Scalar Variables and Operators

Chop and Chomp

• The chop function removes the last character from the supplied scalar string variable.
• Example:

  $TheString = "Hello World!";
  chop($TheString); # Now $TheString contains "Hello World" without the "!"
  

• The chomp function removes the last character(s) from the string if they correspond to your systems newline character.
• Example:

  $TheString = "Hello World\n";
  $TheString2 = "Hello World";
  chomp ($TheString);
  chomp ($TheString2);
  # $TheString and $TheString2 equal "Hello World" with no "\n"
  

• Both chop and chomp return the characters they deleted.
• Example:

   
  $Name = "Reepicheep";
  $TheChar = chop $Name; # $TheChar = "p", $Name = "Reepichee"
