Awk is much more powerful than that! $ dtrace -l | awk '' $2 !~ /PROVIDER/ { n[$2]++; } END { for (p in n) printf("%d:%s\n",n[p],p)}'' 13:profile 1:fasttrap 15:proc 451:mib 46:fpuinfo 49:sched 462:syscall 12:io 66:sysinfo 49784:fbt 332:sdt 41:vminfo 3:dtrace 22:lockstat And I even skipped the titles ;) alan. -- Alan Hargreaves - http://blogs.sun.com/tpenta Staff Engineer (Kernel/VOSJEC/Performance) Product Technical Support (APAC) Sun Microsystems I''m going in the World''s Greatest shave for Leukaemia.
