无法从bash中的用户输入读取变量

我尝试运行朋友的脚本，尝试输入一些变量时出现此错误：

: bad variable nameead: reload
: not foundsh: 10: bin/reload.sh: 
bin/reload.sh: 11: bin/reload.sh: Syntax error: word unexpected (expecting "in")

问题出在哪儿？这是sh脚本的代码：

#!/bin/bash

echo ""
echo "Выберите необходимое действие:"
echo "    1 - reload."
echo "    2 - db."
echo "    3 - tests."
echo "    0 - exit."
read reload

case $reload in
1)
echo "reload."
