Is this from a sub-process (eg launched with exec)? If so, use open with a
pipe:

replace

exec some command line

with

pack [text .t] -expand yes -fill both
set fp [open "|some command line" r]
fileevent readable $fp "writeToText $fp .t"

proc writeToText {chan text} {
if {[gets $chan line] < 0} {
catch {close $chan}
} else {
$text insert end "$line\n"
}
}
