How to rename multiple files in LINUX/Windows 7/8/8.1

Renaming multiple files is always a hassle in any operating system, if done manually. It always proves to be a tedious job.

In this article, we present you some Bulk Renaming Utilities for both Windows and LINUX, which make renaming multiple files a breeze.


Bulk Rename Utility

Bulk Rename Utility is a great renaming tool that comes with multiple options - Use regular expressions, String replacement, Insertion/Deletion of String in the file name.

  1. Open Bulk Rename Utility.
  2. Select the folder which contains the files to be renamed.
  3. Then select the files to be renamed
  4. Now, enter the text which you want to replace in the file name in the Repl [3] group and then click on Rename

  5. String Replacement

    Adding Numeric Prefixes
  6. If you know a thing or two about Regular Expressions, then you can use Regex [1] group. (References section contains useful links to Regular Expression)
Rename using regular expressions



pyRenamer supports Pattern matching, Substitutions, Insert/Delete text in the file names. Although this one provides pattern matching, it is not as robust as regular expressions are. So this one will require you to write one hell of a pattern for long file names.

  1. Open pyRenamer. In the left pane, navigate to the directory that contains the files which are to be renamed
  2. Then click on the 'Substitutions' tab.
  3. Now enable the 'Replace' checkbox and enter the text to be replaced and the replacement text (you can leave it empty, if you just want to delete the text).
  4. Rename using text substitution
  5. Click on 'Rename'. The text in the file names will be replaced.
  6. If you know basic concepts about patterns or Regular Expressions, then you can go for 'Patterns' tab. pyRenamer does not use Regular Expressions, but instead uses its own pattern matching.
  7. Hover the mouse over the text fields to see the patterns offered by pyRenamer

4 Ways to Try LINUX without installing

LINUX is slowly gaining an upper hand in the Operating System market. But newbies do not want to straightaway install this "so called OS for nerds" (bull**it - LINUX has become much user friendly for beginners). They might want to try it out before installing it on their system. Also some LINUX users may want to try other LINUX distros before moving to any other LINUX distro
This tutorial aims at such people who wants to try any LINUX distro before installing it on their machine.

Possibilities :  

  1. Boot from Live DVD
  2. Boot from Live USB Stick
  3. Boot from ISO
  4. Trying it out from Virtual Machine

1. Boot from Live DVD :

This can be done by burning the ISO image of the LINUX distro you have downloaded to a DVD and booting from the Live DVD.
For burning the ISO file , you can use softwares like Nero, Power ISO, Ashampoo Burning Studio, etc.. under Windows
For burning the ISO under LINUX, you can use K3B, Brasero Disc Burner, etc

2. Boot from Live USB Stick :

This is the most popular option that everyone stick with. With this, you can even make your Live LINUX persistent (i.e. You can save files in them).
For this you need the LINUX distro ISO and software like Universal USB Installer, LiLi Boot ( for Windows) and UNetBootin ( for both Windows and LINUX)
Then open the software and select your distro as well as the USB drive from which you want to boot the GNU/LINUX distro.

3. Boot from ISO :

I have already made a post on How to Boot Ubuntu based GNU/LINUX distros directly from ISO file.

4. VirtualBox :

This method is obviously the first thing that pops out in anyone's mind who want to try out any new distro (Not just GNU/LINUX). There is no need to restart the PC unlike other methods. This is also the least time consuming process.

How to set default options for youtube-dl youtube downloader in GNU/LINUX

Before we begin, we shall see what exactly is youtube-dl, for those who might have stumbled upon this page accidentally.

What is youtube-dl ?

youtube-dl is a free command line utility that can be used to download videos from youtube (not just limited to youtube) in Windows and GNU/LINUX.

Linux Mascot Tux holding Youtube
Linux - Youtube

View the full list of sites supported by youtube-dl

Why should I set the default options ?

These are the benefits that I can come up with for myself :
  • Bandwidth is  saved
  • Prevent the video(s) from getting corrupted accidentally
  • Set you preferences for the video/audio format/quality
The benefits are not limited to the ones stated above.

Saving the bandwidth :

Problem :

Suppose that you have a limited bandwidth internet connection. You want to download some videos with youtube-dl , and only as moderate quality videos. Will you enter the options every time you paste a youtube link to download the video ? Sometimes you might forget to do so, and the youtube-dl might start downloading a HD quality video. Boom... Bandwidth loss for you.

