ls behavior

I put this here because it is a 'behavior' type question.. I seem to remember doing ls .* and getting all the .-files, like .profile .login etc. But ls .* doesn't do that, it lsts the contents of every .*-type subdirectory. Is it supposed to? I should think that a -R should be given to...

Unusual Behavior?

Our comp-operator has come across a peculiar �feature'. We have this directory where we save all the reports that were generated for a particular department for only one calendar year.

With that logic this echoes "echo". Question about echo!

echo `echo ` doesn't echoes anything. And it's logic. But echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo" (too much echoing :P):o

iptables DNAT of outgoing destination port, unexpected behavior

Not sure if this should be here or in the security section. I am developing software that dynamically manipulates netfilter/iptables rules (through system() calls of the command strings, I'm not trying to hack the netfilter code). Basically, UDP messages that are sent by an application on, say,...

I am trying to get my history in sync in multiple bash sections and things aren't working the way I expect. Desired behavior, hitting esc-K in all bash sessions (same userid and machine) will use the same history. Observed behavior: Esc-k shows the history of the current session, rather than...

perl::critic::policyparameter::behavior::stringlist

Perl::Critic::PolicyParameter::Behavior::StringList(3pm)User Contributed Perl DocumentatioPerl::Critic::PolicyParameter::Behavior::StringList(3pm)

NAME

       Perl::Critic::PolicyParameter::Behavior::StringList - Actions appropriate for a parameter that is a list of strings.

DESCRIPTION

       Provides a standard set of functionality for a string list Perl::Critic::PolicyParameter so that the developer of a policy does not have to
       provide it her/himself.

       NOTE: Do not instantiate this class.  Use the singleton instance held onto by Perl::Critic::PolicyParameter.

INTERFACE SUPPORT

       This is considered to be a non-public class.  Its interface is subject to change without notice.

METHODS

       "initialize_parameter( $parameter, $specification )"
	   Plug in the functionality this behavior provides into the parameter, based upon the configuration provided by the specification.

	   This behavior looks for one configuration item:

	   always_present_values
	       Optional.  Values that should always be included, regardless of what the configuration of the parameter specifies, as an array
	       reference.

       "generate_parameter_description( $parameter )"
	   Create a description of the parameter, based upon the description on the parameter itself, but enhancing it with information from this
	   behavior.

	   In this specific case, the always present values are added at the end.
