In the next example, the commands to print out a file with line numbers have been placed in an executable file called lpnum, which takes a filename as its argument. The cat command with the -n option first outputs the contents of the file with line numbers. Then this output is piped into the lp command, which prints it. The command to print out the line numbers is executed in the background. lpnum

You may need to reference more than one argument at a time. The number of arguments used may vary. In lpnum, you may want to print out three files at one time and five files at some other time. The $ operator with the asterisk, $*, references all the arguments on the command line. Using $* enables you to create scripts that take a varying number of arguments. In the next example, lpnum is rewritten using $* so it can take a different number of arguments each time you use it: lpnum

also cancel commands before they have finished executing. You can even interrupt a command, starting it again later from where you left off. Background operations are particularly useful for long jobs. Instead of waiting at the terminal until a command has finished execution, you can place it in the background. You can then continue executing other Linux commands. You can, for example, edit a file while other files are printing. Canceling a background command can often save you a lot of unnecessary expense. If, say, you execute a command to print all your files and then realize you have some large files you do not want to print, you can reference that execution of the print command and cancel it. Interrupting commands is rarely used, and sometimes it is unintentionally executed. You can, if you want, interrupt an editing session to send mail and then return to your editing session, continuing from where you left off. The background commands, as well as commands to cancel and interrupt jobs, are listed in Table 11-2. In Linux, a command is considered a process-a task to be performed. A Linux system can execute several processes at the same time, just as Linux can handle several users at the same time. Commands to examine and control processes exist, though they are often reserved for system administration operations. Processes actually include not only the commands a user executes, but also all the tasks the system must perform to keep Linux running. The commands that users execute are often called jobs to distinguish them from system processes. When the user executes a command, it becomes a job to be performed by the system. The shell provides a set of job control operations that enable the user to control the execution of these jobs. You can place a job in the background, cancel a job, or interrupt one. You execute a command in the background by placing an ampersand on the command line at the end of the command. When you do so, a user job number and a system process number are displayed. The user job number, placed in brackets, is the number by which the user references the job. The system process number is the number by which the system identifies the job. In the next example, the command to print the file mydata is placed in the background:
