spec - Local Sector 7 web page

while running spec will be copied elsewhere during installation, so the distributiondirectory need not be always accessible to the spec users. However, itisusuallyadvised to keep the distribution files available for reference. Youwill likely receiveupdated distributions from time to time, and it is a good idea to keep each distributionin a separate directory. The usual choice is to put the distribution in thespecadm home directory in a subdirectory named after the spec version number,such as ˜specadm/spec4.04.01.Decide where the installed files will go. Two directories are needed for the installedfiles. One is a directory for the executable programs. Most sites choose/usr/local/bin. This directory needs to be in each spec user ’s search path. The seconddirectory is for spec’s auxiliary files. The usual choice is /usr/local/lib/spec.d.Once these decisions are made and you have created a spec administrator useraccount (if used) and the directories mentioned above (if needed), you are ready toperform the installation. In brief, to install spec you:•extract the distribution from the supplied media or tar file,•run the installation program to install the spec files,•install optional kernel drivers (seldom necessary),•enter the hardware configuration for your particular experimental set-up.In addition to the information presented below, besure to consult any README filesin the spec distribution directories for up-to-date information on installation procedures.Extracting the DistributionIf you have made a spec administrator ’s account, you should become that user (orthe root user), either by logging in or by using the set-user id command su specadm .Youcan then change to the spec administrator ’s home directory and use it as a placeto hold the distribution files.Make a subdirectory to receive the current version of spec. Ifthe distribution isnumbered release 4.04.01, you might make a directory called spec4.04.01 using thecommand mkdir spec4.04.01 .Change to the new directory with cd spec4.04.01 .188 ADMINISTRATOR’S GUIDE INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION
