Values of environment variable could be the default editor that will be used, for example, the location of all files that can be executed in the system or local settings for the system. Beginners of Linux will find this a little difficult but the environment variable is an excellent way of sharing the configuration settings between several applications and processes.
In this tutorial, we will show you, how to use the Ubuntu crontab. In a few simple steps, we will explain, how to automate your system tasks on Ubuntu, using the crontab in Ubuntu. The cron software utility is a time-based job scheduler in Unix-like operating systems. Cron is driven by a crontab (cron table) file, a configuration file that specifies shell commands to run periodically on a given schedule. The crontab files are stored where the lists of jobs and other instructions to the cron daemon are kept. Users can have their own individual crontab files and often there is a system-wide crontab file (usually in /etc or a subdirectory of /etc) that only system administrators can edit.
Ubuntu and Debian both use packages to add to the system’s capabilities, allowing users to do more with their machines. …
Jekyll is Ruby based, free and easy to use site generator, designed for creating static blogs, but it can be also used for creating all types of static websites as well, without using a database. Jekyll works by processing plain text files in Markdown and Textfile or Liquid templates and generating static website. This kind of websites have many advantages over the dynamic sites, such as security, speed and flexibility. Websites generated with Jekyll can be hosted on any type of web server or GitHub. In this tutorial we will cover the installation of Jekyll on a CentOS 7 VPS.
Buildbot is a continuous integration tool based on Python which automates the build, test and release software cycles. It is built using the Twisted networking engine, supports parallel execution of jobs across multiple platforms and it is compatible with all major operating systems. The Buildbot installation can have one or more masters and number of workers. In this tutorial, we will show you how to install Buildbot master and worker on a CentOS VPS.
