HP UX에서는 되는데 Linux에서 안되는 Shell Script

안녕하세요?

다음과 같은 Shell Script가 있는데 HP UX에서는 되는데 Linux에서는 안되는군요. 아시는분 부탁 드립니다.

#! /bin/sh
#POSIX shell script
#Script name : phone
typeset -i x=0
typeset -i numlines=0
typeset -L30 name
typeset -L30 surn
typeset -R10 extn
numlines=$(cat phonelist | wc -l)
((numlines=numlines - 1))
exec 3<phonelist
while (( x <= numlines ))
do
  read -u3 name[x] surn[x] extn[x]
  ((x = x+1))
done
tput clear
print $$(name[0]} ${surn[0]} ${extn[0]}\n"
x=1
while (( x<=numlines))
do
  print "${name[x]} ${surn[x]} ${extn[x]}"
  ((x=x+1))
done
