Message-ID: <6082@orstcs.CS.ORST.EDU> Date: 19 Aug 88 00:47:26 GMT Reply-To: ruffwork@CS.ORST.EDU (Ritchey Ruff) Organization: CS Dept, Oregon State University, Corvallis Lines: 14 What I need is a way to make a file act sort of like a tape loop or a shift register. I have a log file for a program that will quickly grow to consume all of disk. I really need the last 100k or so in case it dies or loops, but anything older than that can be trashed. Basically I need a file to act like a buffer and I need reliability (if the machine or process dies I *need* to have that last 100k--or whatever--but I don't need to 45M I normally get now ;-). Seems this would be usefull for things like the /usr/adm/*log's, the sendmail log, the uucp log, etc. That's why I'm asking before I go write it myself...anyone done it already (I'm using 4.[2,3] BSD) ??? thanks in advance, --ritchey ruff ruffwork@cs.orst.edu -or- ...!tektronix!orstcs!ruffwork
