How to insert a date inside the filename with logrotate
提问by Bernard Sfez
I need to set logrotate to rotate logs files from an application running on the server. I need the date inside the filename.
我需要设置 logrotate 以从服务器上运行的应用程序中旋转日志文件。我需要文件名中的日期。
I set dateext and also dateformat to add a - in the date. The result filename is:whatever.csv_2012-03-03
我设置了 dateext 和 dateformat 以在日期中添加 - 。结果文件名是：whatever.csv_2012-03-03
I would like the timestamp to be part of the filename keeping safe the extension; Whatever_2012-03-03.csv.
我希望时间戳成为文件名的一部分，以确保扩展名的安全；随便_2012-03-03.csv。

To insert the date within the filename (and not as extension) of a file under Linux while rotating a file it is correct to use:
要在 Linux 下的文件的文件名（而不是作为扩展名）中插入日期，同时旋转文件，正确使用：
# Daily rotation
daily
# We keep original file live
copytruncate
# Rotation is 1 so we have always .1 as extension
rotate 1
# If file is missing keep working
missingok
sharedscripts
postrotate
day=$(date +%Y-%m-%d)
mv blabla.csv.1 /var/www/gamelogs/dir/blabla$day.csv
endscript
}
This is simple and works fine.
这很简单并且工作正常。

You should be able to keep the extension apart, e.g. whatever.2012-03-03.csv, with the following configuration:
您应该能够将扩展分开，例如whatever.2012-03-03.csv，使用以下配置：
whatever.csv {
dateext
dateformat .%Y-%m-%d
extension .csv
...
}
Note the dateextis deliberately empty.
注意dateext是故意空的。
