Basic commands and comparision with windows functionality :-)

yup just installation is nt enough you want to learn something else to work on this platform so try these simple basic commands which is essential for even you become a big stream adm
in 


first let me write about some important terms that compared to windows
Directories  -  folders
root /          -  administrator


For a more details about that particular command  use the man pages available in the linux itelf .(eg: man ls)


1.COMMAND

• ls - To list the directory content -To list the contents of available directories

         

SYNTAX

                 -a -shows all files that are hidden (hidden files starts with .(dot))

                 -l  -shows all information with permission too

                 -r -reverse the order of file display

                 -s -gives size in blocks

                 -x -Displays files in columns

EXAMPLE

          ls  -l <directory name or file name>

     

   this command will display the files information with permission too

drwxr-----  2 root 4025 nov 8 19:51 mail/

in the above example first drwxr-----   is a permission lets we discuise about permission in new post just know about it d -directory r -read w -write x -execute

then 2 denote no.of directoris

4025 is size

and followed by date and time

mail/ is diretory name 

Comparing with windows

 ls command - in windows we open folders to view that files and we use folder option to view that hidden file orelse we use properties of that folder to view the permission and size and all but ina single command we can see all its :-)

2.COMMAND

• cd - Change directories - to move from one directory to another                                                          

                                                                                        

SYNTAX

                   cd <directory name> 

                  

EXAMPLE  

                      cd /home

in this if you are in root directory it will move on to /home directory 

Comparing with windows

                         cd command works as like that we use oru mouse and keyboard to choose or move from  one folder to another that will be done here by just typing 

3.COMMAND

• mkdir - make directory - to make a new directory                                                         

                                                                                        

SYNTAX

                   mkdir <directory name> 

                  

EXAMPLE  

                      mkdir /test

fr this command system will create a new directory  on  / -root's home directory

Comparing with windows

                         mkdir command works as like creating a new folder by right click on the mouse and selecting

     NEW - FOLDER(here in linux directories refers folder in windows nothing more than that)

4.COMMAND

• rm - Remove  - to remove a file

                      rm -rf  file1

in the first one rm file the command only remove the empty file 

while in the second one it will delete whole file even its written 

Comparing with windows

                       rm command works as deleting a files in the system

                      rmdir -rf test1

in the first one rmdir test the command only remove the empty directory if test directory has some other files inside it then it will prompt a message that the directory cannot be removed  while it has parent directory

while in the second one it doesn't prompt it will delete the whole tree structure 

Comparing with windows
