{{task|Basic language learning}}{{selection|Short Circuit|Console Program Basics}}A common practice in computing is to send error messages to a different output stream than [[User Output - text|normal text console messages]]. The normal messages print to what is called "standard output" or "standard out". The error messages print to "standard error". This separation can be used to redirect error messages to a different place than normal messages.

To print a message to standard error,
<lang awk>BEGIN {
pipe it through a shell command:
 
<syntaxhighlight lang="awk">BEGIN {
print "Goodbye, World!"| "cat 1>&2"
}</langsyntaxhighlight>
 
Or write to /dev/stderr:
=={{header|Batch File}}==
 
<lang dos>1>&2 echo Goodbye, World!</lang>
{{works with|gawk}}
The redirection operator <code>1>&2</code> causes all output on stream 1 (standard out) to be redirected to stream 2 (standard error). The redirection can be moved to the end of the line, too.
{{works with|mawk}}
{{works with|nawk}}
<syntaxhighlight lang="awk">BEGIN {
print "Goodbye, World!" > "/dev/stderr"
}</syntaxhighlight>
 
With ''gawk'', ''mawk'' and ''nawk'': a special feature
associates "/dev/stderr" with standard error.
The manuals of ''gawk'' and ''mawk'' describe this feature;
''nawk'' also has this feature.
 
Other implementations might try to open /dev/stderr as a file.
Some Unix clones, like [[BSD]], have a /dev/stderr device node
that duplicates standard error, so this code would still work.
Some systems have no such device node, so this code would fail.
We recommend "cat 1>&2", which is more portable, and works with any Unix clone.

The details on to which name stderr is bound may vary between Smalltalk dialects. If different, a "Smalltalk at:#Stderr put:<name your stream here>" should provide compatibility.

However, all Smalltalks provide a console named "Transcript", where diagnostics is usually sent to (which is convenient, if there is no stderr to look at, as when started in Windows as an exe, vs. a com).<br>Thus:
<syntaxhighlight lang="smalltalk">Transcript show: 'Goodbye, World!'</syntaxhighlight>
 
will work on all, and is the preferred way to do this.
<br>(and yes, when running UI-less as a console program, the global "Transcript" is usually bound to the stderr stream).
 
The above tells the stream to write a string;
you can also tell the string to print itself onto some stream:
<syntaxhighlight lang="smalltalk">'Goodbye, World!' printOn: Stderr</syntaxhighlight>
Both have the same effect.
