Commonly Used Debugging Commands

This section describes how to run the Perl built-in debugger with the 'perl -d' option. Commonly used debugging commands are also provided.

The default Perl engine on Linux systems offers a built-in debugging tool. It is an interact command line driven and source line level debugger. To invoke the debugger, you need to run Perl with the debug option: -d. For example, "perl -d MyProgram.pl".

The ActivePerl engine for Windows systems also offers the same built-in debugging tool.

When a Perl program is executed with the debug option, execution will be stopped at the first executable statement and a debug command prompt will be displayed ready to take your debug commands.
