Ruby libary and command line tool for testing cron jobs.
Execute an (almost) immediate and transient cron job using the same environment that is used to run your user’s crontab.
gem install crontest
to run crontest from the command line:
crontest 'echo hello! > MY_CRON_TEST.txt' &
or, to call from another ruby program
require 'crontest'
Crontest.run("echo hello! > MY_CRON_TEST.txt")
these will both run echo hello! > MY_CRON_TEST.txt as a cron job. it can take up to a minute to run as cron’s timing resolution is one minute.
crontest will create a backup file of your current crontab (cron-backup-[timestamp]) in the directory where directory you run it, and then restore it.
Options:
pass in options from the command line or Crontest.run(command, options)
--no-backup -n :backup => false
no backup file
-v :verbose => true
verbose output
I highly encourage you to keep a separate backup of your crontab before trying this tool as it is brand new and relatively untested.
