invoking $file < /dev/null does probably not play too well with [ -t 0 ] tests to determine whether the script is being invoked from cron. One would assume that it's one of the /etc/periodic scripts that's sleeping. Interestingly, # grep -lri sleep . ./daily/480.leapfile-ntpd and given my daily_ntpd_leapfile_enable=NO, that shouldn't be doing anything. So let's look at /usr/local/etc/periodic : # grep -lri sleep . ./security/410.pkg-audit and indeed there we can see (L59+): # Random delay so the mirrors do not get slammed when run by periodic(8) if [ ! -t 0 ]; then sleep `jot -r 1 0 3600` fi As we've seen above, this script gets invoked with < /dev/null > tempfile, so [ -t 0 ] will always be false. But when being invoked from the terminal, one shouldn't sleep randomly. It doesn't make sense. The invocation time itself is random already, we're not coming from a cron ran periodic incantation. -- You are receiving this mail because: You are the assignee for the bug.
