殼牌Hungman不是在Ubuntu

Question

運行我的shell腳本，但是當我運行它在Ubuntu上，有一個錯誤：

arithmetic expression expecting primary. 

的問題是在主程序中，特別是與線nbLigne。

下面的代碼：

#!/bin/sh 

MotAuHasard() 
{ 
    nbr=$(($RANDOM*$RANDOM%$nbLigne))    #définit la position du mot dans listemot.txt 
    Mot=$(head -$nbr $FichierMot | tail -n 1)  #mot trouvé dans monFichier 

    #la fonction suivante vérifie si le mot est supérieur à 6 caractères, 
    #dans le cas contraire, on ré-initialise la fonction 

    nbcarac1=${#Mot} 
    if [ $nbcarac1 -lt 6 ] 
     then 
     MotAuHasard 
    fi 
} 

Affiche() 
{ 
    MotJeu=$Mot 
    nbcarac2=${#cache} 
    for i in `seq 0 $nbcarac2`; 
    do MotJeu=${MotJeu//${cache:i:1}/-} 
    done 
} 

Decouvre() 
{ 
    cache=${cache//$caractere/"_"} 
} 

testPresence() 
{ 
    testPresence=1 
    for i in `seq 0 $nbcarac1`; 
    do 
    if [ "${Mot:i:1}" = "$caractere" ] 
     then 
     testPresence=0 
    fi 
    done 
} 

testGagne() 
{ 
    testGagne=0 
    for i in `seq 0 $nbcarac1`; 
    do 
     if [ "${MotJeu:i:1}" = "-" ] 
      then 
      testGagne=1 
     fi 
    done 
}

謝謝您的幫助！

在Ubuntu ATM未經檢驗的，但改變線

nbr=$(($RANDOM*$RANDOM%$nbLigne)) 

到

nbr=$(echo "$RANDOM*$RANDOM%$nbLigne" | bc) 

應該工作。
