Works fine on my AIX box :
Code:
$ cat muay.sh
sort -k3nr muay.txt| awk '
NR==1 { max = $3 }
$3<max { exit }
1
'
$ cat muay.txt
1 bob 45
2 joe 89
3 sue 11
4 steve 33
5 averell 89
6 willian 89
7 lucky 9
8 jack 89
$ ./muay.sh
2 joe 89
5 averell 89
6 willian 89
8 jack 89
$

If the delimiter is comma :
Code:
sort -t, -k3nr muay.txt| awk -F, '
NR==1 { max = $3 }
$3<max { exit }
1
'
