Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations.

The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application.

Extract tar.bz2

 

Extracting tar.bz2 files in Linux, command line: tar jxvf file.tar.bz2 - j : filter the archive through bzip2 [ 1 ] - x : extract files from an archive - v : list the files processed - f : use archive file The command extracts the contents of a bzip2 compressed archive to the current directory. Tar creates an archive of one or several files. Then bzip2 is used to compress it. Or both processes are made at once by tar only, with corresponding options employed. The duality of nature - archived and then compressed - is reflected in the extension of the file ("tar.bz2") and requires two procedures to be performed while extracting: decompressing and unpacking. Hence both j (decompress it) and x (unpack it) in the command. [ 1 ] Sources for the option letters description: tar(1) - Linux man page and LinuxCommand.org
