The following shell script works with any amount of whitespace-delimited columns
Code:
#!/bin/sh
awk '
NR==1 {x=NF/2}
{
  line=$0
  if (NR==FNR) {
    sub("[[:space:]]+$","",line)
    for (i=NF; i>x; i--) sub("[[:space:]]+[^[:space:]]+$", "", line)
  } else {
    for (i=1; i<=x; i++) sub("[^[:space:]]+[[:space:]]+", "", line)
  }
  print line
}
' "$1" "$1"

The shell script takes the file name as parameter.

output should be display col1 and col2 below col1 and col2
col3 col4 col5 col6 should be display.

Every post you have submitted has different requirements for which fields are to be printed on which lines.

There is no pattern I can see that tells us which input fields should be printed on which output lines for an input file that contains N fields. When there were 20 input fields, it appeared that you wanted fields 1-10 printed followed by field 11-20. When there were 6 input fields, first you said you wanted fields 1-3 printed followed by fields 4-6; but now when there are 6 input fields you want fields 1-2 printed followed by fields 3-6.

Please go back to the beginning and explain clearly in English how your script is supposed to determine how many sets of output lines are to be created for the input lines and which input fields are supposed to appear in each set of output lines. Without a clear specification of what you want (other than saying that every suggestion provided is not producing the right output, even though it exactly matches the sample output you said you wanted), we are all wasting our time.

AND, PLEASE use CODE tags when displaying sample input, sample output, and sample code segments.

a little bit verbose, but should be a good starting point - hopefully I understood the reqs.
To get fields 1 and 2: awk -f priti.awk myFile
To get fields 3 and 5: awk -v fld='3 5' -f priti.awk myFile
where priti.awk is:
Code:
{
  if (!fld) fld="1 2"
  split(fld, t, FS)
  for(i=1;i in t;i++)
    fldA[t[i]]
}
{
  for(i=1; i<=NF;i++)
   if (i in fldA) printf("%s%s", $i, OFS)
   else
     recA[FNR]=(FNR in recA)?recA[FNR] OFS $i:$i
  printf ORS
  fnr=FNR
}
END {
  for(i=1;i<=fnr; i++)
    if (i in recA)
     print recA[i]
}
