Thanks for all people who help me

Now my job is working and see you in another thread.

Hi my friend

I want to delete special scheduled task can any ony tell me how can I do that?

I have this command to delete all currently scheduled tasks [crontab -r]

You may have to Edit the crontab entry file,

and edit the cron entries write and quit.The changes will be reflected.

Try crontab -l , to see the latest changes that you have made.Hope this helps

Thanks

Yes My friend

after using crontab -e vi editor will be run but I can not make any thing

and I have tried crontab -r , all scheduled tasks was deleted

thanks

If crontab -e opened your current cron in an editor,what was the error while modifying the cron entries in the editor?

As we cannot remove specifically using crontab -r,You may have add the new crontab.

crontab -l > /tmp/mycron
Edit the /tmp/mycron
crontab /tmp/mycron

Thanks
