问是否有任何命令行工具来合并两个srt文件？

EN

pip install pysrt
srt -i shift 1h2m58s cd2.srt

# Open the input file for reading
with open('cd2.srt', 'r') as input_file:
  # Open the output file for writing
  with open('cd2.output.srt', 'w') as output_file:
    # Iterate over each line in the input file
    for line in input_file:
      # Check if the line contains a single integer
      if line.strip().isdigit():
        # Convert the line to an integer
        number = int(line)
        # Add $numX to the number
        number += $numX
        # Write the resulting number to the output file
        output_file.write(str(number) + '\n')
      else:
        # Write the original line to the output file
        output_file.write(line)
