rc.local file was—and in some cases still is—the place for Linux sysadmins to put commands that need to be run at startup. Use of the
file is not only deprecated but after a couple of hours worth of
attempts, was not working in any event. This despite the fact that the
systemd documentation mentions the use of a “generator” that generates
systemd services from an
rc.local file if one exists.
This tutorial creates a Raspberry Pi, a low cost single board computer, which can be used as a thin client that works with RDP, VMWare View, Citrix, OpenNX, and Spice. The base image for the OS is based on Debian.

Grep is a very important & powerful Linux commands. It stands for ‘Global Regular Expression Print’ & is used for matching & printing a search pattern or a regular expression from a single or multiple text files. It will look for the pattern if the mentioned files & will than print the result on screen or to an output file.
In this tutorial, we are going to learn to use grep command with examples. Continue reading “How to effectively use the GREP command”
This tutorial will walk through installation of OS for the the Raspberry Pi.
The Raspberry Pi will not start without a properly formatted SD Card, containing the bootloader and a suitable operating system. Most of the problems with booting the Raspberry Pi are a result of an improperly formatted or corrupted card. Make sure that you insert the card before powering on the Raspberry Pi, and that you shutdown the Raspberry Pi before unplugging the card.
First, you will also need to choose a distribution – the OS you want to for the Raspberry Pi. Note that you can have several SD Cards with a separate distribution on each, then power off, swap cards and restart the Raspberry Pi to use that card.

Most of the time, I’m using SSH to connect remotely with the Raspberry Pi. If you are more accustomed to a GUI, you can use VNC for remote access via the network. With VNC, you can access your Raspberry Pi’s GUI screen from a laptop or desktop computer using the same mouse, keyboard, and display of your own computer. Here’s the steps you need to do to setup a working VNC server/client to access your Raspberry Pi remotely. This is an tutorial done on Raspbian OS.
