问题
I've got such situation: I want to schedule a job with crontab on a linux server. I'm not super-user, so I'm editing (with crontab -l, editor vim) only my crontab file. For testing, I put there:
* * * * * echo asdf
And the job is not running. Is the restart of the server needed? Or maybe some administrator move?
回答1:
May be it is, cron jobs will run in their own shell. So you can't expect to see asdf on your console.
What you should try is
* * * * * echo asdf > somefile_in_your_home_directory_with_complete_path.log
Next check the file by doing a tail:
tail -f somefile_in_your_home_directory_with_complete_path.log
And if it's not, check if the cron daemon itself is running or is down:
# pgrep crond
OR
# service crond status
回答2:
For me * * * * * /bin/echo text > file is not working...I don't know why, previleges and everything is set.
(This command is running normaly when I execute it as the particular
root user, just to clarify this.)
This can be solved by injecting the path PATH=$PATH:/bin in my example.
Instead * * * * * echo text > file is working fine, probably path issue.
Hope I helped
