It's not possible to use pipes with cron-sentry

[hltbra]

Currently it's not possible to use have commands that use the shell capabilities. For example, it's not possible to wrap completely the following command with cron-sentry:

ls /dir | mycommand

With cron-sentry it would be possible to wrap the ls /dir part, but not the whole thing (unless cron-sentry is executed twice). So, if the ls command works, but mycommand fails, cron-sentry wouldn't catch it.

The above is true for |, ||, &&, >, >>, etc.

I didn't see this fork, and fixed that in the original project at https://github.com/mediacore/raven-cron/pull/7

In short, call() should be passed shell=True if there is exactly one token in the command line. In that case raven-cron "foo | bar" would honour the pipe. The bug in the original library was actually the opposite: they used shell=True with multiple tokens, e.g. raven-cron foo bar baz, with the result that the extra token were ignored.
