by default command arguments


Is the command cp in bash is by default set on --preserve ?

No.
In bash you can define a function
Code:
cp(){
command cp --preserve "$@"
}
then a simple cp will be like that.

see man cp:
Code:
       --preserve[=ATTR_LIST]
              preserve the specified attributes (default: mode,ownership,timestamps), if possible additional attributes:  context,
              links, xattr, all

I do not really understand.
The manual system [1]there are two mutually exclusive options: --preserve and --no-preserve. Logic suggests that one of option must be the default.

the default what is written as default and is highlighted in my previous post:
(default: mode,ownership,timestamps)
so by default these attributes are preserved, others are not.

As pointed out by pan64, your assumption is wrong as there are some default options preserved but not all, so --preserve allows you to preserve more than the default and --no-preserve allows you to remove all that may have been preserved, either by default or a previous setting.
