如何批量复制多级目录下的speed_vs_time.png并重命名归档？

Hey there! Let's sort out this batch file copying and renaming task for you. Below are a couple of straightforward, cross-platform or OS-specific approaches to get this done quickly:

For Linux/macOS (Bash) #

1. First, navigate to your Main_directory:

   cd /path/to/your/Main_directory
   

2. Create the target images folder (if it doesn't exist already):

   mkdir -p images
   

3. Run this loop to copy and rename the files:

   for dir in */; do
       # Define the source file path
       src_file="${dir}case1/results/speed_vs_time.png"
       # Check if the source file exists before proceeding
       if [ -f "$src_file" ]; then
           # Extract the folder name (remove trailing slash)
           folder_name="${dir%/}"
           # Copy and rename the file to the images folder
           cp "$src_file" "images/${folder_name}.png"
           echo "Copied $src_file to images/${folder_name}.png"
       else
           echo "Warning: $src_file does not exist, skipping folder $dir"
       fi
   done
   

For Windows (PowerShell) #

1. Navigate to your Main_directory:

   Set-Location -Path "C:\path\to\your\Main_directory"
   

2. Create the images folder (with -Force to avoid errors if it exists):

   New-Item -ItemType Directory -Name "images" -Force
   

3. Execute this loop to handle the files:

   Get-ChildItem -Directory | ForEach-Object {
       $srcPath = Join-Path -Path $_.FullName -ChildPath "case1\results\speed_vs_time.png"
       # Verify the source file exists
       if (Test-Path -Path $srcPath -PathType Leaf) {
           $destPath = Join-Path -Path "images" -ChildPath "$($_.Name).png"
           Copy-Item -Path $srcPath -Destination $destPath -Force
           Write-Host "Copied $srcPath to $destPath"
       } else {
           Write-Warning "$srcPath not found, skipping folder $($_.Name)"
       }
   }
   

If you prefer a script that works on any OS (as long as Python is installed), use this:

import os
import shutil

# Replace this path with your actual Main_directory path
main_dir = "/path/to/your/Main_directory"  # For Windows: "C:\\path\\to\\your\\Main_directory"
images_dir = os.path.join(main_dir, "images")

# Create the images folder if it doesn't exist
os.makedirs(images_dir, exist_ok=True)

# Loop through each subfolder in Main_directory
for folder_name in os.listdir(main_dir):
    folder_path = os.path.join(main_dir, folder_name)
    # Only process actual directories
    if os.path.isdir(folder_path):
        src_file = os.path.join(folder_path, "case1", "results", "speed_vs_time.png")
        if os.path.isfile(src_file):
            dest_file = os.path.join(images_dir, f"{folder_name}.png")
            # Use copy2 to preserve file metadata like creation date
            shutil.copy2(src_file, dest_file)
            print(f"Successfully copied: {src_file} -> {dest_file}")
        else:
            print(f"Warning: {src_file} does not exist, skipping {folder_name}")

To use this script:

• Replace the main_dir path with your actual directory path
• Save the file as copy_images.py
• Run it with python copy_images.py
