Three types of permission read write and execute, Ever file and folder have three relations owner group and


others


 


 


[ Read = r write = w execute = x ] [ owner = u group = g other = o ] 


[root@pc1  ~] #  Ls  -Ld  /disk 



 


1= nature of object [d=dir -=file L=link] 


2= first three permission for owner [ rwx ] 


3= second three permission for group members [ r-x] 


4= third three permission for others [r-x] 


5= number of inodes contain by this directory 


6= owner of directory 


7= group of directory 


8= size of directory 


9= creating date of object 


10= name of object 


 [root@pc1  ~] #   Ls  -L  /disk


Drwxr-xr – x   2   root   root   4096   Jan   1   1988   dir1


Drwxr-xr – x   2   root   root   4096   Jan   1   1988   dir2


Drwxr-xr – x   2   root   root   4096   Jan   1   1988   dir3


Changing permission = give write permission to other on /disk


[root@pc1  ~] #   chmod  0+w  /disk


Give read write and execute permission for group on /disk


[root@pc1  ~] #   chmod  g+rwx  /disk 


Assigning read writ and execute permission to user, group and other with single command


[root@pc1  ~] #   chmod    u+rwx , g+rwx, o – rwx  /disk 


Assigning different permission with different commands which separate with semicolon


[root@pc1  ~] #   chmod   u+rwx   /disk  ;  chmod  g+rwx   /disk  ;  chmod  0+rx  /disk 


Using number system =----- [ Read = 4 ] [ Write = 2 ] [ Execute = 1 ]


rwx=7


r-x=5


---=0 


Assigning full permission to owner and no permission for group and others


[root@pc1  ~] #   chmod  700 /disk 


Assigning full permission for owner and group no permission for other


[root@pc1  ~] #   chmod  700 /disk 


Assigning full permission to all


[root@pc1  ~] #   chmod  777 /disk 


Assigning full permission for owner and read, and execute for group and others


[root@pc1  ~] #   chmod  755 /disk 


Assigning no permission for all


[root@pc1  ~] #   chmod  000 /disk 


Assigning sticky bit permission for other


[root@pc1  ~] #   chmod  o+t   /disk 


Assigning suid permission for owner


[root@pc1  ~] #   chmod  u+s  /disk 


Assigning sgid permission for group


[root@pc1  ~] #   chmod  g+s  /disk
