If you want to have multiple entries for a particular column (for instance, you want a program to run at 4:00 am, 12:00 pm, and 5:00 pm), then you need to have each of these time values in a comma-separated list Be sure not to type any spaces in the list For the program running at 4:00 am, 12:00 pm, and 5:00 pm, the Hour values list would read 4,12,17 Newer versions of cron allow you to use a shorter notation for supplying fields For example, if you want to run a process every two minutes, you just need to put /2 as the first entry Notice that cron uses military time format For the Day_Of_Week entry, 0 represents Sunday, 1 represents Monday, and so on, all the way to 6 representing Saturday Any entry that has a single asterisk (*) wildcard will match any minute, hour, day, month, or day of week when used in the corresponding column When the dates and times in the file match the current date and time, the command is run as the user who set the crontab Any output generated is e-mailed back to the user Obviously, this can result in a mailbox full of messages, so it is important to be thrifty with your reporting A good way to keep a handle on volume is to output only error conditions and have any unavoidable output sent to /dev/null Let s look at some examples The following entry runs the program /bin/ping -c 5 serverB every four hours:

Simple Secure Portable Object-oriented Robust Multithreaded Architecture-neutral Interpreted High performance Distributed Dynamic

Figure 18-14. SPOT will count down from three to one. After the countdown ends, we need to display Pressed or Not Pressed on the LCD screen. To do this, we ll drop in another VARIABLE block. This time I m going to choose my Pressed variable again, but I m changing its Action section option to Read (see Figure 18-15).

or, using the shorthand method:

Two of these buzzwords have already been discussed: secure and portable Let s examine what each of the others implies

Java was designed to be easy for the professional programmer to learn and use effectively Assuming that you have some programming experience, you will not find Java hard to master If you already understand the basic concepts of object-oriented programming, learning Java will be even easier Best of all, if you are an experienced C++ programmer, moving to Java will require very little effort Because Java inherits the C/C++ syntax and many of the object-oriented features of C++, most programmers have little trouble learning Java

Here is an entry that runs the program /usr/local/scripts/backup_level_0 at 10:00 pm every Friday night:

Although influenced by its predecessors, Java was not designed to be source-code compatible with any other language This allowed the Java team the freedom to design with a blank slate One outcome of this was a clean, usable, pragmatic approach to objects Borrowing liberally from many seminal object-software environments of the last few decades, Java manages to strike a balance between the purist s everything is an object paradigm and the pragmatist s stay out of my way model The object model in Java is simple and easy to extend, while primitive types, such as integers, are kept as high-performance nonobjects

The multiplatformed environment of the Web places extraordinary demands on a program, because the program must execute reliably in a variety of systems Thus, the ability to create robust programs was given a high priority in the design of Java To gain reliability, Java restricts you in a few key areas to force you to find your mistakes early in program development At the same time, Java frees you from having to worry about many of the most common causes of programming errors Because Java is a strictly typed language, it checks your code at compile time However, it also checks your code at run time Many hard-to-track-down bugs that often turn up in hard-to-reproduce run-time situations are simply impossible to create in Java Knowing that what you have written will behave in a predictable way under diverse conditions is a key feature of Java
