I never thought there would be an "unset" command, so I } would have needed to read the entire man "page" (68 pages in the case } of bash), which is rather inefficient. I *did* scan it, but I thought } it would be quicker to ask. It was. You're just being lazy; I am certain your problem solving skills are really much better than that. Your original question mentioned that you wanted to unexport a variable; the string ``unexport'' occurs only once in the sh(1) manpage, and not coincidentally it's in the section you were seeking. Granted, ``unexport'' doesn't appear in the bash(1) manpage, but that's really the wrong place to look anyway. I was somewhat amused that not too long after asking your question, you went and RTFM'd wizkid11@xnet.com when he asked a question about a serial patch. I guess irony can be pretty ironic sometimes. -- Jon Hamilton hamilton@pobox.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
