[Bioperl-l] how-to-remove-redundant-lines

[vijayaraj nagarajan]

hi
i have a cluster file with contents like this:

1 2 5 7 8 11
2 5 7 8 11 
3 13 17 19
4 21 45 67
5 7 8 11

Now the 1,2 and 5th lines are redundant. i need to
remove the 2nd and 5th line from the file, while
retaining only the first line, since the first line
contains all the members present in 2 and 5th line...

could anyone suggest me how to parse this file, to
remove such redundant lines using perl.
any help and suggestions in this regard would be
greatly appreciated.

thanks
