I receive an error message when I try to start minicron.

[schueszy]

./minicron run ls error: undefined method `[]' for nil:NilClass. Use --trace to view backtrace

Can you let me know what version of minicron you are using (you can get this from minicron -v) and what OS?

[schueszy]

root@xxx:/etc# lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty root@xxx:/etc# ./minicron -v minicron 0.8.3

[jamesrwhite]

Yeah I can reproduce but only on linux not osx strangely, will have a look.

[jamesrwhite]

Ah, do you have an existing config file at /etc/minicron.toml? I made a breaking format change to that in a recent release, yours likely needs to be updated. I could reproduce the same issue on my own server that had an older version of the file. See minicron.toml for the most up to date example.

[schueszy]

Yes i have an existing file. I downloaded yesterday from github. I use mySQL instead of sqllite.

Apologies, there was an error in the example config that you based yours on. I fixed yours and it should be:

  dry_run = false

YEAHHH!!!! Thank you Mr White it works!!! ;-) root@xxx:/etc# ./minicron run ls [minicron] started running ls at 2015-11-21 14:39:45 UTC

But now i tried to create an job on the webinterface:

The server settings are correct. You can see here:

But after I've created a job , nothing happens

[jamesrwhite]

So I think the likely issue here is that minicron is not in your $PATH, when entries are put in the crontab it is assumed that this is the case. I'm still trying to work out the best way to solve this as with the new packaged versions of minicron its become a bit more complicated as minicron is no longer installed as a gem.

My short term recommendation would be to add the location of the unzipped minicron directory to your $PATH, you will need to do this in your /etc/crontab.

As an example mine currently looks like this:

SHELL=/bin/sh
PATH=/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

* * * * * james /bin/bash -l -c 'minicron run '\''echo 1'\'

..but you will need to add the minicron directory path to your $PATH, e.g

PATH=/path/to/minicron/directory:/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

Thank you very much now it works!
