Well, I've decided to try to learn dtrace to do some benchmarking, and so I tried to use -c to measure what the command does... except it seems to fail... even the simple: dtrace -n 'syscall:::entry { @num[execname] = count(); }' -c 'echo foo' doesn't work... it gives me: # dtrace -n 'syscall:::entry { @num[execname] = count(); }' -c 'echo foo' foo dtrace: failed to control pid 3766: process exited with status 0 ktrace shows it execing /bin/echo and it running fine, but for some reason dtrace can't handle it... P.S. Why are dtrace and dtraceall seperate? -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
