instance method

File::Stat#mode

stat.mode → integer

static VALUE
rb_stat_mode(VALUE self)
{
    return UINT2NUM(ST2UINT(get_stat(self)->st_mode));
}

Returns an integer representing the permission bits of stat. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

Example

File.chmod(0644, "testfile")   #=> 1
s = File.stat("testfile")
sprintf("%o", s.mode)          #=> "100644"
