pty是什么单位？

一、pty是什么单位？

Pty -- proprietary 是私人股份公司。不上市的NL-- No liability 一般都是上市公司。而且这样的公司没有statutory or contractual right to recover unpaid calls on partly paid shares。

也就是说，公司发行股票时，只需投资者出一部分股票的钱，剩下的未支付的钱，当公司要求并通知购买股票的投资者付清余款时，才需要支付。

对于上市公司来说，如果投资者收到通知后，没有偿还余款，那么上市公司是无权强行逼迫投资者偿还的。但他们可以取消投资者的股份，然后并重新发布这些股份。

而重新卖这些股份的花费（包括损失的价值），是由不还钱的投资者支付，而且他们必须支付这笔费用。其实澳洲的上市公司，都是NL。有些公司喜欢把它写在公司名字里来吸引不太明白这个概念的投资者。

二、centos pty

在CentOS中了解PTY

PTY，即伪终端（Pseudo Terminal），是计算机领域中一个常用的概念。在Linux系统中，伪终端是非常重要的一部分，特别是在与终端交互、启动终端会话以及执行shell命令等操作时。本文将深入探讨在CentOS操作系统中关于PTY的相关知识。

PTY的概念

PTY是一个虚拟的设备，它充当着终端设备的角色。它由两部分组成：主设备（Master Device）和从设备（Slave Device）。在Linux系统中，主设备用于向应用程序提供终端接口，而从设备则模拟了真实的终端设备，用户可以通过从设备与应用程序进行交互。

当一个程序打开一个伪终端设备时，系统会为该程序分配一个主设备和一个从设备，它们之间通过一个称为伪终端控制器（Pty Master-Slave pty）的设备连接起来，从而实现了程序与终端设备之间的数据传输和交互。

PTY的应用

在CentOS系统中，PTY被广泛应用于各种场景，例如：使用SSH协议远程登录Linux服务器、在终端中启动多个Shell会话、执行远程命令等。通过伪终端，用户可以方便地在不同的终端会话之间切换，进行并发操作，提高工作效率。

PTY的工作原理

当一个程序打开一个伪终端设备时，系统会为该程序分配一个从设备，并将该从设备和主设备通过管道连接起来。通过这种方式，程序可以向从设备写入数据，伪终端控制器将数据转发给主设备，主设备则将数据传输到终端设备中，实现了程序与终端之间的通信。

当用户在终端中输入命令时，终端设备将数据发送给主设备，主设备再将数据转发给从设备，从设备则将数据传递给应用程序，从而实现了用户与程序之间的交互。这一过程保证了数据在终端和应用程序之间的可靠传输。

使用PTY实现多终端会话

在CentOS系统中，用户可以通过使用PTY来实现多终端会话的功能。通过打开多个伪终端设备，用户可以同时在不同的终端会话中执行命令，查看输出并与程序进行交互。这种方式极大地提高了系统的灵活性和效率。

通过在终端中输入命令：sudo gnome-terminal，用户可以打开一个新的终端会话。用户还可以使用Ctrl + Alt + F1/F2/F3等快捷键在虚拟控制台之间切换，同时在多个终端会话之间自由切换操作，方便快捷。

结语

总的来说，在CentOS系统中，PTY扮演着极为重要的角色，它为用户提供了强大的终端交互功能，使用户能够方便地与系统进行交互操作。通过了解PTY的工作原理和应用方式，用户可以更好地利用Linux系统的功能，提高工作效率，实现更多操作场景下的需求。
