Thinks to reply (very fast :D)

I think it's may dangerous because generally system command should be
highter older then user's command.

For example , some guy put a "rm" but named "ls" to ~/bin . This "ls"
can be virus or ransomware , user may not know it's not which he
want("ls").

So I think put ~/bin to tail of $PATH has better security for normal user.

For me, I will avoid use same name with exist command, and for user
who want use same name , I believe he know or will learn how to modify
$PATH.


I mean , put ~/bin in tail of $PATH will batter for default setting,
so does developer has another reason to put to beginning ?
