Help! (PC) Message-ID: <0010.9011201348.AA00696@ubu.cert.sei.cmu.edu> Date: 20 Nov 90 05:36:18 GMT Sender: Virus Discussion List Lines: 16 Approved: krvw@sei.cmu.edu rem@cs.bu.edu wants to know if the files which show up when he does dir | more are a virus? No, they are evidence of the difference between Unix and MSDOS. The "|" is a "pipe" between two programs, passing the output of one into the input of the other. In Unix, the pipe is handled somewhere inside the system; in MSDOS, it is handled by re-directing the output into a temporary file and then re-directing the temporary file into the next program. Unfortunately, MSDOS has a tendency to leave the temporary files lying around. This is especially true if you abort the more output with a ^C. When you own a dog, you have to be prepared to use a "pooper-scooper" occasionally! Art Larky alarky@scarecrow.csee.lehigh.edu alarky@aragorn.csee.lehigh.edu Disclaimers re:Lehigh University apply.
