sorry if this message in reply to the query regarding' chmod' is toomuch 
for some....

the command 'chmod' allows to specify the permission one (owner) can 
impose on self,group,and public  {u(ser),g(group,o(thers)} for the
following action
4   read only
2   write only
1   execute only   but no changes and no reading allowd
1+2  3   write and execute but not read
1+4  5   read and execute but can not changed
2+4  6   read write but not for execution
1+3+4 7   all three r w and e
(  unique 1-7 from 1 2 4) 

now the position of this number sets for different people
command is as follows
chmod     nnn   file   ( where nnn   000 to  777 each n from 0 to 7 
like 100 007   777 444 any thing like this) i think ' man chmod ' will tell
all this
