How do I get detailed information on a warning?

petulia3478

To get full details of a warning you can use the diagnostics option, with the -M option of perl or enable it in the program.

#!/usr/bin/perl 
use diagnostics;

or

$ perl -Mdiagnostics ./yourprog.pl

You can see the output with the diagnostics if you mistype the print statement e.g:

Put this code in a file called hw.pl and run it.

#!/usr/bin/perl
use diagnostics;
pint "Hello, world!\n"

$ perl hw.pl
