I am programming an ip camera that uses LINUX commands and need some help.The following line executes the ftp file every 30 min.
*/30 * * * * admin /etc/config/ftp
I am trying to execute the file every 30 minutes but only on a window from 8 to 7pm. I tried the following line but it didnt work.
30 8,9,10,11,12,13,14,15,16,17,18,19 * * * admin /etc/config/ftp
Any help is greatly appreciated. Thanks!
