如何将linux命令的输出保存到字典中？

import subprocess

# 执行Linux命令，并将输出保存到字典中
def save_command_output_to_dict(command):
    output = subprocess.check_output(command, shell=True).decode('utf-8')
    lines = output.strip().split('\n')
    result = {}
    for line in lines:
        key, value = line.split(':')
        result[key.strip()] = value.strip()
    return result

# 示例：将"ls"命令的输出保存到字典中
output_dict = save_command_output_to_dict('ls')
print(output_dict)
