In this tutorial we will use CH341A programmer to read, write and erase data/firmware on attached chip. This is your getting started guide to CH341A programmer. CH341A programmer allows users to attach variety of chips in order to read or backup firmware or overwrite the exiting firmware.
The Bash shell is one of the most powerful components of a Linux system, as well as one of the most compelling reasons to use Linux. Users can interact with Bash through the command line, and write scripts to automate tasks. Although this may sound intimidating to beginning users, it is not hard to get started with Bash scripting.
There are many different text editor choices for a Linux system. Your choice of which text editor to use will depend on the type of work you plan on doing. For example, writing basic documents vs. coding websites or programs. Whatever your case, there are a lot of nice text editors available.
The purpose of this tutorial is to show various methods on how to rename or replace white space in multiple files. Some tools on a Linux system may not work properly with files that contain white spaces, which would give some users motivation to replace the white space with underscores, for example. Manipulating files without white space is much easier, as you do not have to worry about escaping the file name each time.
The purpose of this tutorial is to show how to extract a number from a string using Bash – that is, either in a Bash script or from the Linux command line. It is common to use Bash as a utility to process strings or other textual data, so it is well equipped for the task of separating numbers out of a string. There are numerous ways to achieve this; see some of the examples below to get started.
Neither Python nor Git need presentations: the former is one of the most used general-purpose programming language; the latter is probably the most used version control system in the world, created by Linus Torvalds himself. Normally, we interact with git repositories using the git binary; when we need to work with them using Python, instead, we can use the GitPython library.
In this tutorial, we will provide a few Bash scripts to scan and monitor the network using combination of commands such as
ping. Obviously, these scripts are no match to a full monitoring dedicated software like nagios, but they could be useful for small home brand networks, where implementing sophisticated monitoring systems can become too much overhead.
This tutorial is intended for all programing enthusiasts on all levels that wish to understand pointers in the C++ language. All code presented here is not compiler-specific, and all examples will be written in plain ANSI C++. Debates about pointers can stretch for miles, and you would need to go really far to master it all.
After reading this short shell scripting tutorial, you will be able to to create and execute your own Bash shell script. No previous knowledge of shell scripting is required. However, you are expected to have some knowledge of how to start a command line terminal and how to edit text files with some text editor of your choice.
Is it best practice to include usage in every Bash script that you create. This gives the user an idea of what options the script is expecting, so they can use it as intended. It also gives the script some error checking ability to make sure that the user has supplied arguments in the expected way.
