Well, there are generic ways to do it within perl too, but the bash solution (which the above makes me think you're looking for) is to redirect stderr first to stdout and then redirect stdout to a file. intuitively this doesn't make a whole lot of sense until you see what...
php://input是PHP执行时的外部输入流,一般数据只能读一次(具体看SAPI的实现)。 同理可得到php://stdout和php://output的区别:php://stdout是PHP进程的标准输出流,php://output是返回的结果数据流。 下面用代码验证结论: // file: test.php file_put_contents("php://output", "message sent by output" ...
print STDOUT "Welcome to our little program\n"; print STDERR "Could not open file\n"; (Please note, there is no comma,after the words STDOUT and STDERR in this expression!) If you run this script (perl program.pl) you will see this on the screen: ...

Output from Java applications running in a JVM is normally written to the z/OS UNIX files that are named by the STDOUT and STDERR options in the JVM profile for the JVM. JAVADUMP files are written to the JVM's working directory on z/OS UNIX, and the more
The DEBUG_OUTPUT_XXX output flags are similar to stdout and stderr used with console output. Each output flag is an individual output channel. It’s up to the receivers (callbacks) to decide which of these channels will be listened to, how they’re to be combined (if it all) and how...
The names,stderr,stdin, andstdout, are meant to make error reporting more meaningful. To preserve error reporting, the system makes it an error to close logical unit 0, although it can be reopened to another file. If you want to open a file with the default file name for any preconnect...
