Code:
sed 1d file | sort >output

Reattaching the first line back on is left as an exercise, if you even want that.

This assumes that you want to sort on the first field of the file
Code:
awk 'NR==1; NR > 1 {print $0 | "sort -t\| -n -k 1,1"}' file

I want to sort all lines in input - except first [ header ] but i want header on output also.
Example file:
Time
123
1245
122134
123412
123123
1243123
12334
123123

- Time line is header
- sort by key 1reverse and numeric [ sort -k1rn ]
expected outout:
Time
1243123
123412
123123
123123
122134
12334
1245
123

If the input file has a single column then you do not need the sort by key 1
Code:
awk 'NR == 1; NR > 1 {print $0 | "sort -nr"}'
