You find the name of the linked file with find target -printf "%l\n" You find the new destination for target with ls|grep -A1 "$oldtarget"|tail -1 The end-of-list condition can be handled with an additional dummy file and then an explicit if [ "$newtarget" == "ZZZ_after_the_last" ] approach. Or you can use a trick like "(ls;ls)|grep -A1 ...". Is that enough for you to go on? Take care of the strange characters in filenames, as others have rightly pointed out. -- Roberto Ragusa mail at robertoragusa.it -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
