Fix vnStat Not Automatically Updating

There was a problem for me after publishing the vnStat PHP article, it's vnStat console could not update its database automatically. The result was vnStat PHP cannot update the data automatically as well. The cause is probably because I accidentally ran vnstat update as root. But apparently the solution is easy. Just make the user of vnstatd daemon the owner of the database directory.

10 Easy Examples of GNU sed Command Lines

GNU sed (stream editor) is a clone of UNIX sed command line program from GNU operating system. GNU sed is almost always included in every GNU/Linux distribution (e.g. Ubuntu). While the most of computer users edit a text file only with a real time text editor like Notepad, UNIX family users can edit a text file by a stream editor like sed. This article gives you the examples of stream editing for text file(s) with GNU sed. Because of it is GNU sed it is universal, so if you don't use Ubuntu (but at least you use any GNU/Linux distro), you can practice all of these command lines correctly. If you use another family of sed (e.g. UNIX or BSD one), probably you will need to adapt some commands because they have some differences.
