Delete old backups shell command error

[tom_l]

Still not deleting old files.

This works fine via ssh: find /backup/* -mtime +30 -exec rm {} +

But trying to run it as a shell command:

delete_old_snapshots: find /backup/* -mtime +30 -exec rm {} +

fails with

2018-09-26 01:15:11 ERROR (MainThread) [homeassistant.components.shell_command] Error running command: find /backup/* -mtime +30 -exec rm {} +, return code: 1
NoneType: None

I can only assume it is some sort of permissions thing.

My hassio build is down atm as I’m moving over to a small desktop ubuntu machine so I can’t test it. There must be a way to add the permissions needed by rm, but I don’t know them

I think I worked it out…
See this thread:

Shell_command in HASSIO

I had a similar issue. I can run this in ssh: /usr/bin/mosquitto_sub -h sonoff.maddox.co.uk -t '#' -C 1 But as a command line sensor it fails. I think in ssh it’s running in the host system but in a command line it’s running in the docker container or I might have them around the wrong way. In my case, one container or the other didn’t have the mosquitto_sub command available. Just confirmed in WinSCP, the host doesn’t work as mosquitto_sub does not exist in the /usr/bin folder. The hass.io …

Thanks David. I’ll give this a go.

delete_old_snapshots: find /usr/share/hassio/backup/* -mtime +30 -exec rm {} +

Might have to wait a couple of days for confirmation. I deleted the old files via ssh.

[tom_l]

No luck unfortunately.

run
which find
and give the full path for find. in my case it would be
/usr/bin/find /backup/* -mtime +30 -execdir rm {} +

[tom_l]

@turboc

run
which find

The trouble with that is SSH might work in a different container to HA, as evidenced by the previous commands working via SSH but not as shell_commands.

[turboc (Chip Cox)]

but the “find” command should be installed in the same directory regardless. There shouldn’t be two of them on the same server. What I’m thinking is that “find” isn’t being found in whatever environment you have when your shell command is run. You may have said this earlier, is this being run as a cron job or some other scheduler.

[tom_l]

A time triggered automation calls the shell command.

[tom_l]

core-ssh:~# which find
/usr/bin/find

[turboc (Chip Cox)]

so try putting /usr/bin in front of your find command and see if specifying the path to find helps.

[tom_l]

Sigh.

One last thing to try:

/usr/bin/find /backup/* -mtime +30 -exec rm {} +

That’s it. I’m out of ideas. Going to delete them from the samba share using task scheduler on another always on PC on the network.

[DavidFW1960 (David)]

@tom_l

Going to delete them from the samba share using task scheduler on another always on PC on the network.

Which is the approach I’m using. I think the issue as I said is the docker container running the command_line in yaml is different to the ssh container and those files just aren’t available in the command_line container.

[tom_l]

@DavidFW1960 do you just have a batch file with the command you posted above called by windows task scheduler?

[DavidFW1960 (David)]

Not a batch file. Using Task Scheduler defining an action like this:

[tom_l]

Just as well I tested this first. Going to have to map the samba share to a drive.

C:\Users\Tom>ForFiles /p "\\hassio\backup" /s /d -30 /c "cmd /c del @file"
ERROR: UNC paths (\\machine\share) are not supported.

[DavidFW1960 (David)]

yeah it took me a few dry runs and google to get it right.

[tom_l]

I still cant. I mapped H: to \hassio\backup and set this tast to run at 01:15 with highest privileges:

C:\Users\Tom>ForFiles /p "H:\" /s /d -30 /c "cmd /c del @file"

But the backup are still not being deleted.

[tbamha]

I created a batch file and run it nightly as a scheduled task. Below is the contents of the batch file. I use pushd and popd to avoid having to map a drive letter. To avoid having the DOS box appear when the scheduled job runs be sure and select “Run whether user is logged on or not” on the General tab when you setup the scheduled task.

@echo off
pushd \\hassio\backup
forfiles /M *.tar /D -15 /C "cmd /c del @file"
popd
