Your problem may be that in some Unix implementations, the first thing cron does is setuid(1); which means it (and its children) probably doesn't have permission to write in any log files you might be trying to use to leave tracks. I've found that removing the setuid makes cron much more useful. -- Larry Campbell decvax!genrad The Boston Software Works, Inc. \ 120 Fulton St. seismo!harvard!wjh12!maynard!campbell Boston MA 02109 / / ihnp4 cbosgd ARPA: campbell%maynard.uucp@harvard.arpa Brought to you by Super Global Mega Corp .com
