I'm afraid I don't understand the perceived problem. What is meant there. If I have the following script (which is a bit more general than it needs to be for this, as it was a modified version of another script I used for testing just how shells process read(1)): I= case "" in -i*) I=; shift;; -I) I=unset; shift;; esac printf %s\n "" | { case "" in unset) unset IFS;; *) IFS="";; esac read -r var rest && printf %s\n var="[unset] rest=[unset]" } and I call it /tmp/r2 and run it as /usr/pkg/bin/bash /tmp/r2 -i: line: then every shell I tested produces: var=[line] rest=[] as the result. I'm not sure what different you'd be expecting there. Here "every shell" includes zsh, even when not in --emulate sh mode, and NetBSD's crappy ancient pkksh implementation. That is, apart from ksh88, which I don't have, just about every currently used Bourne shell derivative which is still in active use.
