在UNIX和Linux的某些版本中，有一个横幅命令（通常是/ usr / bin / banner），可以打印出如下的输出：
##### ####### # ##### # # # # # # # # # # # # # # # # # # ##### # # # # ### # # ####### # # # # # # # # # # # # ##### # # # ##### # #
在其他版本中，横幅命令（频繁/ usr / games / banner）会打印出一个巨大的横幅，就像您在1980年用Printshop制作的那样，适合在生日派对上使用。
我倾向于使用横幅为我的脚本，但它本质上是不可移植的，因为这个问题。 UNIX是“旗帜”的一部分，为什么不是POSIX标准的一部分？ 这是一些BSD与SysV的区别，但为什么没有解决？
我知道那里有再现我喜欢的横幅的figlet。 但是这个命令的问题是可移植性。 横幅应该是UNIX的一部分，恕我直言，即使他们需要包括在不同的名字下的两个版本（尽pipe理想的行为应该被合并成一个命令与一个期望的输出选项）。
如何优化std :: map insert（）函数？
URL中是否允许冒号？
我应该允许strerror_r的大小是多less？
如何成功使用RDAP协议而不是whois
如果我使用横幅，在脚本中的可移植性我只是运气不好？
LSB中是否有RPM文件命名约定？
便携式的方式来实现ls的-v标志（即按版本sorting）？
ifstream创build文件，如果它不存在
Windows标准文件位置
因为在POSIX标准化时出现了两种不同的行为，那就是在80年代后期，标准中没有标题。 这不是必须的，没有一个普遍的标准选择为“标准”。
是的，如果您在脚本中使用banner ，那么您运气不佳; 该行为在各个平台上不可靠。
没有什么比直线C更便携
你可能会发现我的粗略草案在这里比修改和扩展更容易修改和扩展（由于隐含的版权，如果没有别的）。 此代码旨在易于阅读和理解，无需任何意见。

所需的横幅是System V横幅，至少在Ubuntu 11上安装sysvbanner软件包以获取它
总是有figlet 。 为unix，windows，dos，mac等提供源代码，希望这可以指导你正确的方向。
此外，还有TOIlet ，可以被认为是figlet ++。
这对unix系统来说并不是必须的，我不确定它为什么会成为标准的一部分。 还有很多其他的事情可以说是标准制定机构应该关注的重要问题。
如果在系统上不可用，您可以简单地安装它或建立一个等效的。
在debian上有一个横幅文件，它有一个包含155行代码的c文件，其中大部分就是字形。 源代码可以在包页面找到。 http://packages.debian.org/testing/misc/sysvbanner
甚至用您选择的脚本语言构建另一个克隆应该不会太困难。

来自bsdmainutils软件包版本8.0.13的banner命令现在称为printerbanner，位于/ usr / bin / printerbanner。
