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?
