Linux automatic cleanup log script sharing _linux Shell

1. A streamlined script for automating the deployment of systems, with the main function of cleaning up all directory logs

2. According to the given log directory, delete time combined with crontab to clean the log, clean up after completion, after the/var/log/deltelog/generated in the month of the cleanup log

3. Extension, because the script is Mtime (last modified time) to delete, so can be used to delete expired backups, and so on, not subject to file name restrictions

Shell Tips

Find–type F–print will be based on the line or space to output the search file, under different sh have different responses, if not done with Xargs to delete the change operation, will have an impact

So you need to add –print0 use NULL as a boundary symbol to get married. Xargs–o to format input

Use Find to follow the minimum result set principle, find analytic form left to right, all make sure that your leftmost filter symbol is able to filter the maximum data

You can add to the crontab according to your needs.

#find Log
echo "[' Date '] >> start delete logs---" >> $tmp _delete_log
Find ${in_log_path}-type f-mtime ${inner_num}-print0 | xargs-0 RM-RF
