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 But gradually GUI software virtually superseded text-based applications in daily use of the average end user.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.

CSS centering absolutely positioned elements

 

CSS horizontal centering of an absolutely positioned element. Example: HTML / XHTML. Code: <div class="example"> <img src="image.jpg" alt="Image" /> </div> CSS. Code: .example {position: relative; left: 0px; top: 0px; height: 90px; width: 100%; float: left; padding: 10px; border: 1px #ccc solid; background: #fafafa; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -ms-box-sizing: border-box; box-sizing: border-box;} .example img {position: absolute; left: 0px; right: 0px; margin: 0px auto; width: 68px;} An absolutely positioned img is centered in the example. But this method of horizontal centering also works with other both inline and block absolutely positioned elements. The width of an absolutely positioned element may also be in percent or other units. CSS properties of a container (here it is .example), holding an element to be centered, may vary. The element's centering is achieved by styles applied to the element itself: .example img {position: absolute; left: 0px; right: 0px; margin: 0px auto;}.

Unzip multiple files. Linux

 

Unzip multiple zip files into one directory by Linux command line unzip. Contrary to possible expectations, "unzip *.zip" is not going to work, *.zip should be put into quotes: unzip "*.zip" There may be files with the same names in these archives. To avoid overwriting: unzip -B "*.zip" "Unzip -B" makes unzip to overwrite duplicates during extraction process, but saving a backup copy of each overwritten file. The names for these backup copy files are created by adding tilde ("~") at the end of the original names of the files. If a file extension is present, then "~" is added after it. If that is not enough, unique sequence number (up to 5 digits) is appended after the "~". "Unzip -B" is not too practical. For example, since when the sequence number range for numbered backup files gets exhausted (99999, or 65535 for 16-bit systems), the backup file with the maximum sequence number is deleted and replaced by the new backup version without notice ( More on the subject ). The number of files in an archive may not be always known in advance or may be more than possible sequence number range, so "Unzip -B" is not a great choice. Renaming duplicate files by adding "~" at the end of their names, after the extension, is not too convenient either. But another built-in option is even worse. If the "-B" modifier is not used, each time a file with same name as there already unpacked is being extracted, unzip asks "replace example.txt? [y]es, [n]o, [A]ll, [N]one, [r]ename:". And each time "r" must be hit, then a new name has to be input. So some bash or another script solving the problem should probably be prepared and used instead.
