!p tries to sh p

geoffleach has asked for the wisdom of the Perl Monks concerning the following question:

This is a new installation, so presumably I've failed to install a module. Term::ReadLine is installed, if that matters.

 DB<2>!p
/bin/bash: p: command not found
Undefined subroutine &DB::db_warn called at /usr/share/perl/perl5db.pl
+ line 6738.

That's documented try `h` to read the help text. update If you want debugger commands disabled start with whitespace or semicolon. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :)}	[reply] [d/l]

Let me restate the problem. Suppose I say '>p $foo'. Then later on I wish to repeat the action, so instead of saying '>p $foo', I say '>!p'. As I understand the doc, that is supposed to repeat the last instance of the p command, in this case '>p $foo'. In the doc, its pointed out that recallCommand and ShellBang are both set to '!'. On the last version of perldb, the ! worked as I expected; in this version it appears to be running it as ShellBang. I'm assuming that this was not intenced.	[reply]

Without version info I can only guess. But I only use Ctrl-r to recall commands, though YMMV! Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :)}	[reply]
