cron makes me grabby

i am running ubuntu 12.04
what i have done (in my useraccount) is:
crontab -e
insert the following line
2 * * * * /home/richi/tmp/my_id

the script is owned by me and is executable

the file in /var/spool/crontabs was created
ls -l /var/spool/cron/crontabs
-rw------- 1 richi crontab 1124 Nov 16 17:12 richi

but the result is that the script is running only every hour (looks like cron.hourly - but this directory is empty)

i also tried /etc/cron.allowd -> no change - cron is running only every hour.
whats going on ?

how often do you want it to run? and what is within the script?

hello
it is just a test for me and i want to run it only 3 or 4 times.
the contens of the script is:

/usr/bin/id -a >>/home/richi/tmp/my_id.txt
/bin/date >> /home/richi/tmp/my_id.txt

and the permissions are:
ls -l my_id
-rwxr-xr-x 1 richi richi 82 Nov 16 16:09 my_id

by the side i ain't change anything in the configuration

have you successfully ran the script from the command line?

i believe you need

Code:

---

#!/bin/bash

at the top of your script. also, what do you mean you want to run it 3 or 4 times? crontab needs specifics for how often you want to run it, whether it's once every 30 minutes or once every 10 minutes or what.

Your cron job is set to run once an hour on the second minute of the hour. What did you expect?

man cron

As has been said, your cron is set to run on the second minute of every hour. If you want it to run every 2 minutes or whatever, you would use a configuration like this

Code:

---

*/2 * * * * /home/richi/tmp/my_id

r
and here is the entry in my crontab:
2 * * * * /home/richi/tmp/my_id

and i expected that means every two minutes and i want to have it run every two minutes ( just for testing)
what is my mistake ?
