hey,

i've a command which works nicely on the commandline through:
Code:
go -c 'open -e "do $fistpath $secondpath" remotemachine'


i've tried this to script into my tcl, to use it in my channel every way possible to me, but it ain't work... ;-/

Code:
set res [catch {eval exec "go -c 'open -e \"do $fistpath $secondpath\" remotemachine'"}]



i tried to escape the " and to {"} them, nothing helps...


any ideas what's wrong?

every help is greatly appreciated.. thanks

do not enclose [exec]'s args in double quotes and read Script Security thread in the FAQ forum
