Actually I just refactored it for unrelated reasons ("next" is easier to type five times than "print NF" and if you want to print the whole line instead it's only one place to change). The fundamental problem is that !(/^9999/ && 1) is true for files which do not match /^9999/.

NAME
Devel::Trace - Print out each line before it is executed (like "sh -x") SYNOPSIS
perl -d:Trace program DESCRIPTION
If you run your program with "perl -d:Trace program", this module will print a message to standard error just before each line is executed. For example, if your program looks like this: #!/usr/bin/perl print "Statement 1 at line 4 "; print "Statement 2 at line 5 "; print "Call to sub x returns ", &x(), " at line 6. "; exit 0; sub x { print "In sub x at line 12. "; return 13; } Then the "Trace" output will look like this: >> ./test:4: print "Statement 1 at line 4 "; >> ./test:5: print "Statement 2 at line 5 "; >> ./test:6: print "Call to sub x returns ", &x(), " at line 6. "; >> ./test:12: print "In sub x at line 12. "; >> ./test:13: return 13; >> ./test:8: exit 0; This is something like the shell's "-x" option. DETAILS
Inside your program, you can enable and disable tracing by doing $Devel::Trace::TRACE = 1; # Enable $Devel::Trace::TRACE = 0; # Disable or Devel::Trace::trace('on'); # Enable Devel::Trace::trace('off'); # Disable "Devel::Trace" exports the "trace" function if you ask it to: import Devel::Trace 'trace'; Then if you want you just say trace 'on'; # Enable trace 'off'; # Disable TODO
o You should be able to send the trace output to the filehandle of your choice. o You should be able to specify the format of the output. o You should be able to get the output into a string. We'll see. LICENSE
