Possible bug in sorting a tab-delimited file?

[Sean Li]

Hi, there, 

 

I have a tab-delimited file called "f1.txt".

> cat f1.txt

-573       -6.06

-832       -11.95

 

I want to sort it numerically based on the second column, and expect to
see the result as  following:

-832       -11.95

-573       -6.06

 

However, I use -t \t,  the result turns out to be:

 

> sort -t \t -k 2 -n f1.txt

-573       -6.06

-832       -11.95

 

Is it a bug or just my oversight?  The version of sort I'm using is
"sort 6.4  November 2006".

 

Best

 

Sean
