I don't think above code is working fine. Having corrected several logical and syntactical errors, I'm still not sure I understand what you are doing - you have a list of six name constants, and six variables named identically. The latter are used to hold either a character string alternative name to be read from stdin (user terminal) or, if that is missing, an integer word count for, again, text constants. In the end, if an alternate name is entered, you output that, otherwise the word count for the respective text constant in a /tmp file. On top, your recursive use of functions is somewhat unorthodox.

Assuming you have a recent bash, and names in a file like
Code:
Kim
Lee
Jack
Sam
Nick
Smith

, try this
Code:
mapfile -tO1 ORIG <file
mapfile -tO1 NAMES <file
select NAME in ${NAMES[@]}
        do [ $REPLY -eq 0 ] && break
           read -p "Enter ${NAMES[$REPLY]} " NAMES[$REPLY]
        done
for i in ${!ORIG[@]}
        do printf "%s(" ${ORIG[$i]}
           [ "${ORIG[$i]}" == "${NAMES[$i]}" ] && 
                printf "%s)\n" $(grep -c ${NAMES[$i]} /tmp/list) ||
                printf "%s)\n" "${NAMES[$i]}"
        done

to reproduce what I think you want to achieve.

locale::codes::langext5.18

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

NAME

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

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. 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 = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
