Changing timestamp file in crontab
Hi All

I want to change the date timestamp for the log file but to do it within crontab

I've tried the following..

40 11 * * * /data/dart/dc65.1/bin/adstats.sh > /data/dart/dc65.1/bin/adstats_`date'+%d:%m-%H.%M.%S'`.log 2>&1

But I only get adstats_

Any ideas?

Thanking you all inadvance...

Percent-signs (%) in the command, unless escaped with back-
slash (\), will be changed into newline characters, and all data after the
first % will be sent to the command as standard input.

confirmed, special characters need to be escaped. This became evident when I
Code:
cat /var/log/cron

in CentOS. The date command looked incomplete without the escapes. Thanks!
