Top Forums UNIX for Beginners Questions & Answers Shall script use and understanding Post 302986286 by rbatte1 on Wednesday 23rd of November 2016 09:59:05 AM

The author does like ; quite a lot. They are not needed at the end of a line in bash and the lastkey=""; -- what does this mean ..... line would give a syntax error similar to:-
Code:
bash: --: command not found

The comment character is a hash #

The error you are seeing is because one or more of the variables being fed into expr are not numeric. Try running it like this:-
Code:
bash -x Reducer

.... although I don't see where you read an input file. You might also manage it with
Code:
bash -x Reducer < inputfile

Using the -x flag will cause it to show you more about what is happening in your code as it runs.


Does this help enough?

locale::language

Locale::Language(3perl) 				 Perl Programmers Reference Guide				   Locale::Language(3perl)

NAME

       Locale::Language - standard codes for language identification

SYNOPSIS

	  use Locale::Language;

	  $lang = code2language('en');	      # $lang gets 'English'
	  $code = language2code('French');    # $code gets 'fr'

	  @codes   = all_language_codes();
	  @names   = all_language_names();

DESCRIPTION

       The "Locale::Language" module provides access to standard codes used for identifying languages, such as those as defined in ISO 639.

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

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying languages. The ones currently supported are:

       alpha-2
	   This is the set of two-letter (lowercase) codes from ISO 639, such as 'he' for Hebrew.

	   This code set is identified with the symbol "LOCALE_LANG_ALPHA_2".

	   This is the default code set.

       alpha-3
	   This is the set of three-letter (lowercase) bibliographic codes from ISO 639, such as 'heb' for Hebrew.

	   This code set is identified with the symbol "LOCALE_LANG_ALPHA_3".

       term
	   This is the set of three-letter (lowercase) terminologic codes from ISO 639.

	   This code set is identified with the symbol "LOCALE_LANG_TERM".

ROUTINES

       code2language ( CODE [,CODESET] )
       language2code ( NAME [,CODESET] )
       language_code2code ( CODE ,CODESET ,CODESET2 )
       all_language_codes ( [CODESET] )
       all_language_names ( [CODESET] )
       Locale::Language::rename_language  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Language::add_language  ( CODE ,NAME [,CODESET] )
       Locale::Language::delete_language  ( CODE [,CODESET] )
       Locale::Language::add_language_alias  ( NAME ,NEW_NAME )
       Locale::Language::delete_language_alias	( NAME )
       Locale::Language::rename_language_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Language::add_language_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Language::delete_language_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
