1 Contents - Command Summary 2 3 The following is a list of commands found in the DTraceToolkit, along 4 with their directory location. 5 6 Generally commands that end in a ".d" are DTrace scripts, and commands 7 that don't are DTrace scripts wrapped in another language (eg, shell 8 or Perl). See the Docs/Readme for instructions for finding their docs. 9 10 DTraceToolkit/ 11 dexplorer run a series of scripts and archive output 12 dtruss process syscall info.