Solution :

Set the default option to download the video in a particular quality or restrict the maximum size of the video file that can be downloaded

Prevent the video from getting corrupted accidentally :

Problem :

You start downloading a video and suddenly want to download the video in another format. You cancel the download and start the download. Unfortunately, if the new video is saved under the same file name, youtube-dl considers it as the same video being resumed and downloads from where the last video was stopped downloading. Result - Corrupted Video

Solution :

Set the saved video's file name to be VIDEO TITLE - VIDEO ID - FORMAT.EXTENSION . This could have saved my bandwidth and my time too. was out of luck

Prefer a Video/Audio Format/Quality Everytime :

Problem :

You may want to download the video/audio in a specific format/quality. But specifying them everytime will be a tiresome work.

Solution :

Set your preferred video/audio format so that you do not have to enter it everytime

Setting the default options for youtube-dl :

You can set the default options for youtube-dl in two ways: Graphical way or the nerdy command line way

Graphical way :

  1. Open the file manager.
  2. Open the .config directory in your home folder (If this is not visible, use Ctrl + H to make it visible)
  3. Open the file named youtube-dl.conf. If it does not exist, create one.
  4. Then enter the options that youtube-dl should take as default while downloading the videos. 
  5. Save the file.

Command Line :

  1. Open Terminal and enter the following :
  2. cd ~/.config/
    vi youtube-dl.conf
  3. Then enter the default options for the youtube-dl and then save the file
From the next time when you download the youtube videos using youtube-dl, the default options will take effect.

Download Videos without default settings :

Just as much you want to download using the default settings, you might also want to skip the default settings for some videos.

For you to download the video in the way you like, just add --ignore-config flag to the youtube-dl.

youtube-dl --ignore-config


If you just want to prevent a specific flag from taking effect, then you can also pass that flag with the value you want

Lets say, you have set the default video format to 18 (mp4 - 640x360), but you want to download a video in 720p webm format , you can pass the flag -f 247 .

How to open LINUX's Ext filesystem in windows xp/7/8/8.1

I have always mounted the NTFS and FAT partitions in GNU/LINUX, but never the other way around - mounting EXT partitions in Windows. Searching for the solution, I stumbled upon Ext2Fsd, a project that aims at mounting the Ext partitions in Windows.

Installing Ext2Fsd :

  1. Download Ext2Fsd
  2. While installing, it will ask for an option to whether provide the support for writing data to Ext partitions. If you wish to enable write access to your EXT partition, then you can enable the options ( Even if this option is not selected, I was still able to write to the partitions, so i am not sure what these options are for)

  3. After installation has finished, open Ext2 Volume Manager - this will be used to manage mounting the Ext partitions

Mounting EXT Partitions :

  1. Then select the Ext partition that you wish to mount in Windows. As a note, the Ext4 partitions are listed as Ext3 in the Ext2 Volume Manager, but no problems in mounting them.

  2. Ext2 Volume Manager

  3. Right click the partition and select 'Ext2 Management'
  4. A box will pop up presenting you with the options to mount the Ext partition

  5. Mounting options

  6. If you want to only mount the partition with any drive letter, you can use the first option 'Automatically mount via Ext2Mgr'
  7. If you want to mount the partition with specific drive letter every time, you can use the second option 'Mountpoint for fixed disk, need reboot'

Micromax Canvas Win W121: Top 5 features you need to know

Micromax has become quite a popular manufacturer in the past few years and the android operating system has been of great help. They launched various android devices that were powerful and offered excellent value for money. Now they are going beyond android and are making a move towards windows phone. They recently launched two new windows phone devices and they seem to be quite impressive. The smartphones are Canvas Win W121 and Canvas Win W092. The Win W092 is priced lower though the price of Win W121 is quite affordable as well. We take a look at some of the features of the Canvas Win W121.
Micromax Canvas Win W121

Impressive build quality
Micromax has really work on the quality of their devices in these years and this one doesn’t look or feel like a budget smartphone. It has got a slim profile with rounded corners that look nice. It features a metal frame which gives it a nice feel. The device is large with 5 inch display but it has been designed well so handling is not an issue here. You can easily hold and use the device using one hand only.
The device is light and the weight distribution is proper. This came as a relief as many earlier Micromax devices have been heavy in the upper half making them tough to handle. The back of this device feels premium as well due to the leather finish. There is no Micromax branding on the front face of the device and they have kept it to a minimum on the rear as well. The front has got three capacitive keys below the display and they haven’t gone for the virtual buttons like on Lumia 630. The volume button sits on left and power key on right of the device. There is no dedicated camera key.

