AW3i/bin-cron

bin/cron

This command is mainly a wrapper for bin/magento for system cron context. It also supports external commands.

Features

Logging

The output of the cron command is logged in a file. Different files per passed identifier are created. A timestamp followed by the command output (or skipped - see next section) is logged.

Locking

flock (man page) is used to prevent, that a command with the same identifier is run in parallel. The second command will be skipped.

Commands

The main purpose is to execute bin/magento commands. With the --external flag other commands can be passed.

Installation

Requirements

For locking, flock (man page) needs to be available

Composer installation

composer require magenerds/bin-cron

For a more comfortable usage of this command, consider adding the executable flag to this command:

chmod 755 bin/cron
