Standard input : Command Line « Language Basics « Perl






Standard input

    

#The script gets user input from the STDIN (standard input) "file." 
#STDIN normally comes from your keyboard. 
#STDIN, STDOUT and STDERR are the pre-defined file handles. 
#In scalar context, the command reads a single line of text from a file. 
#In array context, the <STDIN> command would read in an entire file.


$lang = <STDIN>;

chomp($lang);

print $lang;
