A database server, there are a large number of Crontab scheduling.

After each run, an email is sent. Over time, I am afraid that a large number of e-mails will take up inode, resulting in inode exhaustion.

View the mail directory

/ var/spool/postfix/maildrop

Use df-I to view the usage of inode.

Stat can view the inode information of a file

Although the usage rate is less than 1%, crontab always sends emails to report results, which is always a boring thing.

You can disable a schedule to send mail

* job & > / dev/null

Or set mailto in the crontab script to disable all tasks from sending mail

Crontab-e

MAILTO= ""

* / home/test/unison.sh > > / home/test/unison-run.log 2 > & 1

Many file names contain special characters and are difficult to delete

You can also use inode to delete

Use ls-I to get the inode number of the file, and then delete
