Subject: Linux Administrator                                                      Exp No.   3

 

Aim of the Experiment: To know and practice of Basic Linux Commands

 

 

Software Required:

1.     VMware

2.     Rhel 7.0

 

 

 

 

 

Theory:   

                        Basic Linux Commands: Commands are some format of texts, through which one can access the things and, can do whatever he wants without visiting in different directories, or interfaces. He can do his all works form one particular place/interface, in Linux that particular interface is called Terminal, from where one can do his all works just by giving commands (texting).

 

 

Implementation/Steps:

                        First, i started the virtual machine.

                        Then in the Terminal I did practice with commands.

                        Such as:

                                    #date      (To know current date and Time)

                                    #cal        (To get current calendar)

                                     #cd       (To go to current user’s Home directory ‘/root’)

                                    #pwd       (To list the user’s current working directory)

                                   #cd -       (To return user’s previous working directory)

#cd ..       (To return one step back from present working directory)

#cd ../..    (To return two step back from present working directory)

#cd --       (To go to current user’s Home directory ‘/root’)

#ls            (To list the contents in a directory)

#touch      (To create an empty text file)

#mkdir     (To create an empty directory)

#rmdir     (To remove an non-empty directory)

#rm          (To remove an text file)

#rm –r      (To remove a directory recursively)

#clear       (To clear the contents from Terminal)

 

Conclusion:

                        Now I’ve familiar with basic commands of Linux.
