3.2: How can I use Perl interactively?

The typical approach uses the Perl debugger, described in the
perldebug(1) manpage, on an "empty" program, like this:

perl -de 42

Now just type in any legal Perl code, and it will be immediately
evaluated. You can also examine the symbol table, get stack backtraces,
check variable values, set breakpoints, and other operations typically
found in symbolic debuggers.


The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
