange authentication.

- A new option, -S, forces prompting for the sudo password, with the
default being any previously provided password (interactive or -p).
This allows you to use one password to authenticate to the system
and a different one to do sudo promotion.

- Two new options, -G and -P, support file transfer GETs and PUTs
respectively from the selected hosts.

- A new option, -f cmdfile, allows multiple commands stored
in the file to be run on each of the selected hosts. This
allows for considerably more complex operations than the
single command string at the end of the command line supported
in previous versions.

- A new option, -y, turns on 'noisy' reporting and produces
context information (hostname, output stream, and command)
for every line of output. This makes the output more useful
when filtered through something like 'grep'.

- There is a new options, -t, to turn on "test mode" which
will show what would be done, but will not actually do it.
This mode also displays useful diagnostic information
about the command line, variable defintions, file tranfer
requests, and so on.

- The new -x option is used to negate a prior -t and thereby
force execution of the requested file transfers and/or
commands.

- Both cmdfiles and hostlistfiles now support freeform whitespace
and commenting via the "#" character.

- Both cmdfiles and hostlistfiles now support including other
files via the .include directive. Circular include detection
is also implemented.

- Both cmdfiles and hostlistfiles can contain variable
definitions that are literally replaced in any following
text.
