Basic Commands Of Linux With Examples

This is my whatsapp no if you have any queries ping me up! :)

In this blog, I will be describing a few Linux basic commands that are often used in the daily life.

The commands that we are going to cover in this blog are

• 

  Terminal.

  cal --------> calender
• date --------> current time and date
• cd --------> change director
• mv --------> move
• rm --------> remove
• rmdir --------> remove directory (empty){cannot del non-empty dir}
• man --------> manual
• mkdir --------> make directory
• touch --------> create empty file  
• history --------> history of commands
  Always remember, in Linux case (upper case & lower case) does matter.
  leo@nemesis:~$
  1 2 3
  1--->account name
  2--->hostname of the computer name(computer name)
  3---->user is without root privilege
  
  
  If root is like adminstrator account in windows. In linux, root account has access to manipulate any file.

   So, starting with the execution of commands on the terminal
   {comamnds are written after $ or # symbol.}
  
  
  1)cal
  leo@nemesis:~$ cal
  
  
  
  
  
  
  
  2)date
  leo@nemesis:~$ date
  Wed Aug 15 10:51:45 IST 2018
  
  
  3)cd
  In Linux there are no drives (unlike windows having C, D, E drives), there is only files and folders.
  like in windows " C:/ " is the main drive, Linux we have " / ".
  
  
  leo@nemesis:~$ cd /home/ opening "/home" on terminal
  leo@nemesis:/home$
  
  
  4)mv
  leo@nemesis:~$ mv ./Pictures/linux.png ./Downloads/
   
  Above command is moving the linux.png file to Downloads. In Linux " . " is used for the current directory.
  
  
  5)rm 
  
  leo@nemesis:~$ rm linux.png 
  
  removing the file named linux.png

  Try the other remaining commands.
