The directory structure is certainly not the base to test whether a Unix-derivative is System 5 or not. In fact, the filesystem is the Journalling/Journalled File System (JFS) which does a good job of being different all by itself. >For example, try executing >the following commands on an RS/6000. > echo > This_is_a_long_filename > ls This* > od -c . >The output from 'ls' shows the long name, but the output from 'od' shows only >14 characters. Yes, I know. I opened a problem report about this a long time ago before GA. The reason this happens is that only the first 14 characters of a filename are stored in the directory with a pointer off to the rest. Since od just reads the parameter you give it, and won't spend it's time tracing pointers, the output you get from od is valid, it just *looks* System 5-ish. > | Email - !uunet!ulticorp!ultixrs!rick >Rick Poleshuck | Voice - (201) 887-9222 Ext. 755 > | Mail - The Ultimate Corporation, East Hanover, NJ 07936 jim/jsalter IBM AWD, Palo Alto T465/(415)855-4427 VNET: JSALTER at AUSVMQ Internet: ibmsupt!jsalter@uunet.uu.net UUCP: ..!uunet!ibmsupt!jsalter "Waco is a state of mind.
