stderr

Meanwhile , the selpg process runs in the background , with stdout and stderr both redirected to files .

同时，selpg进程在后台运行，并且标准输出和标准错误都被重定向至文件。

Stderr the standard error is used only for diagnostic messages .

标准错误只是用来诊断消息的。

Stderr is the standard error stream , which displays error output from commands .

stderr是标准错误流，显示命令中的错误输出。

The outlet is called the standard error device ( usually referred to as stderr ) .

此出口称为标准错误设备（通常简称为stderr）。

Another example is to redirect to standard error ( sys . stderr )

另外一个例子是重定向给标准错误（sys.stderr）

STDERR prints to the screen when a command fails .

STDERR则对应于一个命令失败时的屏幕输出。

Similarly , you 'd use2 | to pipe stderr to another program .

与之类似，您可以使用2将stderr通过管道传递到另一个程序。

Qlog is nice when you don 't want to write printf STDERR every time .

如果不希望每次编写printfSTDERR，那么qlog将非常有用。

There are times when you may need to have both stdout and stderr written to the same file or device .

有时候，可能需要把stdout和stderr写到同一个文件或设备。

The-t option echoes each command to stderr before each command is executed .

t选项可以在执行每个命令之前将命令回显到stderr。

In traditional programming languages such as C , you would use STDIN , STDOUT , and STDERR to accomplish this .

在诸如C之类的传统编程语言中，您将使用STDIN、STDOUT和STDERR完成此操作。

The stderr of the commands wasn 't redirected , so all three utilities print error messages to the terminal .

这些命令的stderr未进行重定向，因此所有三个实用工具都会将错误消息打印到终端上。

Unless redirected elsewhere , the stdout and stderr streams from the background process are directed to the controlling terminal .

除非被重定向到其他地方，否则来自后台进程的stdout和stderr流将被定向控制终端。

These are sometimes called stdin , stdout , and stderr after the global variables that represent them in every C program .

有时将它们称为stdin、stdout和stderr，这是在所有C程序中用来表示它们的全局变量。

You cannot use2 | to pipe stderr alone , at least , not with the tools we have learned so far .

您不能使用2单独导出stderr，至少使用我们目前所了解的工具还不能这样做。

If you want to ignore all output , use the > & operator to send stdout and stderr to the bit bucket .

如果您希望忽略所有的输出，可以使用>&操作符以便将stdout和stderr丢弃。

( The stderr redirect to null is due to a scalar dropping issue in threads . pm ) .

（stderr重定向为null是由于threads.pm中的标量（scalar）释放问题）。

However , you can change the source of stdin and the eventual destinations of both stdout and stderr .

不过，您可更改stdin的源以及stdout和stderr的目标。

Because stderr wasn 't redirected by the > or the pipe , error messages are printed to stdout .

由于stderr没有通过>或管道进行定向，因此错误消息将被打印到stdout。

Log files and task status displays in the graphical user interface let you know if a task failed and provide stderr output to help understand what went wrong .

通过图形用户界面中所显示的日志文件和任务状态，您可以了解一项任务是否失败，并且还提供了stderr输出，以帮助您了解何处出现了问题。

Here , stdout goes to output_file while anything written to stderr goes to error_file .

这里，将标准输出写至outputfile，而将所有写至标准错误的内容都写至errorfile。

So most of the time , you will want to direct stdout to a file for safe keeping , and watch stderr for progress and result summaries .

这样在大部分时间里，为了安全保管，您将会把stdout定向到一个文件，并监视针对进程和结果概要的stderr。

Xtrace : iprint = awt activates method trace and set the output to stderr with indentations .

iprint=mt激活方法跟踪并将输出发送到stderr，进行缩进。

Combining STDOUT and STDERR in this way prevents STDERR output from showing up on the system console and enables the program to parse it .

以这种方法合并STDOUT和STDERR，将阻止STDERR输出在系统控制台上显示并允许程序解析它。

If you 've been paying attention , you 've probably noticed that the standard error ( stderr ) stream isn 't represented in any of those examples .

如果您仔细观察，那么可能会发现，前面的这些示例中并没有出现标准错误（stderr）流。

This accepts a single argument , the filehandle of the file where you want errors ( normally sent to STDERR ) to be written .

该函数只有一个参数，即您用来写入错误信息的文件的文件句柄（通常会将该信息发送到STDERR）。

If there are errors in your script or command , you won 't see a standard error ( stderr ) unless you pipe it to stdout .

如果命令或脚本出现错误，您将看不到标准的错误（stderr），除非您通过竖线将它添加到stdout。

It is worth noting that code_recognizer.py sends its ( large ) test result file to STDOUT , but puts some friendly messages on STDERR .

值得注意的是，coderecognizer.py将它的（大的）测试结果文件发送到STDOUT，而将一些友好的消息放在STDERR里。

It writes your string argument to stderr ( standard error ), followed by a colon and a space , then the system error message followed by a newline .

它先将您的字符串参数写至标准错误（提供它用于定制消息），接下来写入一个冒号和一个空格，然后是系统错误消息，后面是新的一行。

STDIN , STDOUT , STDERR , files , and in-memory data stacks are all handled in a uniform and elegant fashion .

文件和内存内部数据栈都以统一而优雅的方式处理。
