Debugging perl

Write error-free programs from development to deployment!

Sidestep disaster with the tips, techniques, and expert insights contained in this one-of-a-kind resource. Debugging Perl shows you,
step-by-step, how to fix buggy code and prevent errors from ever slipping into your programs. All the details you need to know are here--from
avoiding syntax, logic, and variable problems as you program to troubleshooting with the Perl debugger, profiler, and compiler. Plus, you'll get
design tips, little-known traps to watch out for, and a cross-referenced appendix of error messages. When your Perl scripts must run cleanly
on every system every time, turn to the real-world solutions offered in this unique handbook.
Learn to:

• Optimize your code using the Perl debugger, profiler, and compiler
  
• Troubleshoot variable expressions, regular expressions, compile-time statements, run-time outputs
  
• Stamp out bugs caused by syntactical and logical mistakes
  
• Implement subroutines, modules, and expressions to automatically detect potential problems
  
• Trap errors using manual techniques, the Perl debuggers, and through the use of Perl's pragma system
  
• Manage Perl memory usage and control system resources
  
• Evaluate your scripts using test harnesses, code breaking, and system stress calculations
