Unzip multiple files. Linux

Operating systems : 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.

CSS centering floated elements

 

Centering an inline block containing several inline elements. The block is centered horizontally - [ Open demo page ]. Sometimes there is a need to have a centered group of floated elements, which is to serve as a title or a pagination box. Since this group of floated elements is going to be used as a title for content blocks of various dimensions or pagination box may grow or shrink in its size, then the width of the group of floated elements is to vary unpredictably as well. So a method of centering based on using a certain known width of the box is not going to work. And as an extra to the task there is a desirable condition: the title or pagination box has to be centered once and for all at the time of the box creation, so that this group of floated elements may be reused without any extra work over it: just place the complex where you need it and put the text or / and images you want to inside it - the group is centered anyway. This problem can be solved by several methods using several technologies: CSS, CSS + JavaScript, CSS + HTML (<table></table> tags system). The CSS centering floated elements is the most simple and reliable. So, here a pure CSS centering of floated elements is discussed. CSS centering floated elements: 1. First, a more simple case, css centering of a title box consisting of floated elements: images and text: HTML / XHTML.
