Is there any validator for training purposes where you can enter cron syntax like

0 0/5 9-17 * *

and it will print out:

  • more detailed errors and suggestions
  • pronounced, readable text format (Option -h ;) )
    • e.g. "every 5 hours between 9th and 17th each month"

Unless you're using a different version of cron than I am, that line does not represent "every 5 minutes between 9 and 17 o'clock every day". I guess that's why a readable text format output is required. :-) –  Ladadadada Aug 15 '12 at 13:56
rofl, sorry, got confused while writing "crons" for jira: confluence.atlassian.com/x/gAISCw –  childno.de Aug 15 '12 at 14:38

You can use crontab -e which will open an editor allowing you to edit cron jobs. It will report errors in case you mistyped the cron job line.

shure, but I need something for really stupid guys who want to learn what they enter ;) (sometimes it's boring teaching this again and again to the trainees –  childno.de Aug 15 '12 at 12:31
@childno.de: It seems that you did not describe your question properly in the first time. –  Khaled Aug 15 '12 at 12:43
yes you're right, I'm sorry about that –  childno.de Aug 15 '12 at 12:51
