* Summary
Ruby libary and command line tool for testing cron jobs.
* Description
Execute an (almost) immediate and transient cron job using the same environment that is used to run your user's crontab.
* Requires
- [[http://github.com/soveran/clap][clap]]
* Usage
: 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
* Caution
I highly encourage you to keep a separate backup of your crontab before trying this tool as it is brand new and relatively untested.
