Any suggestions for a work-around would also > be most welcome. Because -print0 generates a NULL separated list - so grep will match .iso\0 in the string generated by find and hence not output any list for cpio to read ... One workaround: find . -depth -print | grep -v .iso$ | cpio -pmd /tmp/test James Pearson
