There's also a useless use of cat in there. If you wanted, you could do something like this (for all targets except netgroup, which calls revnetgroup inbetween cat and awk): ypservers: $(YPSERVERS) _at_echo "Updating $_at_..." - $(CAT) $(YPSERVERS) | \ - $(AWK) '{ if ($$1 != "" && $$1 !~ "^#.*") print $$0"\t"$$0 }' $^ \ + $(AWK) '{ if ($$1 != "" && $$1 !~ "^#.*") print $$0"\t"$$0 }' $(YPSERVERS) \ | $(DBLOAD) -i $(YPSERVERS) -o $(YPMAPDIR)/$_at_ - $(TMP); \ $(RMV) $(TMP) $_at_ _at_$(DBLOAD) -c -- Dan Nelson dnelson_at_allantgroup.comReceived on Thu Jun 12 2003 - 17:48:40 UTC
