lpr
The lpr command in Linux is used to print a file to a printer. It sends the file to the printer spooler, which is a program that queues up print jobs and sends them to the printer when it is ready.
The syntax for the lpr command is as follows:
The file argument specifies the file to print.
The options argument specifies additional options for the lpr command. The most common options are as follows:
-P: Specifies the printer to use.-n: Specifies the number of copies to print.-o: Specifies additional options to the printer.
For example, the following command prints the file file.txt to the printer printer1:
The lpr command is a basic but essential command for printing files in Linux. It is important to note that the lpr command does not actually print the file immediately. Instead, it sends the file to the printer spooler, which will print the file when it is ready.
Here are some additional things to keep in mind about the lpr command:
The lpr command must be run as root or by a user who has permission to print to the specified printer.
The lpr command can only be used to print files to printers that are configured on the system.
The lpr command can be used to print files to printers that are located on different machines on the network.
It is important to be aware of these limitations when using the lpr command, so that you do not accidentally print a file to a printer that you do not have permission to use, or so that you do not print a file to a printer that is not available.
