Post subject: | DCRON Usage |
Hi, I have a bin bash file to execute each night to get my electronic EPG. Actualy a start it manually each 2-3 days. What is the correct way to add it to the DCRON daily task. Should i use the mythtv user or root? I'm not linux expert and i'd like to have a complete how to. By the way Linhes 8.2 is simply Fantastical !! Thanks Bob |

Open a xterm or ssh in and run Code: sudo cp /path/to/yourBashFile.sh /etc/cron.daily/

For example, http://www.pantz.org/software/cron/croninfo.html Here is a quick cheat sheet: Code: # * * * * command to be executed
#- - - - - #| | | | | #| | | | +----- day of week (0 - 6) (Sunday=0) #| | | +------- month (1 - 12) #| | +--------- day of month (1 - 31) #| +----------- hour (0 - 23) #+------------- min (0 - 59) # to run once daily you may use a shortcut @daily /path/to/yourBashFile.sh # or you can do it the old school way # run on the 0 min of the 23rd hour 0 23 * * * /path/to/yourBashFile.sh |

Do either of these ways survive an upgrade or will they be overwritten? |

They both would survive a command line (pacman -Syu) upgrade. Neither method would automatically survive an ISO upgrade but the /etc/cron.daily method would be in the backup for manual restoration. |

I used the simple: Code: sudo cp /path/to/yourBashFile.sh /etc/cron.daily/ There was a glitch in my code (relative path error ) I think it's fixed now. Will see tomorrow. It's a good idea to backup the Dcron private schedule and script. Thanks Bob |
