A Dream Land of Peace!


There are some minute details about perl that we need to take care. So here I take a note for later reminder.

  1. STDERR will print out the error messages to the screen or to a file if you want.

  2. If we have a line of code like:

perl $GetALine = <STDIN>;

It will wait for the user to enter something and then append a line ending character to the string that the user enters.
