Hi I have to restart Apache from rails controller I tried to do that with %x{} and system commands but it fails so I decided to do it with cron Is it possible to make cron task that will be executed only once ?
The run once version of cron is called
at. See http://en.wikipedia.org/wiki/At_%28Unix%29 for an explanation, and note that specifying “now” as the time causes it to run immediately.
