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..

split

SPLIT(1)						    BSD General Commands Manual 						  SPLIT(1)

NAME

     split -- split a file into pieces

SYNOPSIS

     split [-a suffix_length] [-b byte_count[k|m] | -l line_count -n chunk_count] [file [name]]

DESCRIPTION

     The split utility reads the given file and breaks it up into files of 1000 lines each.  If file is a single dash or absent, split reads from
     the standard input.  file itself is not altered.

     The options are as follows:

     -a      Use suffix_length letters to form the suffix of the file name.

     -b      Create smaller files byte_count bytes in length.  If 'k' is appended to the number, the file is split into byte_count kilobyte
	     pieces.  If 'm' is appended to the number, the file is split into byte_count megabyte pieces.

     -l      Create smaller files line_count lines in length.

     -n      Split file into chunk_count smaller files.

     If additional arguments are specified, the first is used as the name of the input file which is to be split.  If a second additional argument
     is specified, it is used as a prefix for the names of the files into which the file is split.  In this case, each file into which the file is
     split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''.  If -a is not speci-
     fied, two letters are used as the suffix.

     If the name argument is not specified, 'x' is used.

STANDARDS

     The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A split command appeared in Version 6 AT&T UNIX.

     The -a option was introduced in NetBSD 2.0.  Before that, if name was not specified, split would vary the first letter of the filename to
     increase the number of possible output files.  The -a option makes this unnecessary.
