Erro na função for

Eu estava instalando alguns módulos do webmin e encontrei um que me dá as estatísticas em tempo real do squid.

O problema é que ao tentar acessar esse modulo ele me dá o erro:
/usr/share/webmin/sq-real-mon-1.0/real.cgi: 31: Syntax error: Bad for loop variable

O que pode ser?

Tá aí o script:

#!/bin/sh
