cron a script and output to file named with date stamp
I can do this from the command line:
Code:
/home/mylogin/tests/script.sh > /home/mylogin/tests/`date +"%Y%m%d"`log.csv

It yields a file named: 20110429log.csv

I would like to schedule with cron to run daily.

when I enter the same line, as above in cron:
Code:
10 16 * * * /home/mylogin/tests/script.sh > /home/mylogin/tests/`date +"%Y%m%d"`log.csv

...it trucates at the first percent sign and yields a cron error:
unexpected EOF while looking for matching ``'
...cron executes:
/home/mylogin/tests/script.sh > /home/mylogin/tests/`date +"

It was suggested that I escape the percent sign:
Code:
10 16 * * * /home/mylogin/tests/script.sh > /home/mylogin/tests/`date +"\%Y\%m\%d"`log.csv

However, that doesn't seem to execute at all. I get no ouitput file and no sign of a cron error.

Any insight would be greatly appreciated.

Thanks,
-dog

amt

amt(1)								   User Commands							    amt(1)

NAME

       amt - run abstract machine test

SYNOPSIS

       amt [-s]

DESCRIPTION

       The  amt command is for use in a Common Criteria security certified system. The command is used to verify that the low level functions nec-
       essary to enforce the object reuse requirements of the Controlled Access Protection Profile are working correctly. /usr/bin/amt is a  shell
       script  that  executes  tests specific to your system. For a 32-bit system, the tests run as a 32-bit application. For a 64-bit system, the
       tests run twice; once as a 32-bit application and once as a 64-bit application.

       amt lists test results with a "pass" or "fail" for each test it performs, unless output is suppressed with the -s option.

OPTIONS

       The following option is supported:

       -s	Suppresses output.

EXIT STATUS

       The following error values are returned:

       0	All tests passed.

       >0	Count of the number of tests that failed.

       <0	Incorrect command line argument.
