How to excecute a script with TCL

[fabien]

Hello,

I am new Tcl user and I am trying to execute an AWK or Cshell script from within a Tcl script.

I have tried:
set test = Eval[$scriptname < $inputdataname]

but this does not work. How can I store the result of scriptname < inputdataname (will output some text) into test?

THanks for your help.

hi fabien..

Couple of ways you can possibly do this:
One way is via process pipes, and open the process
as you would a file or socket if that is called for.

set XX [open &quot;| awk -F scriptname&quot;]

to just retrieve the output of the script run:

set XX [exec scriptname]
This is probably what you are looking for .

To just execute the script form within the tclsh..
either exec scriptname as above, or system scriptname
will work.

thanks a lot marsd, the second solution worked fine!
