Thanks, that's exactly what I need. My idea is to use this inside
sam itself with '|', so that I can easily edit small parts of big
files.

Here is my working version for linux. The only important change is
that I had to replace your use of $tty to a loop that uses 'fuser'
to find the terminal owned by $pid.

Best,
Maur�cio

#!/home/mauricio/plan9/bin/9 rc

file = $HOME ^ '/tmp/eec-' ^ $pid

cat > $file
pts = `{for (i in /dev/pts/*)
   achou = `{fuser $i >[2]/dev/null | grep $pid} {
     if (test -n $"achou) echo $i}}

#Note: 's' is a script that translates to sam.
s $file <[0]$pts >[1]$pts

cat $file

rm $file
