go-every

Run some command at a given interval. Mostly because CRON drives me nuts.

Installation

$ go get github.com/visionmedia/go-every

Usage

  Usage: every [options] <interval> <command>

  Options:

    --no-stdout  suppress command stdout
    --no-stderr  suppress command stderr
    --quiet      implies --no-{stdout,stderr}
    --exit       exit on error

Examples

Running a backup:

$ every 1h do-redis-backup /data/dump.rdb

Commands are passed through sh(1) so you may utilize shell features such as globbing.

$ every 1m "sudo rm -fr /tmp/something/*"

Options

By default command stdio is piped through for display, and command failures are simply logged and ignored. If you wish to exit on failure use --exit.
