   1 The following are examples of sh_pidcolors.d.
   2
   3 This is the same script as in sh_syscolors.d, except with additional tracing.
   4 As well as the functions, lines and system calls traced in sh_syscolors.d,
   5 this also adds some "pid" provider tracing as a starting point for deeper
   6 analysis.  In this case it adds the probes:
   7
   8       pid$target:a.out:e*:entry,
   9       pid$target:a.out:e*:return
  10
  11 which means, all functions from the /usr/bin/sh binary that begin with
  12 the letter "e". This adds about 34 probes, but you can customize it to be as
  13 inclusive as you like.  It renders the output in color ("colour") using terminal
  14 escape sequences (which you can tweak by modifying the script).
  15
  16 Here it traces the example program, Code/Shell/func_abc.sh.
  17
  18 WARNING: This output is full of terminal escape sequences, so if you are
  19 trying to view this through an editor or web browser - it may look awful.
  20 Try viewing this using "more" (although, depending on your terminal, it
  21 still may look awful).

 549 Here you can see the output showing the path the script follows as it is
 550 executed.
 551
 552 At the end of the sh_syscolor_example.txt file, you can see the steps that the
 553 script goes through when it runs func_a.  The output contains the two
 554 consecutive lines:
 555
 556 \e[1;35m0  12979         14       func_abc.sh:23   line     -- \e[0m
 557 \e[2;35m0  12979         32       func_abc.sh:23   func     -> func_a\e[0m
 558
 559 Here we trace many more events that happen in between these two lines, as seen
 560 below:
