Question

我正在使用pexpect远程登录到某些计算机并执行一些命令。我需要从登录到该计算机的bash历史记录文件中删除这些命令。我可以通过在命令前面放置一个空格来删除命令（典型方法：p），但是库中仍然打印了一些剩余的日志行。我也需要删除它。是否有任何库级别配置可删除以静默方式登录的命令？

if not (hostname or username or password or commands):
            logging.debug(
                "Skip running remote commands args are empty")
            return None
        from pexpect import pxssh
        results = []
        server = pxssh.pxssh()
        server.login(hostname, username, password)
        for command in commands:
            server.sendline(command)  # run a command
            server.prompt()  # match the prompt
            output = server.before
            result = output.replace(command, '').strip()
            results.append(result)
        server.logout()
        return results
