使用python子进程执行awk命令

import subprocess

def execute_awk_command(awk_command, input_text):
    awk_process = subprocess.Popen(['awk', awk_command], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True)
    output, error = awk_process.communicate(input_text)
    return output, error

awk_command = '{print $1}'  # 示例awk命令，打印第一列
input_text = '1 2 3\n4 5 6\n7 8 9\n'  # 示例输入文本

output, error = execute_awk_command(awk_command, input_text)
if error:
    print('执行awk命令时出错:', error)
else:
    print('awk命令执行结果:', output)
