Because of the way sed works, the second -e operates on the original line and not the replaced one, you are wrong and I am (still) correct. [...@samlap Desktop]$ cat file1 AA BB CC DD AA BB CC DD [...@samlap Desktop]$ cat file2 BBBB1 BB BBBB3 [...@samlap Desktop]$ sed -e '/BB/R file2' -e '/BB/d' file1 AA BBBB1 CC DD AA BB CC DD If you wanted to be totally correct, you should actually do: $ sed -e '/^BB$/R file2' -e '/^BB$/d' file1 Laterz, Sam -- 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
