The following is an example of the newproc.d script,

   # ./newproc.d
   dtrace: description 'proc:::exec-success ' matched 1 probe
   CPU     ID                    FUNCTION:NAME

     0   3297         exec_common:exec-success   /usr/bin/mv -f /tmp/mpzIaOZF /usr/share/man/cat1/ls.1

     0   3297         exec_common:exec-success   more -s /tmp/mpzIaOZF

The above output was caught when running "man ls". This identifies all the
commands responsible for processing the man page.
