Linux provides print queues so that only one job is printed on a given printer at a time. A queue allows several people or jobs to send output simultaneously to a single printer with the expected results.

On systems that have access to more than one printer, you can use lpstat p to display a list of available printers. Use the P option to instruct lpr to place the file in the queue for a specific printer even one that is connected to another system on the network. The following command prints the file named report:.

$ lpr report Because this command does n ot specify a printer, the output goes to the default printer, which is the printer when you have only one printer. The next command line prints the same file on the printer named mailroom:. $ lpr -P mailroom report You can see which jobs are in the print queue by giving an lpstat o command or by using the lpq utility:. $ lpq lp is ready and print .net vs 2010 ean13+5 ing Rank Owner Job Files active max 86 (standard input).

. Figure 5-4. grep searches for a string grep: Searches for a String The grep1 utility searches VS .NET GS1-13 through one or more files to see whether any contain a specified string of characters. This utility does not change the file it searches but simply displays each line that contains the string.

The grep command in Figure 5-4 searches through the file memo for lines that contain the string credit and displays the single line that meets this criterion. If memo contained such words as discredit, creditor, or accreditation, grep would have displayed those lines as well because they contain the string it was searching for. The w (words) option causes grep to match only whole words.

Although you do not need to enclose the string you are searching for in single quotation marks, doing so allows you to put SPACEs and special characters in the search string. The grep utility can do much more than search for a simple string in a single file. Refer to the grep info page and Appendix A, Regular Expressions, for more information.

This utility can display any number of lines, so you can use it to look at only the first line of a file, at a full screen, or even more. To specify the number of lines.
