bash 脚本可以从文件名列表中提取名称、版本号和扩展名吗

问：

我在创建 Bash 脚本时遇到问题，该脚本将从文件名列表中提取应用程序名称、版本号和可能的扩展名，例如：

1. 应用程序名称-1-v1.2.3.AppImage
2. 应用名称2-V999.2.31.AppImage
3. 另一个应用程序-v123.456.789
4. 然而-另一个-例子-4-V0.0.1.extA

对于上述示例，应用程序名称为：

1. 应用程序名称-1
2. 应用名称2
3. 另一个应用程序
4. 然而-另一个例子-4

版本号为：

1. 1.2.3
2. 999.2.31
3. 123.456.789
4. 0.0.1

扩展将是：

1. “应用图像”
2. “应用图像”
3. ""
4. “extA”

所有文件名的版本号前面都以 v 或 V 开头，但可能有扩展名，也可能没有扩展名。

我尝试了在 Google Bard 的帮助下创建的以下脚本：

#!/bin/bash

# Function to parse a filename and separate out the base name, version number, and extension
function parse_filename() {
    # Get the base name of the file
    basename=${1##*/}

    # Get the extension of the file
    extension=${basename##*.}

  # Remove the extension from the base name
  basename=${basename%.*}

  # Get the version number of the file
  version=${basename##*-}

  # Strip any leading or trailing spaces from the base name and version number
  basename=${basename## }
  basename=${basename%% }
  version=${version## }
  version=${version%% }

  # If the version number is not in the form digits.digits.digits, then set the version number to an empty string
  if ! [[ "$version" =~ ^[0-9]+\.[0-9]+\.[0-9]+$ ]]; then
      version=""
  fi

  # If the version number is empty, then the version number is the extension
  if [[ -z "$version" ]]; then
      version="$extension"
  fi

  # If the base name is empty, then the base name is the filename without the extension
  if [[ -z "$basename" ]]; then
      basename=${1%.*}
  fi
}

echo "Running script: $0"

# Get the list of filenames from the user
filenames=("$@")

# Iterate over the list of filenames and parse each one
for filename in "${filenames[@]}"; do
    echo "Processing filename: $filename"
    # Parse the filename and get the base name, version number, and extension
    parse_filename "$filename"

  # Print the results to the: console
  echo "Base name: $basename"
  echo "Version number: $version"
  echo "Extension: $extension"
  echo
done

但是，这不会产生正确的输出：

Running script: ./filename-parser.sh
Processing filename: name-of-application-1-v1.2.3.AppImage
Base name: name-of-application-1-v1.2.3
Version number: 
Extension: 

Processing filename: app-name2-V999.2.31.AppImage
Base name: app-name2-V999.2.31
Version number: 
Extension: 

Processing filename: another-application-v123.456.789
Base name: another-application-v123.456
Version number: 
Extension: 

Processing filename: yet-another-example-4-V0.0.1.extA
Base name: yet-another-example-4-V0.0.1
Version number: 
Extension: 

这在 bash 脚本中是否可能，或者我是否需要求助于 Python 或其他东西。
