Schedule Your Jobs in Linux With CRON

Most of the Linux users are aware of how commands are run, processes are manipulated and scripts are executed in terminal. But, if you are a Linux system administrator, you might want them to start and execute automatically in the background. As an example, you might consider running a backup job every day, at a specific time, automatically. Or you might consider an example of collecting inventory data of the systems deployed across your network, by running a script automatically on monthly basis. But, how to schedule these jobs and execute them automatically in Linux?

    There is an utility in Linux known as CRON with which you can start your jobs automatically at a desired time and schedule them to get executed periodically.

    Cron utility consists of two parts: The cron daemon and the cron configuration files. Cron daemon is just like any service that is started automatically whenever your system boots. Cron configuration files hold the information of what to do and when to do. The main job of cron daemon is to inspect the configuration regularly (every minute to be more precise) and check if there is any job to be completed.

    In the /etc directory, you will find some sub-directories namely cron.hourly, cron.daily, cron.weekly and cron.monthly. You can put your scripts in these directories, and as their names suggest, they will be automatically executed after certain period of time. For example, if you wish to run a job or service regularly after every week, simple put the script in /etc/cron.weekly directory.

kmousetool and dragon naturally speaking for RSI

I'm currently using windows 7, but I am seriously thinking of switching over to linux.  Ubuntu seems like a good place to start and seems to be one of the most popular distributions.  Like a lot of people I'm becoming increasingly unhappy with windows, especially the support for XP ending, and the complete mess up of the start menu in windows 8.  I'm also looking at installing on my mother's 10 year old laptop, as that has really slowed down after the support ending for XP.  But my mother is not in any way technical like myself.

There are one or two sticking points for me though.  I have repetitive strain injury and currently use nib autoclick software.  I've been looking at kmousetool and managed to get left click right click and double click working OK, but can't seem to figure out the click and hold.  Also once I've got the programme started and running in the background, I can't get the settings up.  Do you have to leave the settings page open while you're using the program?  I would also like to know how easy it is to highlight text using the click and hold?

The second thing is using dragon naturally speaking in wine.  How easy is this to install?  Can the speech recognition be opened quickly and the text copied and pasted from the dragon pad in wine, to the main desktop environment?  I've had a look on the wine forum and version 10 seems to work the best.

Just one more thing when you install software that is outside the main software centre, like skype for example, does that slow things down and do any upgrades come from the software centre or would they come from skype?

Thank you for your help

Regards

Make Your Linux Machine a Virtual Router

I've written a boatload of Linux articles over the years. Not a big boat, mind you, but a boat nonetheless. Today, I'm going to tell you something important. Linux has reached a stellar of badassery and here's why. Not only do we get a free, open and customizable system, but we can also use our computer as a virtual router. Here's how:

 

1) Open terminal and type the following command

sudo add-apt-repository ppa:nilarimogard/webupd8

2) Now, type:
sudo apt-get update

3) Finally, we can install ap-hotspot
sudo apt-get install ap-hotspot

4) Configuration time, baby!
sudo ap-hotspot configure

If you're connected to an Ethernet cable, it should detect your network as something like etch0 -- just continue. Once it asks to name your network, name it something like awesomenetwork. Your WPA password should be of the following length (this is what I use as my password: fivefifty. No longer, no shorter. 

Here are a couple of commands to stop and start your router.

 

5) Start router

sudo ap-hotspot start

 

6) Stop router

sudo ap-hotspot stop

 

7) Restart router

sudo ap-hotspot restart
