Run some command at a given interval. Mostly because CRON drives me nuts.
$ go get github.com/visionmedia/go-every
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
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/*"
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.
$ every 500ms echo hello
