Correct me if am wrong

sort -r will display the result in reverse order... it can be used for sorting numeric values also.. and this cmd seems to be working fine for me...

cat file.txt | sort -r

The -n for numeric sort is important.
If "file" contains:
1
10
100
2
20
200
3
30
300

sort -r file
300
30
3
200
20
2
100
10
1

sort -nr file
300
200
100
30
20
10
3

and if you only want the highest number output...
use tail -n 1 (to get the last one).
Code:
[user@host ~]$ sort -n lines.txt
1
2
3
4
9
12
32
45
50

[user@host ~]$ sort -n lines.txt |tail -n 1
50
