The tclsh is the command to enable scripting.
Watch the spaces between ops!

tclsh is in fact a lot more powerful than it is skimmed in the papers
that are available. If you have a progammer side in you :-)

You can program "user commands" to, e.g., test is a given route is
present in a given router and only barf if it is not.
Iterating this over all your routers can give, in seconds, messages like:

144.18.23.0/24 not there at R3
144.18.23.0/24 not there at R4

that could be very helpful IF your lab has strong routing problems.
On the other side, building the required framework can take you 10 to 15
minutes which could be more than you are willing to dedicate to have
this tool in place. If you are not programming oriented, it could
actually create more problems that those that it should help you fight!

HTH.
