Another thing worth looking at: if something works from a shell, but not from cron, then you're probably not setting up the environment correctly in your crontab. An easy brute-force was to resolve this kind of thing is to have cron run a script that sets up the environment, then runs what you really wanted to run, instead of trying to figure out cron's slightly obtuse way of handline environment variables. cheers, Eric -- Eric Lennon Bowman BoboCo Ltd [EMAIL PROTECTED] http://www.boboco.ie/ebowman/pubkey.pgp +35317979094 -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
