Crontab Generator

Cron jobs are basically scheduled tasks for Linux based OS, that are supposed to run at certain intervals, users can manually add cron jobs to their system by using the command crontab eand editing the file to add new cron job.

However not many people are familiar with the syntax of Crontab, to help them out there is a excellent service that will allow users to generate the syntax, by providing with a wizard interface.

You can use the wizard to get the syntax for the cron by inputting the command name and choosing the frequency you want to run it at.

crontab_generator

Once you have selected the settings, click on Create Crontab Line button, the service will automatically generate the syntax for the cron.

You can then copy the syntax and use the command crontab eto edit cron jobs and insert the new syntax. Can’t get any simpler than this.

Ubuntu Linux: How to Enable or Disable Swap Partition

In this post we shall discuss how to enable or disable swap partition in Ubuntu Linux. Ubuntu Linux or any Linux operating system can use a swap partition for paging in case if it runs out of physical memory. The swap partition is not a mandatory requirement for using Linux but it is advisable that you have a swap partition setup to avoid memory bottleneck in case you run out of your physical memory.

The aim of this post is explorer the ways in which we can enable or disable swap partitions it is assumed that you have already swap partition created during the Ubuntu Linux installation.

Method 1:

We can use Gparted partition manager to enable or disable a swap partition. If Gparted is not installed in your Ubuntu Linux then use the following command below to install it.

   1: sudo apt-get install gparted

This will install the Gparted partition editor which you can access from System>>Administration>>Partition Editor

screenshot-1

The Gparted will now display all the available partitions in the hard disk that is selected. In this case we have a 14.99GB hard disk that has got a swap partition of 682.42MB.

screenshot-2

To enable the Swap partition:

To enable the swap partitions right click on the swap partition and then select the Swapon’ option to enable the swap partition.

screenshot-3

To disable the Swap partition:

To disable the swap partitions right click on the swap partition and then select the Swapoff’ option to disable the swap partition.

Method 2:

In this method we shall discuss the enabling and disabling swap partition from terminal.

To enable the Swap partition:

To enable all the swap partitions on your computer you can use the following command.

   1: sudo swapon a

If you would like to enable the swap partition for a particular partition then you can use the following command:

   1: sudo swapon U <uuid>

To find the UUID of all the partitions use this command:

   1: sudo blkid

screenshot-5

In our example the UUID of our swap partition is 39be8652-da3d-4ad0-b11a-adb6c2ba3586 so the command will look like:

   1: sudo swapon U 39be8652-da3d-4ad0-b11a-adb6c2ba3586

To disable the Swap partition:

To disable all the swap partitions on your computer you can use the following command.

   1: sudo swapoff a

If you would like to disable the swap partition for a particular partition then you can use the following command:

   1: sudo swapoff U <uuid>

In our example the UUID of our swap partition is 39be8652-da3d-4ad0-b11a-adb6c2ba3586 so the command will look like:

   1: sudo swapoff U 39be8652-da3d-4ad0-b11a-adb6c2ba3586

That’s it you can enable or disable swap partition either using the Gparted GUI or using the command line.

How To Recall Typed Commands In Linux?

Download BOSS, The Indian Flavor of Linux

Just got a tweet about BOSS (Bharat Operating System Solutions) which is a Indian flavor of Linux developed by C-DAC (Centre for Development of Advanced Computing) for enhancing the use of Free/ Open Source Software throughout India.

This Indian GNU/Linux distribution is currently localized for Indian languages such as Hindi and Tamil.

The main aim of BOSS is to get more and more people and government organizations to use Open Source Software (OSS), we are sure that the localization of language should draw many users.

Kudos to the C-DAC team for coming up with BOSS. You can learn more and download BOSS here.
