Hi,

I am new to Perl, I was wondering if anyone have sample code to sort multiple columns based on positional data file(the data is not delimited by any characters). I need to sort based on Col1, Col2 and Col5 and create the output file. I would appreciate if someone can help me out with this.

TIA, Prabal

===============

This is the input file:

Col1      Col2         Col3  Col4     Col5         Col6

D1001     SNAM1        1     102      XYZ2234      22.12
D1002     SNAM2        1     201      PQR2234      12.12
D1002     SNAM2        2     202      PQR2234      32.12
D1002     SNAM2        3     203      PQR2234      52.12
D1002     SNAM2        4     204      PQR2234      37.12
D1001     SNAM1        2     103      XYZ1234      22.12

This is the output file I am expecting:

D1001      SNAM1           1     101      XYZ1234       21.11
D1001      SNAM1           2     103      XYZ1234       22.12
D1001      SNAM1           4     104      XYZ1234       22.12
D1001      SNAM1           1     102      XYZ2234       22.12
D1002      SNAM2           1     201      PQR2234       12.12
D1002      SNAM2           2     202      PQR2234       32.12
