କିଛି ଉଦାହରଣ
In older versions of Perl, one would write the Hello World program as:

    print "Hello World!\n";

In later versions, which support the say statement, one can also write it as:

    use 5.010;
    say "Hello World!";

Good Perl practices require more complex programs to add the use strict; and use warnings; pragmas, leading into something like:

    use strict;
    use warnings;

    print "Hello World!\n";

Here is a more complex Perl program, that counts down the seconds up to a given threshold:

 #!/usr/bin/perl
 use strict;
 use warnings;
 use IO::Handle;

 my ( $remaining, $total );

 $remaining = $total = shift(@ARGV);

 STDOUT->autoflush(1);

 while ( $remaining ) {
  printf ( "Remaining %s/%s \r", $remaining--, $total );
  sleep 1;
 }

 print "\n";

The perl interpreter can also be used for one-off scripts on the command line. The following example as invoked from an sh-compatible shell such as Bash translates the string "Bob" in all files ending with .txt in the current directory to "Robert":

     $ perl -i.bak -lp -e 's/Bob/Robert/g' *.txt
