That arbitrary number works simply because kern.argmax default has been raised somewhere in 6.x (before it was 64kB). % echo `sysctl -n kern.argmax`/1000|bc 262 And MAXNAMLEN in sys/dirent.h is 255. Knowing your way around maximum arguments length through xargs as suggested in this thread is much better solution then trying to exercise control over directory sizes, which may or not be under your control in the first place. -- Mel _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
