cron doesn't run commands in /etc/crontab?
According to cron(8), cron should be able to read commands from a
properly formatted and chmoded /etc/crontab file. I've created such
a file, but I can't seem to get cron to run the test command in it.
# cat EOF /etc/crontab
*/1 * * * * /usr/bin/touch /tmp/crontest
EOF
# chmod 0600 /etc/crontab
cron then successfully loads the changes made to that file:
Mar 28 07:23:01 lass cron[11652]: (*system*) RELOAD (/etc/crontab)
I can also verify that the system file is loaded by watching the
output of `cron -x load`. The command is valid per crontab(5) and
works when inserted in root's tab using `crontab -e`.
After the system tab is reloaded, cron fails to run any commands
listed there: no CMD messages are logged (or seen in the debugging
output) and the file is never touched.
I've tried to get this to work on a semi-recent -current/i386 as
well as the latest snapshot (also i386) with no luck. I browsed the
code, but didn't see any obvious problems.
Any ideas?

Feel free to laugh if this is a stupid question, but have you made sure to leave an extra empty line at the end of the crontab? Are you in /var/cron/cron.allow ? Also, I usually pack everything into a script and then have cron call the script. It makes verbose comments and multi-line commands less obtrusive. -Lars Lars NoodC)n ([EMAIL PROTECTED]) Ensure access to your data now and in the future http://opendocumentfellowship.org/about_us/contribute On Wed, 28 Mar 2007, Will Maier wrote: According to cron(8), cron should be able to read commands from a properly formatted and chmoded /etc/crontab file.
