Beware of useless use of cat. Try this (untested):

Code:

#!/bin/ksh

# define constant variables.  If a file name ever has to change, you'll have
# to change it here only.
typeset -r INPUTFILE=BASE.txt
typeset -r OUTPUTFILE=output.txt
typeset -r MATCH_TEXT=BASE

# Create or zero out the OUTPUTFILE if it already exists.
> $OUTPUTFILE

# Read INPUTFILE a line at a time.  The line read goes into the variable "line".
while read line
do
  # Call XK passing the line read in and save the output in xk_out.
  xk_out=$(XK $line)

  # If the first 4 characters of the output = $MATCH_TEXT, append the entire line read to
  # OUTPUTFILE.
  if [[ ${xk_out:0:4} == $MATCH_TEXT ]]; then
    print $line >> $OUTPUTFILE
  fi
done < $INPUTFILE

exit 0

mp3wrap

MP3WRAP(1)						      General Commands Manual							MP3WRAP(1)

NAME

       mp3wrap -- Utility for mp3 wrapping

SYNOPSIS

       mp3wrap [options]  OUTPUTFILE  f1.mp3  f2.mp3  [f3.mp3]...

DESCRIPTION

       Mp3Wrap	is  a  free  command-line  utility,  which wraps two or more mp3 files in one large playable file, without losing filename and ID3
       informations. It's useful to make large files easy to download on internet and then easy to split again in few seconds. You can split orig-
       inal files using mp3splt: http://mp3splt.sourceforge.net

       Mp3Wrap	will  create a file named: OUTPUTFILE_MP3WRAP.mp3.  It's important you don't remove the MP3WRAP string, because this will tell the
       split program Mp3Splt that the file is wrapped and can be splitted just with -w option.	There is also the possibility to specify a  custom
       extension to created file (such as "OUTPUTFILE - MP3WRAP - wrapped by me.mp3"). This can be done using config file (see below), just adding
       the line "EXT=my ext.mp3" into it.  Note that your custom extension must contain MP3WRAP string anywhere, otherwise program will add it	by
       itself.

       Mp3Wrap	will also add to the file a ID3v2 containing informations on how to split the file; you can change Title and Album tags but PLEASE
       DO NOT REMOVE THE COMMENT.

OPTIONS

       -a	 Add specified files to an existing Mp3Wrap file. Files are appended and the index is updated.

       -l	 List all files wrapped into a Mp3Wrap file. Doesn't extract anything

       -v	 Verbose mode. Mp3Wrap will display additional informations on process and, when using list option (-l) it will  show  many  extra
		 infos on wrapped files.

CONFIGURATION FILE

       For Linux version valid configuration files are:

	      ~/.mp3wrap (in home directory)

	      .mp3wrap (in the dir you are in that moment).

       For WIN32 version:

	      PROG_DIR/mp3wrap.ini (dir where mp3wrap.exe is)

	      mp3wrap.ini (in the dir you are in that moment).

       FILE FORMAT

       The file consists of key-value pairs in the form
	       KEY=value
       where key contains no whitespace and no equal signs.  value will be all of the text after the equal sign until (but not including) the end-
       ing newline.  Beware of extra spaces at the end of the line!  They will probably be interpreted as part of the option value.

       Valid option keys are:

	      EXT    The extension mp3wrap will append to created files.

       Here is an example:
	      EXT=_MP3WRAP_wrapped by me.mp3

EXAMPLES

       mp3wrap album.mp3 file1.mp3 file2.mp3 file3.mp3 file4.mp3

       mp3wrap -v album.mp3 file*.mp3

       mp3wrap -a album.mp3 file5.mp3 file6.mp3

       mp3wrap -l album.mp3

       mp3wrap -lv album.mp3
