TclTK help - how to puts the contents of a text widget

[jtnelson at genuity.net (Jason Nelson)]

In a quick cut and past I cut of  the file following the shell redirect
">".  Here is some working code (just change the path the wish):  
The "exec" command in tcl basically escapes wish to run shell commands.
This code puts the contents of a variable in a file allowing to you "save"
it.  I'm not sure if this what you are trying to do, Christoph, but hope
this is helpful.   Note ">>" will append ">" will overwrite existing files.

#!/usr/local/bin/wish -f

frame .middle -relief flat -borderwidth 2
label .middle.text -text "Paste Logs here"
entry .middle.elogs -relief sunken -width 60 -textvariable logs 
pack  .middle.text -side top
pack  .middle.elogs -side left
pack  .middle 

frame  .bottom -relief flat -borderwidth 2
button .bottom.b1 -text "Examine logs" 
pack .bottom.b1 -side left -padx 1m -pady 1m
pack .bottom.b2 -side left -padx 1m -pady 1m
pack .bottom

bind .bottom.b1 <Button-1> {
        exec echo "$logs" > /tmp/tcl.out
        exit
}
