The trick is to use the 's' command in sed and actually add a real newline in the substitution field. But the newline needs to be preceded by a '\'. The script then contains two lines. Here is a sample sed script which will add a line '#Addendum to comment 2' right below '#comment 2': s/#comment 2/#comment 2\ #Addendum to comment 2/ The output of this script executed on the example you gave us is: #comment 1 #comment 2 #Addendum to Comment2 #comment 3 Hope this helps, Michael -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
