Shell Hungman 没有在 ubuntu 上运行

Question

我有 shell 脚本，但是当我在 Ubuntu 上运行它时，出现错误:

arithmetic expression expecting primary.

问题出在主程序中，尤其是 nbLigne 行。 .

这是代码:

#!/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
}

谢谢您的帮助!

未在 Ubuntu atm 上测试，但换行

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

至

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

应该管用。
