Is there a way to ignore header lines in a UNIX sort?

Question

I have a fixed-width-field file which I\'m trying to sort using the UNIX (Cygwin, in my case) sort utility.

The problem is there is a two-line header at the top of t

Answer 1

It only takes 2 lines of code...

head -1 test.txt > a.tmp; 
tail -n+2 test.txt | sort -n >> a.tmp;

For a numeric data, -n is required. For alpha sort, the -n is not required.

Example file:
$ cat test.txt

header
8
5
100
1
-1

Result:
$ cat a.tmp

header
-1
1
5
8
100
