[REBOL] Re: rebol to bash?

Hi Tom,
It's exactly this issue that eroded my faith in rebol. Every other
language i've come across allows me to make use of the amazing variety of
command-line tools on UNIX such as ls, grep, locate etc and store the
stdout in a variable for further processing. REBOL/Command lets you do
this but only at a price of US$300.
This is the primary reason why I am trading in REBOL for tcl 'tickle'.
This language has a similar structure to rebol but can access external
commands. For example:
set newline = "\n"
puts "The following users are logged in $newline [exec users]"
This is very similar to rebol syntax except you can merge strings with
variables more easily than using 'print 'form 'rejoin combinations. Tcl
also understands blocks in a similar way to rebol:
REBOL [] ; a REBOL script
foreach number [1 2 3] [
switch :number [
1 [print "One"]
2 [print "Two"]
3 [print "Three"]
]
]
# A tcl script
foreach number {1 2 3} {
switch $number {
1 {puts "one";}
2 {puts "two";}
3 {puts "three";}
}
}
Tcl/Tk also has an excellent windowing system with much clearer syntax
than the 'faces' of REBOL/View.
But best of all Tcl doesn't time out - ever - which in REBOL is driving me
batsh!t. I'm sure many will agree with that last statement if nothing
else.
REBOL is a fantasic language and I love the syntax but problems with
controlling ports, using parse and particularly interacting with external
applications makes it pretty useless for controlling UNIX servers, which
is basically what I need. Fortunaetly I can still take advantage of some
of REBOL's better features by calling it from Tcl scripts like this:
exec rebol --do send [sales--rebol--com] "Sorry...";
Like they say Tom, "The right tools for the right job!"
