基于原始文件创建/重命名新文件的 MAC 脚本：防止将原始文件扩展名添加到文件名 [重复]

问：

这是一个尴尬的情况，但我会尽力而为。我有一个脚本，旨在根据运行该文件的目录中预先存在的文件生成某种类型的文件。每次我这样做时，它都可以工作，但是具有不同扩展名的输出文件仍然在文件名中包含原始扩展名。 例如：

• BGW公司file0001.mpg
• 新增功能：file0001.mpg.nfo

如何防止终端将原始扩展名打印到其预期扩展名后面的新文件名中？

代码如下;

# syntax check (must have only one parameter: input directory)

if [ -z "$1" ];
then echo "Syntax: $0 <input directory>"
    exit 1
fi

# change to the requested directory and inform the user of such

cd "$1"
echo "Preparing to loop through files in the following directory as requested: "
pwd

# create new directory called "metadata" and inform user

echo "Creating new MI-Files folder within the requested directory..."
mkdir "$1"/MI-Files

# begin creating MediaInfo text outputs from all files in directory and
# placing results in the MI-Files directory

echo "Creating MediaInfo text files..."
COUNTER=0
for i in *.*; do

#   NAME=${i%.*}
    COUNTER=$(("$COUNTER"+1));
    mediainfo "$i">./MI-Files/"$i".nfo;
done

# move metadata directory to the user's desktop

V_HOME=$HOME
mv ./metadata "$V_HOME/Desktop/MI-Files"
