Why cronjob fails to execute script in 'sh' shell in Red Hat Enterprise Linux 6?
Issue
- Our cron job uses 'tee' command to write some messages into the standard output and a log file.
- When it's defined as below, it stopped on the way to output messages into a log file.
20 21 * * * sh /root/test.sh
- But, when it's defined as below, all messages were output into the log file properly.
20 21 * * * sh /root/test.sh > /dev/null 2>&1
- Why it didn't work properly in the former case?
Environment
