Answer Posted / bhaskar
To change permission on a file we can use chmod command.
Only thing to remember that to change a file permission one
must be the owner of that file or root in that system.
the typical format of chmod is
chmod <permissions> <filename(s)>
e.g. chmod +777 examplefile
The above command will provide read, write and execute
permission to all in the file examplename.
value for read is 4
write is 2
execute is 1
now to give all permissions it becomes 4+2+1=7
first digit refers to the permission of the owner.
second digit refers to the group permission and last digit
refers to permission to all
