Comments

• We use the hash # character in the beginning of the code line. Example:

  # Print the following text
  echo 'The variable is xpto'
  

• To comment several code lines we use : <<'COMMENT' in the beginning and only COMMENT or other word/identification type in the end of what we want to comment. Examples:

  : <<'COMMENT'
  All
  these
  lines
  of
  code
  are
  commented
  COMMENT
  

  : <<'/////'
  All
  these
  lines
  of
  code
  are
