<lynx> btw, in *ksh you do this: find "$@" -print0 |& while read -pd ''; do …
<igli> ah does that keep the while in fg?
<lynx> yes
<igli> sweet
<lynx> it's actually two lines
<lynx> you newline after find "$@" -print0 |&
<lynx> it's conceptually like &
<lynx> except stdio of find is connected to fd 'p'
<lynx> you can even do things like exec 3>&p
<igli> ah ok
<lynx> then echo >&3 to communicate to the subprocess
<lynx> later exec 3>&- to close its stdin
<igli> heh
<lynx> stderr is shared
<lynx> well if you need that. this is how I remote-controlled SQL*plus from ksh
<lynx> just started the sqlplus at begin of script, then read and wrote to when needed
