The following are examples of pl_who.d.

This is a simple script to see who is executing Perl subroutines. Here it

traces as a few examples programs are executed (from Code/Perl/*.pl).

# pl_who.d

Tracing... Hit Ctrl-C to end.

^C

PID UID SUBS FILE

30817 100 3 ./func_abc.pl

30818 100 3 ./func_slow.pl

30819 100 3 ./func_slow.pl

While tracing, the user with UID 100 executed three Perl programs;

"func_abc.pl" once getting PID 130817, and "func_slow.pl" twice. All

programs called three subroutines.

The following traces a Perl network interface statistics tool, "nicstat"

version 0.99,

# pl_who.d

Tracing... Hit Ctrl-C to end.

This shows the location of libraries and modules from where subroutines were

called.
