In a former article i’ve show how to use Screen and Byobu, in short Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells) while Byobu is an elegant enhancement of the otherwise functional, plain, practical GNU Screen. Byobu includes an enhanced profile and configuration utilities for the GNU screen window manager, such as toggle-able system status notifications.

But today we’ll see something similar, but different: Tmux Continue reading »

This is my personal Top 8 of worst suggestions I’ve read, took or gave to other Linux users so far, feel free to add your as comment.

Legend: Q: Question, BA: The bad answer, GA : What could have been a good answer

1) Q: I have a file i can’t read/write/execute with the user i want!

Bad: “chmod 666 file” – This makes the file editable and destroyable by anyone.
Worse: “chmod 777 file” – This makes the file editable by anyone AND sets execute permissions for anyone. This means that any user can edit the file to do something malicious for the next user to (accidentally?) execute it.
Worst: “chmod 7777 file” – Also gives setuid and setgid permission. With this you’ve just given any user permission to fubar your machine, especially if the file is owned by root.

GA: Check which user and group have permission to do the operations you need on that file, subscribe the user to that group and/or change the owner or the group of that file. Continue reading »

As first thing i must say that I’ve never used this “line” of distributions, in the past when i wanted to use .rpm packages I used the Red Hat family Distributions, and then I moved to .deb distributions and Gentoo.

So It’s my first time with these 2 distributions, let’s see if Mageia has surpassed the “source distro”, or Mandriva it’s still leading in the Desktop.

A small intro of the 2 distributions (courtesy of Wikipedia)

Mageia is the name of a non-profit organization and Linux distribution. On September 18, 2010, a group of former Mandriva employees and community supporters announced that Mandriva Linux was being forked and a new, community-driven distribution would be created, called Mageia.

Mandriva S.A. is a publicly traded (symbol:MLMAN) Linux and open source software company with its headquarters in Paris, France and development center in Curitiba, Brazil. Mandriva, S.A. is the creator and maintainer of Mandriva Linux, describing itself as a “project initiator and a skills organizer in the Open Source arena”, and a founding member of the Desktop Linux Consortium.

Alias are a great tool to help increment your productivity on the terminal with bash (or any shell program you’re using), but usually we are too lazy to think at what are the most common, or long commands that we use frequently and prepare an alias for them.

And so someone has done a small piece of software to do this job: aliaser

Aliaser helps you identify frequently typed commands and creates bash aliases for them. Aliaser analyses your bash history and helps you identify commands that you use frequently.
