True and false (commands) True and false (commands) In Unix-like operating systems, codice_1 and codice_2 are commands whose only function is to always return with a predetermined exit status. Programmers and scripts often use the exit status of a command to assess success (exit status zero) or failure (non-zero) of the command. The codice_1 and codice_2 commands represent the logical values of command success, because "true" returns 0, and "false" returns 1. The commands are usually employed in conditional statements and loops of shell scripts. For example, the following shell script repeats the "echo hello" loop until interrupted: while true do done The commands
Campbell's Soup Cans they were freshly produced cans without flaws. Occasionally, he chose to depict cans with torn labels, peeling labels, crushed bodies, or opened lids (images right). Sometimes he added related items like a bowl of soup or a can opener (in the image on the right below). Sometimes he produced images of related items without any soup cans such as the box sculpture "Campbell's Tomato Juice Box" (above left), which are not strictly a part of the series although a part of the theme. Many of these works were now being produced at the already acclaimed studio, "The Factory." Irving Blum
