Best Linux Training Institute in Faridabad

Course Summary

Linux is very popular operating system in the world. If we want good security for the system, user, group, shared folder, file and some other thing then can plan for the linux operating system. Linux has many kind of the certification too, RHCSA, RHCE, Cloud, virtualization and etc. If we have some strong knowledge about the linux operating system then can also manage unix computer, can manage solaris system and other family of the unix.

Take some interesting example of linux, if we want to create multiple and blank files then can use following commands
# touch file1 file2 file3 file4 file5 file6 file7 file8 file9

Above commands use to create multiple and blank files, if we want to verify the command then can use below command
# ls or # ls –l

ls means listing and ls – l means long listing.
Take one other example of linux, if we want to create the user account then can create with following command
# useradd user1; useradd user2; useradd user3; useradd user4;

Four users has been created by the name of user1, user2, user3 and user4. Can execute multiple command with single line but definitely need to put ; for the separation. If we want to give the password then can use below command
# passwd user1; passwd user2; passwd user3; passwd user4;

There are seven console in linux operating system so can login multiple command with the help of single line.

I have given some interesting command and compare to other subject it is more interesting, means linux has zero percent theory. Means linux has no theory. If we want any certification from the red hat or GICSEH then will get two certificates. One from the GICSEH and other from the Red Hat exam. Redhat exam is based on lab completely. Means there is no any theory exam with linux operating system. Previous there was linux 7.0 but now linux 8.0 is running. If we have a plan to give the international exam then can give international exam on behalf of RHCSA and RHCE Module. Linux understanding level is different compare to other subjects or module. Linux need to start from RH1, means it is the first book of the red hat operating system, after the first book can move to the second book, RH2 then if both books will be over then can give RHCSA lab exam. In linux exam, first question will be like, they will give you one physical computer, in this physical computer there will be one virtual computer, so in virtual machine need to give the exam. If will discuss about the RHCE exam then they will provide one physical computer. In that physical computer there will be two virtual machine, actually for RHCSA need only one virtual machine but if will talk about RHCE then definitely we need two virtual machine. In the first question, they will give virtual computer but will not tell any password. First we need to break the password, once will be able to break the password then will be able to see the questions from the redhat. If will be able to not crack the password then will be not able to login the computer so in this case questions will not come to screen. If will compare with cisco and Microsoft then cisco has single choice question, multiple choice questions so can attempt the questions and will be able to clear the exam. There will be no any lab exam with entry level but cisco has many certification like CCNA, CCNP and CCIE. CCIE has completely lab exam. Actually CCIE has two exam, first will be based on theory and second will be based on the lab exam. If will talk about the red hat exam then red hat only lab exam no any theory exam.

Take one more example of redhat computer
If we want to create multiple folder then can create like below example
# mkdir dir1; mkdir dir2; mkdir dir3; mkdir dir4; mkdir dir5; mkdir dir6
Can verify the command via # ls –ld or simply can type ls command.

If we want to access from one computer to the other computer then there are many method. First will be the ssh with port number 22. Means easily can access from one computer to the other computer via ssh. There are telnet process too, with port number 23. Compare to telnet ssh is more secure because ssh has encryption security but telnet has direct access from the computer.
