Stdin

Short for standard input, stdin is an input stream where data is sent to and read by a program. It is a file descriptor in Unix-like operating systems, and programming languages, such as C, Perl, and Java. Below, is an example of how STDIN could be used in Perl.

print "Type something: ";
my $example = <STDIN>;
print "\nYou typed: $example\n";

In the example above, when ran, the script asks you to type something. Whatever is typed is saved in the $example variable and then printed as "You typed: xxxx," where xxxx is what is saved in the variable.
