Thank you, but I would prefer to avoid any external script.

I finally found the correct way, as I had to remove everything (lucky
all are files) except the one sub directory:

ExecStartPre=/usr/bin/find ${REPORTDIR} -mindepth 1 -type f -delete

OK. I understand now.

In my case, there is one more hurdle. Will post elsewhere as it is OT
in this list.
Thank you for your help.

ExecStart does not go through a shell, so it won't expand wildcards.

Try running 'find /dir -mindepth 1 -delete', that also cleans up dotdirs.

Alternatively 'sh -c "rm .../*" to handle wildcards.

[systemd-devel] empty a directory in service file as ExecStartPre

2016-01-02 Thread arnaud gaboury 
I can't manage to empty a directory as a Exec in a service file. Here is part:

---
[Service]
User=postgres
Environment=REPORTDIR=/storage/psqlReport
ExecStartPre=/usr/bin/rm -f ${REPORTDIR}/*
ExecStart=MyCommand

--

$ journalctl -xe -l
---
-- Unit pgcluu_collectd.service has begun starting up.

Jan 02 12:34:02 poppy systemd[1]: pgcluu_collectd.service: Control

-

Running manually the rm command as user postgres empty the directory,
but when in service file, the directory is still full. I see it as
ExecStart=MyCommand complains the directory is full and service exits
with an error.
User postgres has of course rw access to directory content.
No any kind of interactive prompt when running rm.
If I start the service with an empty /storage/psqlReport, service success.

What am I missing? Is there a better way to empty the directory before
running my command ? The service will be timered, so can't empty
manually.

Thank you for help.
