Yeah I am a newbie to tcl/tk and to this newsgroup also. I think tcl/tk is very
cool but unfortunatly I have had zero luck getting the hang of it! I have programmed
maily in korn shell in the past but have done Bourne, Csh, C, C++ I am trying to learn
Tcl/Tk from John K. Ousterhout's book. I am used to using all of the Unix Util's such
as nawk, sed, grep, sort. I often pipe a lot of these together and set a variable to
the result. This is a snap in Korn Shell but I can't do it in tcl yet I am really
stumped trying to get exec to do anything other than one simple command at a time.
Can someone suggest a good way for me to do those kinds of things with pipes? Is
exec the wrong command? When do I use eval? Also I am a bit confused what are the
differences in binding a command to a widget or using -command option on the widget?
Last but not least is there a way to display a scale that changes with a variables
state but does not give the using a slider button, or at least disables the slider?
Thanks alot, and I'll keep reading the book.
