=> We have several Operating Systems in the market
Ex : Windows, Linux, Mac, Solaris, Anroid, IOS
============
Windows OS
============
=> Developed By Microsoft company
=> It is GUI based OS
=> It is licensed OS
=> Single user based OS
=> Security features are less
Note: Anti Virus software we have to install.
=> Windows OS is recommended for personal use
Ex : watch movies, games, browsing, online classes
===========
Linux OS
===========
=> Developed by Linus Torvalds
=> It is free and open source
=> Linux supports both GUI and CLI
=> Linux is multi user based OS

===================
Linux Architecture
===================
1) Apps / Commands
2) Shell
3) Kernel
4) Hardware components
=> Shell is responsible to validate command given by user and translate that into kernel understandable format.
=> Kernel is one of the core component in linux os. Kernel is responsible to give instructions to hardware to process command execution.
====================
Linux File System
=====================
=> In linux os everything will be represented as file only.
/
/bin
/opt
/etc
/lib
/var
/mnt
/media
/home
Note: In Linux VM for every user one home directory will be available like below.
ec2-user : /home/ec2-user
ashok : /home/ashok
sita : /home/sita
================
Linux Commands
================
pwd: display present working directory.
cd : change directory
touch : create empty files
ls : listing the data of pwd
ls -l : long listing with alphabetical order
ls -lr : display files in reverse of alphabetical
ls -lt : display latest files on top
ls -ltr : display old files on top
ls -la : show hidden files also
mkdir : create new directory
rmdir : remove empty directory
rm : remove file
rm -rf : remove non-empty directories
cat : create file with data + append data + print data
cat > abc.txt
cat >> abc.txt
cat abc.txt
cat -n abc.txt
tac : print data from bottom to top
cp : copy one file to another file
mv : rename + move
history : display user activities in linux
head : display first 10 lines of the file.
head f1.txt
head -n 5 f1.txt
head -n 100 f1.txt
tail : display last 10 lines of the file.
tail f1.txt
tail -n 15 f1.txt
tail -n 50 app.log
tail -f app.log
=========================================
grep : global regular expression print
=========================================
=> It is used for searching data in the file
# print lines which contains ashokit keyword
grep 'ashokit' app.log
# print lines which contains ashokit keyword along with line numbers and ignore case sentivie
grep -n -i 'exception' app.log
# print lines which doesn't contains ashokit keyword
grep -v 'ashokit' app.log
# search for ashokit keyword in last 10 lines
tail app.log | grep 'ashokit'
# search for exception keyword in last 100 lines
tail -n 100 app.log | grep -n -i 'exception'
==========
vi editor
==========
=> It is used to edit the files in linux os
=> Using vi we can open existing files and we can create new files also.
$ vi java.txt
=> vi command works based on 3 modes
1) command mode (read data)
2) insert mode (press i in keyword)
3) esc mode (press esc key)
=> save and close (:wq + Enter)
=> close without saving (:q! + Enter)
=====================
Networking Commands
=====================
ifconfig : To check IP address of our machine
ping: To check connectivity
ping www.google.com
ping www.facebook.com
ping 172.31.4.278
wget: To download files from internet
wget
curl: To send Http request to server
curl https://reqres.in/api/users
================
User Management
================
-> Linux OS is a multi user based OS
-> Multiple Users can connect with linux vm at a time.
Note: When we create linux vm using "Amazon Linux" AMI we will get 'ec2-user' as a default user with sudo priviliges.
SUDO : Super user doing operation
# check users available
cat /etc/passwd
# create new user
Syntax : sudo useradd
Ex : sudo useradd john
# set password for user
Syntax : sudo passwd
Ex : sudo passwd john
================================
What is sudoers file in linux ?
================================
Note: To give sudo priviliges for the users we need to add them in sudoers file.
# open sudoers file
sudo visudo
Note: Configure user like below (just below root user)
john ALL=(ALL) ALL
smith ALL=(ALL) ALL
Note: After adding user, close that file using "CTRL + X + Y + Enter"
===================================================
How to enable password based authentication in linux ?
===================================================
=> In Linux VM by default PasswordAuthentication is disabled.
=> If we want to connect with Linux vm using username and password we need to enable that.
# open sshd_config file
sudo vi /etc/ssh/sshd_config
=> Find the Line containing ‘PasswordAuthentication’ parameter and change its value from ‘no’ to ‘yes’
Note: save that file and close it using :wq + Enter
# restart sshd service
sudo service sshd restart
# exit from the machine
exit
# connect with linux vm usng john user
# open gitbash
# execute ssh command
ssh john@public-ip
==================
File Permissions
==================
=> File permissions are divided into 3 types
a) read (r)
b) write (w)
c) execute (x)
=> File permissions will be represented like below
Ex : -rwxrwxrwx f1.txt
drwxrwxrwx ashokit
=> First 3 characters will represent owner permissions (the user who created that file)
=> Middle 3 characters will represent group permissions.
=> Last 3 characters will represent other users permissions.
Ex:
-rw-r-xr-x f1.txt
owner => read + write
group => read + execute
others => read + execute
-rwx------ f2.txt
owner : read + write + execute
group : Nothing
Others: Nothing
=> To add or remove file permissions we will use 'chmod' command.
# add execute permission for user(owner)
chmod u+x f1.txt
# remove write permission for user(owner)
chmod u-w f1.txt
# add write and execute permissions for group
chmod g+wx f1.txt
# remove read permission for others
chmod o-r f1.txt
=> We can represent file permissions using numeric numbers also.
0 => No Permissions
1 => Execute
2 => Write
3 => (2+1) => Write + Execute
4 => Read
5 => (4+1) => Read + Execute
6 => (4+2) => Read + Write
7 => (4+2+1) => Read + Write + Execute
# user-read, group-write, others- r+e
chmod 425 f1.txt
# u+rw, g+w, o+we
chmod 623 f1.txt
#u-rwx, g-rwx , o+rwx
chmod 7 f1.txt
#u-rwx, g+rwx , o+rwx
chmod 77 f1.txt
======================================
How to change ownership of the file ?
======================================
=> using chown command we can change ownership
$ sudo chown ashok f1.txt
==================
Package Managers
==================
Package : A software
=> Package managers are used to manage softwares installation in linux machines.
=> Package Managers are specific to linux distribution.
yum : amazon linux, cent os
apt : ubuntu , debian
rpm : red hat
