Depending on your version of cron, you should be able to do (for hours, say):

根据你的cron版本,你应该可以做(几小时,比如说):

   1-23/2

Going by the EXTENSIONS section in the crontab(5) manpage:

通过crontab(5)联机帮助页中的EXTENSIONS部分:

   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:

对于更便携的解决方案,我怀疑您只需使用简单列表:

   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.

但是将命令包装在一个shell脚本中会更容易,如果在一个奇怪的分钟内没有调用它,它将立即退出。

Every odd minute would be:

每一分钟都会是:

1-59/2 * * * * 

Every even minute would be:

每隔一分钟就会:

0-58/2 * * * *

Try

1-23/2

From your question, I'm assuming Vixie Cron. I doubt this will work with any other cron.

从你的问题,我假设Vixie Cron。我怀疑这适用于任何其他cron。

As I read the manual "1-23/2" (for hours) would do the trick.

当我阅读手册“1-23 / 2”(几小时)就可以了。

Works on Cronie Even with 5 minutes interval e.g.

适用于Cronie即使间隔为5分钟,例如

3-58/5 * * * * /home/test/bin/do_some_thing_every_five_minute
