Subject: Re: Deleting directories in lisp From: Erik Naggum <email@example.com> Date: Sat, 22 Jun 2002 22:18:01 GMT Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * Paul D. Lathrop | I am writing some file-manipulation functions that I would find useful and I | have run into a problem I cannot seem to find a method of using lisp to | delete directories. I think you should not do that. I think it is a serious error for any user program to assume the role of administrator, even over files it has created. I am constantly annoyed by user programs that assume that I want to overwrite files. That is none of their business. If a file exists with the name they also want to use, it may still be important to me, and I would really like the user program not to delete its contents so I have to drag it back from a backup disk. With real file versions, this would never be a problem, but since Unix and Windows do not suppport file versions, the accidental loss of information they so strongly favor and cause is a major pain. So I think that if you want system administration tools, you should not look for help in the language, but in the system administration subsystem, and you should make a strong distinction between user program and administrators. Not so strong, of course, that you would need to do a serious change of identity, but strong enough that you do not accidentally lose or destroy information. -- Guide to non-spammers: If you want to send me a business proposal, please be specific and do not put "business proposal" in the Subject header.
