I was also hoping to run this kind of a command in the array:

What this does is it cds to all of the directories and then prints out the files within them.

Is this also possible using the array created that contains all the directories? I have been unable to get the array to perform what the above command does.
First, note that the command substitution marked in red above is incomplete (no closing quote). Second, there is no need for a command substitution there at all. Third, unless you are doing this in a directory where you know beforehand that there is no possibility of whitespace characters or characters that are special in a filename matching pattern in a directory name, you need to quote your uses of the loop variable. And, finally unless you know that there aren't any backslash characters in your directory names and that none of them start with a hyphen, printf is safer than echo. So, I would change the above code to:
Code:
for i in */; do (cd "$i"; printf '%s\n' "$i" && ls);done

And, if you have an array of directories to process, try:
Code:
dirs=( */ )
for i in "${dirs[@]}"; do (cd "$i"; printf '%s\n' "$i" && ls);done

If I was writing this for my personal use, I'd probably change the printf format string to '\n%s\n' to add a little visual separation between directory listings. But, since I don't mind also have a colon added to the ends of the lines denoting directories, I would replace these loops with:
Code:
ls */
 and
dirs=( */ )
ls "${dirs[@]}"

respectively.

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
