I would argue that scraping the ls output in this way is broken and that openembedded is what should be fixed (using stat as Sanya suggests is one good alternative). -- ToddOpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~ Honesty may be the best policy, but it's important to remember that apparently, by elimination, dishonesty is the second-best policy. -- George Carlin pgp9Lq34YAKbs.pgp Description: PGP signature -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

Not that I know of. The "What information is listed" node of the ls info pages describes the characters used to indicate alternate access methods when listing files with '-l' but does not mention a way to suppress this.

RE: what's with that trailing "." for the mode from "ls -l"
Hi, Instead of parsing the output of ls you could use the stat command: stat -c %a Otherwise, you could try removing the ACL from the files (if you can): find . -print0 |xargs -0 -n 1 sudo setfattr -h -x security.selinux Remember that the last character can be: ' ' (blank) no SELinux coverage '.' (dot) ordinary SELinux context only '+' (plus) SELinux ACLs or other things beyond ordinary context Sanya Rajan -Original Message- From: fedora-list-boun...@redhat.com [mailto:fedora-list-boun...@redhat.com] On Behalf Of Robert P.
