Tcl (Tool Command Language) is a very simple, open-source-licensed programming language. Tcl provides basic language features such as variables, procedures, and control, and it runs on almost any modern OS, such as Unix (Linux and non-Linux), MacOS, Windows 95/98/NT/2000/XP/…, PDA systems, and many more. But the key feature of Tcl is its extensibility.

And unlike any other scripting languages, just -v option won’t give you the version of your Tcl, there is a separate variable defined for that, tcl_version. So, just say puts $tcl_version to know your Tcl version.

There is a good Wiki for Tcl users, give a try:
