If the data in the text file is on line 6 then output the data in line 2 to another text file.
You mean column?

Let me try, although I'm not sure I understood you completely:
Code:
$ cat data
Field 1       Field2  Field3   Field4   Field5     Field6

20009756   1        2         1          1           592560
20007654   2        4         45brt      ewfw        55552
20009756   X        2         1          1           592560
20009756   balh        2         1          1           592560
20007654   8.t        4         45brt      ewfw        55552
$ cat aux
592560
55552
$ awk 'NR==FNR{a[$1]=cnt++; next}{if($6 in a){print $2 > "output."$6;} }' aux data
$ cat output.55552 
2
8.t
$ cat output.592560 
1
X
balh

The above awk command will print the second column of a line whose sixth field matches an entry in aux, and print it into a file.
