Hi all,

I use centos7 and don't want to use tmpwatch as well as crond.

I have a question to use `systemd-tmpfiles-clean.service` with my custom configured file in `tmpfiles.d` to delete outdated files periodically in some log dir.

I have a `tmpfiles.d` configured file in `/etc/tmpfiles.d` named `my_log.conf` in following contents.

#Type  Path    Mode  UID   GID   Age   Arg
r /chenqiang 0775 root root 10s
r /chenqiang/test_10s
r /chenqiang/test_20s

If I run `systemd-tmpfiles --remove` with above configure, all files and dir will be deleted if I set 'r' type for the files and dir. but, I want to only delete some outdated files in the dir. and I use `systemd-tmpfiles --clean` with following configure.

#Type  Path    Mode  UID   GID   Age   Arg
d /chenqiang 0775 root root 10s
f /chenqiang/test_10s 0660 root root 10s
f /chenqiang/test_20s 0660 root root 20s

It can delete dir if the age > 10s, but can't delete the files in it.

So, would some one help me if I want to delete the outdated files ?

It can delete dir if the age > 10s, but can't delete the files in it. 

The man page for tmpfiles.d says, of the age field: "The age field only applies to lines starting with d, D, and x."

So, the line:

d /chenqiang/test_10s 0660 root root 10s

indicates that systemd-tmpfiles should create the directory /chenqiang/test_10s, owned by root/root with mode 0660, and periodically clean it of files and empty directories more than 10s old.

Note that the default configuration runs systemd-tmpfiles once per day, so specifying time periods much smaller than that may not be useful.
