I currently only have a 1-liner in the presentation. But, I was planning on showing the attendees how to view things like /proc/cpuinfo and /proc/meminfo. My audience consists of a few PHD/actuaries who just need to be able to use Unix and Linux to run various products. The do, however, have VMWare Workstation installed on their systems with a Linux VM guest. I'm not sure if the guest is Ubuntu or RHEL 4. They all have logins to various corporate Linux and Solaris systems. -- Jerry Feldman <[EMAIL PROTECTED]> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
