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
