for this purpose we need to use umask command...
as by default every file has default permissions of 666
and any directory have the dafault ermission of 777...

syntax: $ umask [umask options]
as it works with octal method only so
1 for execute
2 for write
4 for read
example:
$ umask
using umask alone will allow u to see the default permisions..