HD display
The canvas Win W121 comes with an impressive HD display. It measures 5 inches and has a resolution of 720 x 1280 pixels. This gives you a pixel density of 294 pixels per inch. While this might not be a very impressive number for a mid-range device, for a budget device, it is. The display has got superb viewing angles and due to the high pixel density, it looks very crisp. The fonts look very clear and even the small texts are easily readable. The display does justice to the colourful interface of the windows phone. The contrast ratios are good so the blacks of windows phone look quite good as well. The colours are well saturated though they look a bit unnatural at times.

Decent hardware
We wanted to write powerful hardware here but suddenly we realised that they sell octa core devices for just a few thousands more. The hardware isn’t very powerful but it isn’t a slouch either. The Qualcomm Snapdragon 200 chipset runs a quad core processor clocked at 1.2 GHz. It gets the Adreno 302 GPU and has got 1 GB of RAM. It comes with 8 GB of internal storage and supports micro SD cards up to 32 GB. The hardware is pretty good to ensure smooth operation.
The Lumia 630 which is available at a slightly higher price tag is the closest rival for this device. It features a better chipset and GPU but gets half the amount of RAM. This limits the number of apps you can run on your device. With the Micromax Canvas Win W121, you won’t have to worry. You can run almost all the apps available on windows app store.
The device offers most of the connectivity options you would need. It supports 3G networks with speeds up to 21 Mbps, Wi-Fi, Bluetooth 4.0 and micro USB 2.0. The device comes with support for dual SIM. That is a rare feature on windows devices and saves you the trouble of carrying multiple devices. You can have two sets of messaging and call apps for each SIM card. This would give you individual call logs, messages and speed dials. In case you find this too complicated, you can switch to a unified system as well. You get the usual list of sensors like proximity sensor, gravity sensor, light sensor and accelerometer.
Budget devices rarely come with good cameras. Well this isn’t exactly the case here. This device has got a pretty decent 8 megapixel camera. The camera quality is quite good even when shooting indoors. The photos don’t turn grainy until the light goes very low. Outdoor shots are quite impressive and the colours are replicated well. You don’t find a flash or front camera on low end Nokia Lumia devices but here they have provided a LED flash and a 2 megapixel front camera. The front camera is not very impressive and the images you click are grainy.

Fresh Operating System
There are hardly any devices in the market right now that run the Windows Phone 8.1. This makes it quite an early player on this platform. While the operating system is very much similar to what we saw on the Lumia 630, you can’t have the Nokia Apps here. Thankfully they have decided not to add any of their domestic apps. You get Office 365 access on the device. For web browsing, you are short of options and would have to live with the Internet Explorer. Not that it is bad but we are so used to Chrome and Opera Mini that if feels a bit weird.

One thing that we surely missed here is the ‘Here Maps’. It is a Nokia app so you won’t be able to get it on this device. Nokia has got some other nice apps as well like the lenses. The app support is limited but you aren’t left out without the popular apps. Even the Instagram is here now after a long waiting. The experience of most of the apps is very different from their android counterparts and new users might take a while getting used to them.

How to create a system user in GNU/LINUX

Creating a system user in GNU/LINUX is a very easy task and now we are gonna see how to do it.

What is a System User ?

A System User is a user account that has no home directory or login options. So basically if you create a system user, it cannot be used to login into the system

See the video below for demonstration on what a system user is :

Why is it needed ?

System Users are generally created by softwares for their own needs. But in some cases, if you install a software, you may need to create different users for different purposes.

For example, when I installed IBM DB2, it asked me for different usernames for different purposes. But those usernames must be unique. So will you go creating a normal user (with a home directory and present at login) for that ? If you do so, you will have unwanted login users and home directories. The same goes for when the softwares create their own users.

In such cases all you need to do is create a system user.

How to create a system user ?

A system user can be created using the following command :

sudo adduser --system --no-create-home --disabled-login username
Now you can use this system user for samba sharing ,etc...
