In the past I’ve published some articles regarding how to download music from youtube with the program YouTube to MP3, or videos with the programs xVideoServiceThief and flareget, they all accomplish the work with graphical interfaces, and this can be a great plus for many users, but others could prefer a simple command line program that can easily download videos and optionally extract the audio in a specific format: youtube-dl.

Probably everyone that use a terminal know the command grep, from its man page:

grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus (-) is given as file name) for lines containing a match to the given PATTERN. By default, grep prints the matching lines.

So this is the best tool to search in big file for a specific pattern, or a specific process in the complete list of running processes, but it has a small limit, it searches for the exact string that you ask, and sometime it could be useful to do an “approximate” or “fuzzy” search.

For this goal the program agrep was firstly developed, from wikipedia we can see some detail of this software:

agrep (approximate grep) is a proprietary approximate string matching program, developed by Udi Manber and Sun Wu between 1988 and 1991, for use with the Unix operating system. It was later ported to OS/2, DOS, and Windows.

It selects the best-suited algorithm for the current query from a variety of the known fastest (built-in) string searching algorithms, including Manber and Wu’s bitap algorithm based on Levenshtein distances.

agrep is also the search engine in the indexer program GLIMPSE. agrep is free for private and non-commercial use only, and belongs to the University of Arizona.

So it’s closed source, but luckily there is an open source source alternative: tre-agrep

Many security policies require you to change the port number of the SSH service to ensure greater security in a Linux system. Situation now used throughout the IT world and used mostly by users who have their own private server. Today I want to show you how to add another security layer without having to change the SSH port. To do this we’ll incorporate the famous Google Authenticator to our ssh service, in this way we’ll have a safe, two steps security, by entering our password and the combination given from the GA application. Let’s see how to do this… Continue reading »

A few months ago I switched from Gentoo to Arch Linux as Linux distribution on my PC at work, and at the moment I am very happy with this distribution, but there is to say it is not so easiest to use for newcomers to the Linux world and so they typically approaches the most popular and user friendly Ubuntu.

Yo I’m Not Pro or Yoimnotpro center is a simple app center that allows you to graphically install some of the most common and useful packages available for this excellent distribution in a more simple way and therefore can help to bring some more users to this excellent distribution.
