如何唯一识别文件名？地址流文件分类存储的技术问询

Hey there! Let's work through this filename sorting challenge you're facing. Since you can't rename files within the job and need to split filenames into two groups—those without _1 and those that include it—here are a couple of practical, platform-friendly solutions:

Shell Script (Bash) #

If you're working in a Unix-like environment (Linux, macOS, WSL on Windows), a bash script is quick and straightforward:

• First, set up your output files and clear any old content:

  > no_1_files.txt
  > with_1_files.txt
  

• Then loop through all files, filter out directories, and sort filenames into the right lists:

  for file in *; do
      if [[ -f "$file" ]]; then
          # Check if the filename contains "_1"
          if [[ "$file" == *"_1"* ]]; then
              echo "$file" >> with_1_files.txt
          else
              echo "$file" >> no_1_files.txt
          fi
      fi
  done
  

  • Need to match filenames that end with _1 (e.g., invoice_1 instead of invoice_1_draft)? Adjust the condition to [[ "$file" == *_1 ]].
  • Want to target specific file types? Swap * for something like *.pdf or *.docx.

Python Script (Cross-Platform) #

For a solution that works across Windows, macOS, and Linux, Python is a solid choice—especially if you need more flexibility later:

import os

# Set your target directory (use '.' for current folder)
target_directory = "."
# Define output file names
no_suffix_file = "no_1_files.txt"
with_suffix_file = "with_1_files.txt"

# Write filenames to the correct files
with open(no_suffix_file, "w") as no_1, open(with_suffix_file, "w") as with_1:
    for filename in os.listdir(target_directory):
        full_path = os.path.join(target_directory, filename)
        # Only process actual files, skip directories
        if os.path.isfile(full_path):
            if "_1" in filename:
                with_1.write(f"{filename}\n")
            else:
                no_1.write(f"{filename}\n")

Run this script, and you’ll get two clean text files with your sorted filenames.

Quick Tips #

• Both methods handle filenames with spaces, special characters, and weird symbols—no need to worry about breaking things.
• Since we’re only reading and recording filenames (not modifying the actual files), this won’t interfere with your existing mailing/physical file error issues.
• If you need to scan subdirectories too, let me know—I can tweak the scripts to add recursive support!
