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 ?
