Hello All, I have to Rotate one of my log file (test\_cron.log) which is under /root/ on daily basis , so for that i have made one new file in under /etc/logrotate.d/soc\_logs. also added entry in crontab as : \*/1 \* \* \* \* /usr/sbin/logrotate /etc/logrotate.d/soc\_logs But it does not rotate daily. and write code as follows. /root/test\_cron.log { compress daily size 20k rotate 7 dateext create 0600 root root } Also i want 7 days backup of that log file and if file size increased by say for example 20k then also it must be make new file with date extension. Thanks in advance… Santosh… ---

If not, no rotation will happen unless you add ‘ifempty’. What happens if you call the command directly and add the --verbose switch so you can see evaluation as it happens? Post back here and we should be able to help analyze it. Also, your cron entry is redundant; \*/1 is the same as \*, so just go with - unless you have a great reason to do otherwise. Also, be sure your cron job is running as ‘root’; if you are properly using ‘crontab -e’ to setup the crontab entry, and are doing so as a non-root user, then that would impact this of course since a non-root user’s cron job would not have rights to do anything in /root by default. Finally, you should probably setup this logrotate definition under /etc/logrotate.d along with other files. This way you do not need a separate cron job. If you really want its own call via cron, then put your cron definition under /etc/cron.daily instead, rather than having your own cron job setup.
