o It's needed for the proper operation of the file(1) command; perhaps others. o It's unlikely to be modified by an installation.

Is its operation automated, even to the minimal extent of copying from /samples any _essential_ members (such as magic) not otherwise present in /etc? Did my systems programmer overlook a highly recommended health checker step?

The UNIX ad-hoc convention of a colon-separated list of directories is less orderly and less uniformly available than the OS facility of a concatenation of directories with a search order intrinsic to the system. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
