Redhat – Rysnc Dynamic Log File Name

cronredhatrsync

I am setting up rsync cron to run every hour to sync up 2 servers. My question is how do I make the log file name that it is saving to in the format log_file-{Year}-{Month}-{Date}.log with the year, month, and date changing accordingly?

Thanks in advance.

I assume you're using --log-file? Then you can do something like this:

date=`date +%Y-%m-%d`
rsync --log-file=log_file-$date (...)

Or, in a single line if you're putting this directly in your crontab:

rsync --log-file=log_file-`date +%Y-%m-%d` (...)

Try:

0 0 * * * /some/path/to/a/file.php > $HOME/`date +\%Y\%m\%d\%H\%M\%S`-cron.log 2>&1

Play around with the date format, if you like; just be sure to escape any % like \%, as above.

By default, cron mails you the output messages of a cronjob. More specifically, it saves stdout (standard output) and stderr (standard error output) of a cronjob and emails it the owner of the crontab, or the user named in the MAILTO variable in the crontab.

To prevent output reaching you, you have to make sure that stdout and stderr is not saved, but written to a file or /dev/null.

You can do this by using something like this in your job definition:

job.sh > /dev/null 2>&1

This redirects stdout to /dev/null (the '> /dev/null' part) and redirects stderr to stdout, and thus to /dev/null, too (the '2>&1' part). Odd syntax, right? ;-)

The Advanced Bash Scripting Guide has a lot more information about I/O redirection.

Alternatively, you can leave MAILTO empty (that is, define MAILTO="" in your crontab) and you will not get any mail, according to vixie-cron's manpage on RHEL4 and RHEL5.
