Hello Don,

I'm using Cygwin.

Code:

$ uname -a
CYGWIN_NT-6.1 1.7.28(0.271/5/3) 2014-02-09 21:06 i686 Cygwin

I know the basics of get basename of a file and I could get the name of all files in directory with a for like this:

Code:
for file in *; do; echo $(basename $file); done

but after this, I don't know how to get the date of each file and store all files of one date to a folder of the corresponding date.

After that, I don't have idea how to apply the awk command to the files inside each created directory and create an output file with the name of the respective date in dynamically way.

The target directories could go to /Processed folder that exists already and the output files generated by AWK command could go in /Processed too.

The directories to which the files are to be moved don't exist, since the name of each directory will be taken dynamically from the date of the files. For example, all files that are of date 2014-10-31, should go to folder "Codes-2014-10-31".

For each day the average of files to be moved is around 250 and in total the number of files is around 20,000.

And the number of days to be processed are 60 (2 months).

The output of these two commands, it seems to be exactly the same after trying with a file.

Code:
 
cat FILE-2014-10-30-*| awk 'your awk script' > Codes-2014-10-30.txt
and 
awk 'your awk script' FILE-2014-10-30-* > Codes-2014-10-30.txt

Thanks again for any help.

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.
