Line 254:
There is no explicit way (ie <tt>isatty()</tt>)to do this; however, if we ''assume'' that standard input ''is'' a terminal, we can check if the input stream has been redirected (presumably to something other than a terminal).
<lang Nemerle>def isTerm = System.Console.IsInputRedirected;</lang>
=={{header|Nim}}==
Using function "isatty" of standard module "terminal" which accepts a File as argument.
<lang Nim>import terminal
echo if stdin.isatty: "stdin is a tty" else: "stdin is not a tty"</lang>
{{out}}
<pre>Command: ./check_input_dev
Result: stdin is a tty</pre>
<pre>Command: ./check_input_dev <somefile
Result: stdin is not a tty</pre>
