I understand why IFS needs to be reset. But unset $IFS
does not reset IFS to its previous value. For Example //a script IFS='\n' unset $IFS -bash: unset: `': not a valid identifier -bash: unset: `': not a valid identifier This code cause an error and does not reset IFS to its original value. unset IFS does. -----Original Message----- From: open-scap-list-boun...@redhat.com [mailto:open-scap-list-boun...@redhat.com] On Behalf Of open-scap-list-requ...@redhat.com Sent: Wednesday, April 12, 2017 4:51 PM To: open-scap-list@redhat.com Subject: Open-scap-list Digest, Vol 97, Issue 14 Send Open-scap-list mailing list submissions to open-scap-list@redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/open-scap-list or, via email, send a message with subject or body 'help' to open-scap-list-requ...@redhat.com You can reach the person managing the list at open-scap-list-ow...@redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Open-scap-list digest..."

IIRC, stigviewer can consume OVAL results.
