((i=0; i < 2; i=i+1)) should do the trick, regards, mathias duke@spacebox.net 2004-05-16 20:18:46 0000 I'm getting mail with the "kill" usage output: Usage: kill pid ... Send SIGTERM to every process listed. kill signal pid ... Send a signal to every process listed. kill -s signal pid ... Send a signal to every process listed. kill -l List all signal names. kill -L List all signal names in a nice table. kill -l signal Convert between signal numbers and names. I'm assuming it's because the lockfile doesn't exist, so in run-crons when it gets to the line if `kill -0 $cronpid >/dev/null 2>&1` $cronpid is empty, so kill outputs the usage info. But, shouldn't the line if test -f /var/spool/cron/lastrun/lock keep it from getting to that point without a pid? Is the problem I'm experiencing related to this bug? agriffis@gentoo.org 2004-05-24 20:55:37 0000 Ok, it's in portage as cronbase-0.3. And yes Duke, this should solve the problem you described. duke@spacebox.net 2004-05-24 20:58:46 0000 Thank you! 27641 2004-03-19 12:34 0000 new run-crons version run-crons text/plain
