The dvips command does not accept input from stdin, so the script may need to create a temporary file and copy stdin to that file before calling dvips.
dvips命令不接受来自stdin 的输入，所以这个脚本可能需要创建临时文件，在调用 dvips之前把 stdin拷贝到临时文件。

Specifying stdout or stdin allows ontape to use pipes (an OS provided buffer mechanism to connect separate programs to a data stream) for archives and restores.
可以指定stdout或stdin，允许ontape在存档和恢复的过程中使用管道（OS提供的一种缓冲机制，将不同的程序连接起来传递数据）。
When activity occurs, inetd maps the incoming request to standard input (stdin), standout output (stdout), and standard error (stderr) and launches the proper daemon.
当发生活动时，inetd 把入站请求映射到标准输入 (stdin)、标准输出 (stdout)和标准错误 (stderr)，并启动适当的守护进程。
Another alternative is to reference the script when you first start up the ij application, essentially replacing stdin with the contents of the file (see Listing 12).
另一个备选方案是在第一次启动ij应用程序时引用脚本，实际上就是使用该文件的内容替换stdin(参见清单12)。
When the user is typing a command on the command line-that is, the shell he or she is using-the user only sees stdin, or standard in-that is, input that the user or a program provides.

This does the same as example 1, but in this case, selpg is reading its stdin, which has been redirected by the shell/kernel to come from "input_file" instead of an explicitly named filename argument.
该命令与示例1 所做的工作相同，但在本例中，selpg读取标准输入，而标准输入已被shell／内核重定向为来自“input_file”而不是显式命名的文件名参数。
