These small commands are not so known, but i think they can do miracles for you when you have to work from the terminal on text files and you need to compare them, or do operation on lines inside 1 file or merge 2 files applying some criteria.
In this article I’ll show you the most common options for these commands and some practical examples on how to use them.
In general a file manager is a program that gives some kind of interface to the file system and that show in a graphical or textual way the files and directory, usually a file manager allow to do some standard operations such as delete, rename copy/paste and other typical operations that you can do on files.
Twin-panel file managers have obligatory connected panels where action in one panel results in a reaction in the second. So for example you could move a file from the first to the second panel, or copy it. In this roundup I‘ll show you some of the most used Twin-panel file manager available on Linux, sometimes they are also called Orthodox file managers or command-based file managers and in general they have three windows (two panels and one command line window).
Note: Konqueror supports multiple panels divided horizontally, vertically or both, but these panels do not act as twin panels by default (the user has to mark the panels he wants to act as twin-panels), so I’ll not put it in this article.
Thanks to Edmond, i’ve found a new and interesting online service shelr.tv.
Shelr.tv allows you to record something interesting from your terminal and share it to your followers.
It is almost the same thing as YouTube but for plain text shellcasts. You can copy and paste everything you see.
The nice thing is that you can play the shellcasts back directly on your terminal or in a browser from their website, and when uploading them you can decide to make them public or private. Continue reading »
Usually I’m not so precise and methodical and so I’ve never used a program of this type to keep track of my expenses, but the other day I wondered if Linux had some software in this category, and I was amazed by the variety and quality of software available for our beloved Penguin.
So here’s a roundup of the software in this category.

In my work I’ve not used “Expect” many times, but to do some jobs I’ve learnt how to use it, and I must say that to complete some tasks this program can help a lot and be a valid alternative to more complex solutions, like a complete program in python, php or your favorite scripting program.
But first a description of expect taken from his man page:
Expect is a program that “talks” to other interactive programs according to a script. Following the script, Expect knows what can be expected from a program and what the correct response should be. An interpreted language provides branching and high-level control structures to direct the dialogue. In addition, the user can take control and interact directly when desired, afterward returning control to the script.
In this article I’ll show you 2 examples on how to use it, to connect to a remote server via ssh and issue a command, to change the password of a user with the command passwd.
