Hi, Please take a look at the following cron task:
* * * * * root ps -eaf | grep -E 'cdrecord.* -[dts]ao |cdrdao *write|growisofs.*speed=' > /dev/null || logger get executed. It bewilders me that it is not doing what I want. Here is the syslog when it is run: Mar 15 13:15:02 cxmr /USR/SBIN/CRON[22779]: (root) CMD (ps -eaf | grep -E 'cdrecord.* -[dts]ao |cdrdao *write|growisofs.*speed=' > /dev/null || logger get executed.) Mar 15 13:15:02 cxmr /USR/SBIN/CRON[22780]: (root) CMD ... I.e., I want to execute a cron task if I'm not burning CD/DVD. But the actual command never get executed, even when I'm not burning CD/DVD. If I redo the command from the command line, it is fine: $ (ps -eaf | grep -E 'cdrecord.* -[dts]ao |cdrdao *write|growisofs.*speed=' > /dev/null || logger get executed.) $ tail /var/log/syslog Mar 15 13:16:27 cxmr tong: get executed. So, what is the problem? PS. I'm sure the PATH is setup properly in my cron, so cron can find ps & grep.
