面临错误，因为语法错误接近意外标记 fi' 
#/bin/sh
file="C:/khushal/prop.txt"
if [ -f "$file" ]
then
    echo "$file found."
 while IFS= read -r key value
  do
    key=$(echo $key | tr '.' '_')
    eval ${key}=\${value}
     echo "User Id       = " ${db_uat_user}
      echo "user password = " ${db_uat_passwd}
 else
     echo "$file not found."
fi

您没有done与该语句匹配的令牌while ... do。

通常最好通过反转文件测试来短路脚本，这会导致 if .. then .. else 不跨越这么多行。 IE：

#/bin/sh
file="C:/khushal/prop.txt"
if ! [ -f "$file" ]
then
    echo "$file not found."
    exit 1
fi
echo "$file found."
while IFS= read -r key value
do
   key=$(echo $key | tr '.' '_')
   eval ${key}=\${value}
   echo "User Id       = " ${db_uat_user}
   echo "user password = " ${db_uat_passwd}
done
