The list of all the arguments passed to the process hosting your Tcl interpreter can be accessed using the global variable argv, which you can iterate over and inspect.

Special packages implementing ready-made solutions for "declarative" parsing of command-line arguments exist, with cmdline being one example. Also search the wiki for alternatives.

The argc global can also be useful occasionally, but it's really just the same as llength $argv…

I think, you need the cmdline package from tcllib.

Documentation is here
