Search and Replace Bash-Fu

2011-10-12T14:05:00.006+02:00

A little while ago I was searching for a tool that would allow me to perform multiple search and replace operations on multiple files. I didn't look very hard before it dawned on me that this could be quite an easy problem to solve using a simple bash script. It also smelled like a challenge, and I love a good challenge so this is what I came up with:What the script requires is that you provide a

Resetting Your Lost mySQL Root Password

2010-04-13T07:04:00.010+02:00

Ever forgotten your root password on a MySQL server? Or maybe you tried to change it and something went wrong. Now you're locked out of your own database. If you find yourself in this predicament, especially if you're a bit new to MySQL, you're probably panicking a bit right now; especially if you're working on a live database. Don't panic, and don't go doing anything drastic either; all is not

MS Office Communicator on Linux!

2009-06-23T09:18:00.003+02:00

One problem I've had since ditching Windows for Linux at work has been no support for MS Office Communicator in pidgin. None of the standard plugins did the trick, and installing the Microsoft client in CrossOver or wine also didn't work. Since convincing everyone else to change their chat protocol didn't really seem like a feasible option, I decided to just live without it... until this morning

PL/SQL Developer on Linux!

2009-05-14T13:37:00.004+02:00

Finding a decent SQL IDE for linux is not easy. I'm not a big toad fan, and even if I was, I don't think I could afford to be anyway... So what practical alternatives are there ? (aside from the Oracle Enterprise application suite itself of course). Tora seems to be the quick and easy answer, until you try to work using it ... Even Oracle's SQLDeveloper is cumbersome to use.Well I've always been

How to Run an X Server on Windows : An Introduction to Xming

2009-02-02T06:44:00.012+02:00

Accessing your Linux machine remotely is a no-brainer on the command line thanks to built in support for services such as telnet and ssh. But what about accessing your GUI remotely?Well on a Unix-based OS, it's pretty much just as easy, right out of the box. But thanks to great open-source software like Xming, it's just as easy from windows too. Before we get started we will have to download and

Access Your Linux Partitions In a Dual-Boot Environment

2009-01-20T10:50:00.012+02:00

If you're running Linux in a dual boot or multi boot environment, chances are good there's been times when you've needed to access some or other file on your Linux partition from within windows. Luckily there's an Ext2/3 file system driver available, for free.So you've taken the plunge and installed Linux, you've decided to be cautious and run a dual-boot environment; just to be safe in case you

Viewing Animated Gif's in Outlook 2007

2009-01-15T13:46:00.004+02:00

I use Outlook 2007 at work, basically because, well ... I don't have a choice. Since upgrading from 2003 to 2007, I've noticed that animated gif images (embedded) are not animated. I asked around, but it seems that everyone has the same problem, a google search revealed that there are loads of people in the same boat as me. The problem has been posted on forums all over the net.Here's a

UNIX: Nip That Elusive Backspace Key in the Bud! (3 ways to overcome an old, but annoying problem)

2009-01-13T21:24:00.003+02:00

The problem that I'm about to address is nothing new at all, in fact it's been around for yonks and is specifically related to running an old shell (such as ksh, sh or csh). It's amazing how easy it is to take the bash shell for granted, until you don't have it anymore.Yesterday I had the pleasure of being granted telnet access to our development server at my new job, an AIX boxen. Before then

Purging the Login Credentials Cache on XP

2009-01-12T11:20:00.006+02:00

One major annoyance that I have with Windows (when I'm forced to use it), is that it caches the login credentials you use when accessing a network share. So once you've entered credentials to access a share, windows will always re-use those credentials when accessing that machine (until you reboot of course).Fortunately there is a neat little trick you can use to get around this. By making use of

Upgrading your Ubuntu using the Command Line

2009-01-07T15:03:00.004+02:00

With the pace at which most major Linux distributions are releasing new versions these days, it's sometimes hard to stay up to date with the latest and greatest in your flavor of choice. Recently I upgraded my Ubuntu from Breezy Badger to Intrepid Ibex using the command line.Here are some step by step instructions to take you through the process.The first step is to get your current system up to

3G Mobile Broadband on Fedora Core 10

2009-01-06T10:54:00.007+02:00

Recently I decided to evaluate the latest release of Fedora Core. There is no doubt that Linux has improved exponentially as a desktop OS in the last few years, but I was really impressed with this release. The latest feature to really impress me is how easy they've made it to connect to the internet using a 3G mobile broadband connection.I've been connecting to the internet using mobile phones (

x2vnc : One keyboard (and mouse) to control them all ...

2009-01-04T22:37:00.005+02:00

So you need a windows machine (we're not going to go into why right now), in addition to your Linux box. The box in question is a complete physical box; but you discover it's becoming cumbersome managing two mice and keyboards on your desk. What you need is x2vnc.Install x2vnc.Using your distro's package manager, install x2vnc. For example, on ubuntu : sudo apt-get install x2vnc does the trick.

SSH Pre-Authorized Logins

2008-12-23T11:42:00.011+02:00

If you have multiple hosts which you access via ssh on a frequent basis, you may find that it's starting to become cumbersome having to constantly provide a password to log in. Fortunately there is an alternative, one which is extremely easy to configure too.Firstly, let's examine the contents of the ~/.ssh directory (~ being the linux shortcut for your home directory i.e. /home/{user}).
