If you're new to Tcl and would like to start using it on Cisco IOS, here's what worked for me:
- I've downloaded the ActiveTcl from ActiveState. It's always good to have development environment on your workstation.
- The documentation that comes with ActiveTcl is quite cryptic, but once you know what you're looking for, it's OK.
- To get to the "I know what I'm looking for" stage, I've used Tcl/Tk: A Developer's Guide.
If you know better beginner books/sources, let us all know.
You can find more Tclsh-related information in the Tclsh on Cisco IOS tutorial. Sample Tclsh scripts are available in the Tclsh script library. If you need expert help in planning, developing or deploying Tclsh scripts in your network, contact the author.
