Hey

How do I sort an array numerically after the second column?
My values are integers like 1, 2, 3, 4... and they are not unique, so I can't just reverse my hash and sort by keys.

Hey

I am new to programming in general but am trying to work in Perl.

Thanks a million! Very clear explanation so now I actually learned something new and useful. :)

Oki cool thanx.

Used this command:

gawk -F'\t' '{$8=$4;$4=_ }1' OFS='\t' myfile > Newfile

And got the desired output which my program reads as it should:
A*0201 ...

See here's the problem with being a total newbie - don't know what defines the fieldseperator.
I just now that the ^| indicates tabs and the $ is the end-of-line-indicator or something like that....

This is the input file where the current column 4 needs to become column 8:

cat -vet Nordirland_alleler.tab.txt | head

A*0101^IIreland...

Hi

The idea is that I have to...
