A beginner's Guide to GIT command in Linux

GIT is a version control system, which maintains the versions of your code,(if you are a developer!) This Guide will help you to install git in linux, and commit your code in github.

How to install Git in linux
To install git in Linux, you need to run the below command in the terminal, open your terminal,

sudo apt-get install git

This command will install git in your linux machine.

Basic git command

After installing the git you need to setup the enviroment for git, for that you need to configure the git,

git config

Sets configuration values for your user name, email, gpg key, preferred diff algorithm, file formats and more. Example:

git config --global user.name "iGyan" 

git config --global user.email "iGyan.Org@Gmail.com" 

After configuring the git you need to make a branch tree for your code, for thet go to your code directory in terminal using and cd command and write.

git init

it Initializes a git repository and creates the initial ‘.git’ directory in a new or in an existing project.
now if you see the status of your branch using

git status 

to add the file in the branch you need to run add command like

git add

After adding the files you need to commit the code in your local system using

git commit -m ‘Added Some code’

here -m stands for the message, and in quoted string is your message.
And then you need to push the code to the repository of GIT like

git push https://github.com/iGyanCode/iGyan.git

after push you need to give a branch path which usually ends with *.git

Secure Mount Points in Unix

The primary way of interacting with a Unix machine is through its filesystem.
Thus, when an intruder has gained access to a system, it is desirable to
limit what he can do with the files available to him. One way to accomplish
this is with the use of restrictive mount options.
A mount option is a flag that controls how the file system may be accessed. It
is passed to the operating system kernel’s code when the file system is
brought online. Mount options can be used to prevent files from being interpreted
as device nodes, to disallow binaries from being executed, and to disallow the
SUID bit from taking effect (by using the nodev, noexec, and nosuid
flags). Files ystems can also be mounted read-only with the ro option.
These options are specified from the command line by running mount with
the -o flag. For example, if you have a separate partition for /tmp that is on
the third partition of your first IDE hard disk, you can mount with the
nodev, noexec, and nosuid flags, which are enabled by running the following
