Thank you, I tried your script.
It is working close to what I need.
I tweaked it a bit to meet my exact requirements.

Thanks again

Should be easy to change the script into something more luxerary, it just presents a concept.

Code:
#!/usr/bin/bash
NUMOUT=${1}

NUMFILES=`ls input* | wc -l`

((IN_PER_OUT=${NUMFILES} / ${NUMOUT} + 1))

CURRENT=1
OUT=1
ls input* | while read FILE
do
  if [ ${CURRENT} -eq 1 ]
  then
    cat ${FILE} > output_${OUT}.txt
  else
    cat ${FILE} >> output_${OUT}.txt
  fi

  ((CURRENT=${CURRENT}+1))
  if [ ${CURRENT} -gt ${IN_PER_OUT} ]
  then
    CURRENT=1
    ((OUT=${OUT}+1))
  fi
done
