Sorting exponential notation
Hi,
I just want to sort my file with exponential notation. For example:

Code:
1;2;4;s
1;5e-01;4;s
1;1;4;s

I used sort -gk2, but it does not sort in the correct way. What's wrong?

sort -t\; -k2,2g

Thanks ..it works

the numbers stands for the columns right? 2g = second column wtih exp. notation

2,2 means the sort key starts at column 2 and ends at column2, so col 2 only.

ok thanks .. when I want another column, e.g. only 3 the -k,3,3g
# 6  
Old 09-13-2010
that would be -k3,3g without the comma after the k.

Sorry for asking again: But I tried it on my data and it does not function;(.
So my real data looks like:
XX300890;4.27691979504843e-01;4;KL144469220
XY300890;4.27691979504843e-05;4;KL144469220
XY300890;4.27691979504843e-03;4;KL144469220

And I use your code..to sort the second column... but I do not get the expected result???
