You can use the lsof command in ports, which will dig through the kernel's file name cache and print at least some names. FreeBSD 5.x's /proc/*/map does the same thing for you. If you use lsof, for any files missing filenames, you can try and find the name by running "find / -inum ####", where #### is the number in the NODE column. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
