I need to run some scripts every night to move some files around in OMV. I want something that simple and easy to maintain and more or less stock standard.<\/p>\n

There are probably many variations on how this could be done but this is how I chose to do it.<\/p>\n

Before we start it is worth noting I have my RAID mounted by OMV at:<\/p>\n

\/media\/f20b47a4-d207-40aa-a7e6-42ea82354455<\/p>\n\n\n\n\n\n\n\n\n
1.<\/td>\nEnsure you have enabled home directories for users. I created a shared folder called “\/home” and\u00a0 enable this in “Access Rights Management | Users | Settings”:<\/p>\n

\"Users<\/td>\n<\/tr>\n

2.<\/td>\nCreate a user called “scheduledtasks” and make a member of the groups as all your other users. As a result this user should have a home directory along the lines of:<\/p>\n

\/media\/f20b47a4-d207-40aa-a7e6-42ea82354455\/home\/scheduledtasks<\/p>\n<\/td>\n<\/tr>\n

3.<\/td>\nCreate a shared folder called “scheduled_jobs”, I would also add this as a windows\/smb shared folder.<\/td>\n<\/tr>\n
4.<\/td>\nIn this folder create a simple shell script:<\/p>\n
#!\/bin\/sh\r\necho \"Running script \/scheduled_jobs\/test.sh\"<\/pre>\n<\/td>\n<\/tr>\n
5.<\/td>\nCreate a scheduled task with a command of:<\/p>\n
bash ~\/..\/..\/scheduled_jobs\/test.sh<\/pre>\n
\"Scheduled<\/td>\n<\/tr>\n
6.<\/td>\nOnce you have saved the task click on the “Run” button to show the dialog to “Execute cron job” – click on “Start”. It should return “Running script \/scheduled_jobs\/test.sh”, which is of course the echo command inside the script.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

When I setup a real task I found that for the types of task I wanted to do, including mounting SMB shares I needed to run it as root. This meant that I needed to specify the full path to my RAID drive. Thus my scripts started like:<\/p>\n

#!\/bin\/sh\r\n#\r\n# Script to archive appropriate folders\r\n# to the Archive folder.\r\n#\r\n# Tony Paterson\r\n# May 2007\r\n#\r\nRAIDRoot=\"\/media\/f20b47a4-d207-40aa-a7e6-42ea82354455<\/span>\"\r\n\r\n# Source function library.\r\nif [ -x \/etc\/rc.d\/init.d\/functions ]; then\r\n. \/etc\/rc.d\/init.d\/functions\r\nfi\r\n\r\n#\r\n# Get the date in the format \"Day of Week\" and time\r\n# This will mean that we will effectively keep a weeks backup\r\n#\r\nSHORTDATE=`date +%a`\r\n\r\n\r\n#\r\n# User config section\r\n#\r\nArchiveFolder=\"${RAIDRoot}\/backups\/daily\/essentials\"\r\nLogDir=\"${RAIDRoot}\/backups\/daily\/logs\"\r\nLOGFILE=\"${LogDir}\/backup_essentials.log\"\r\n\r\n#\r\n# archive folder exists\r\n#\r\necho \"Creating Backup Directory...\"\r\necho \"Creating Backup Directory...\" >> $LOGFILE\r\nsu - root -c\u00a0 \"rm -Rf ${ArchiveFolder}\"\r\nsu - root -c\u00a0 \"mkdir -p -v\u00a0 ${ArchiveFolder} \"<\/pre>\n
