Securely share files between your computer and phone using samba

Introduction

In this tutorial, I am going to talk about samba and ufw services. If you limit your file share within a dedicated range of ip addresses in your local network, your files are generally secure (from outside access), and still able to share files.

Search your torrent directory using find command

Introduction

Often, when you browse a torrent site for your favorite Linux distribution, you might ask the question, have I already downloaded this torrent or not? One way to find out is to actually go into your torrent directory and search (by the way, new nautilus is pretty good at searching), but it is always good to have a script (that uses find command) to do that.

Open all your reddit subscriptions using a single command (alias)

Introduction

The alias command is considered both good and bad. It can sometimes simplify long and complex commands, but on the other hand it can also be misused to hide commands everyone could learn otherwise.

Long time Linux users have been using alias for many commands and scripts. Even the operating system itself uses alias for certain commands e.g ll for ls -alF, la for ls -A and so on. However, this tutorial is not going to be about simplifying existing commands, rather it is going to be about aliasing your reddit subscriptions.

Fix catalyst driver in Ubuntu 13.04

1. Introduction

I found lots of people struggling to get catalyst driver work in Ubuntu 13.04. This issue has been persistent for some laptops, ever since Ubuntu 13.04 came out, specially for Intel, AMD dual graphics setup. For people, who have been looking at catalyst drivers ever since http://ubuntuforums.org/showthread.php?t=1930450 post was published, should not be that hard to find the solution, but for those who are new to Linux, or don’t have time for these kinds of issues, this issue might be a show stopper bug. In this post I will try to reiterate the solution discussed at askubuntu.com.

Rename large list of files by removing just one character

Sometimes, we have a large collection of files e.g mp3 files that plays fine in a computer, but fails to copy to an external devices like a mobile phone, because of weird file naming. One of such cases happened to me, where all the files in a directory had pipe character (|) on them.

Those files would play fine on a computer, but failed to copy to a phone. Therefor,e I had to create following script to rename all those files, just by removing the pipe character(|). Here is the script (rename.sh).

for file in *.mp3
do
 rename 's/\|//' "$file"
done

I hope it helps someone.
