I would like to run a program at 2:35 at the first Saturday of each odd month.
My solution:
35 2 1-7 1,3,5,7,9,11 6 /bin/program
The program was executed yesterday = Wednesday = day 3, cron ignores the day of the week!
not ignoring, OR-ing: $ man 5 crontab <snip> Note: The day of a command’s execution can be specified by two fields — day of month, and day of week. If both fields are restricted (ie, aren’t *), the command will be run when either field matches the current time. For example, "30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st and 15th of each month, plus every Friday. <snip>
don't know if there's a cleaner solution than using only eg saturday in cron and having a wrapper script for your program to check that it's the first week of a month.
