Windows console applications

Operating systems : Windows

Some time ago text-based applications were the only form of software of average end user computer experience. As well as after the graphical user interface programs started to become widespread, console applications used to retain their strong positions. But gradually GUI software virtually superseded text-based applications in daily use of the average end user. However, even now there are console programs that can more or less compete with software of graphical user interface, be useful for the average user to solve various problems and fulfill numerous tasks on modern computers.

Besides file managers, multimedia programs, text editors, web browsers, there are plenty of other text-based programs and utilities for use under Windows: both standalone and those included in MS Windows distributions. For example, ipconfig and netstat for work with network, Windows built-in FTP client useful for some tasks, CommandBurner for command line burning CD / DVD or cdburn with dvdburn from Windows Server 2003 Support Tools for the same, etc.

Extract tar.gz

 

Extracting tar.gz files in Linux, command line: tar zxvf file.tar.gz - z : filter the archive through gzip [ 1 ] - x : extract files from an archive - v : list the files processed - f : use archive file The command extracts the contents of a compressed archive to the current directory. Tar creates an archive of one or several files. Then gzip 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 compressed after - is reflected in the extension of the file ("tar.gz") and requires two procedures to be performed while extracting: decompressing and unpacking. Hence both z (decompress it) and x (unpack it) in the command. [ 1 ] Sources for the option letters description: tar(1) - Linux man page and LinuxCommand.org
