This is really good.. And it works as well Smilie

Many thanks!

Could you explain a bit more about the variable?
- What does the a mean in the split ?
- what does the [2] do in the variable ?

edit: Ok, done some google on it and this explains it pretty good:

Code:

split(string, array, fieldsep)
    This divides string into pieces separated by fieldsep, and stores the pieces in array.
    The first piece is stored in array[1], the second piece in array[2], and so forth. 
    The string value of the third argument, fieldsep, is a regexp describing where to split string (much as FS can be a regexp describing where to split input records).
    If the fieldsep is omitted, the value of FS is used. split returns the number of elements created. The split function, then,
    splits strings into pieces in a manner similar to the way input lines are split into fields. For example:

    split("auto-da-fe", a, "-")

    splits the string `auto-da-fe' into three fields using `-' as the separator. It sets the contents of the array a as follows:

    a[1] = "auto"
    a[2] = "da"
    a[3] = "fe"

again many thanks!

Still have to do some tweaking (as you said) because some Dirs have spaces in them..

NAME

       split - split a file into pieces

SYNOPSIS

       line_count] suffix_length] [file [name]]

       nsuffix_length] [file [name]]

   Obsolescent
       n] [file [name]]

DESCRIPTION

       reads  file  and  writes  it  in  pieces  (default  1000 lines) onto a set of output files.  The name of the first output file is name with
       appended, and so on lexicographically, up to (only ASCII letters are used, a maximum of 676 files).  If no output name  is  given,  is  the
       default.

       If no input file is given, or if is given instead, the standard input file is used.

   Options
       recognizes the following command-line options and arguments:

	      The input file is split into pieces
			     line_count lines in size.

	      suffix_length  letters  are  used  to  form the suffix of the output filenames.  This option allows creation of more than 676 output
			     files.  The output file names created cannot exceed the maximum file name length allowed in the directory	containing
			     the files.

	      The input file is split into pieces
			     n bytes in size.

	      The input file is split into pieces
			     n x 1024 bytes in size.  No space separates the n from the

	      The input file is split into pieces
			     n x 1048576 bytes in size.  No space separates the n from the

	      The input file is split into pieces
			     n lines in size.  This option is obsolescent and is equivalent to using the option.

EXTERNAL INFLUENCES

   Environment Variables
       determines the locale for the interpretation of text as single- and/or multi-byte characters.

       determines the language in which messages are displayed.

       If  or  is  not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
       variable.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of

       If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are  set  to	"C".   See
       environ(5).

   International Code Set Support
       Single- and multi-byte character code sets are supported.
