Specifying "all odd values" in crontab?

Question

In crontab, I can use an asterisk to mean every value, or "*/2" to mean every even value. Is there a way to specify every odd value? (Would something like "1+*/2" work?)

Depending on your version of cron, you should be able to do (for hours, say): 1-23/2 Going by the EXTENSIONS section in the crontab(5) manpage: Ranges can include "steps", so "1-9/2" is the same as "1,3,5,7,9". For a more portable solution, I suspect you just have to use the simple list: 1,3,5,7,9,11,13,15,17,19,21,23 But it might be easier to wrap your command in a shell script that will immediately exit if it's not called in an odd minute.
