Crontab entry is not working
Hi I am trying to test the crontab entry by setting time as below ( set ahead more than 3min before saving the cron)

crontab entry:
Code:
30 15 1-27 * * [ "$(date '+%u%d')" == "227" ] && (cd /scripts;./script.csh.prod.UAT /dev/null 2>&1)

But this is not working, but below one is working.

Code:
30 15 1-27 * * (cd /scripts;./script.csh.prod.UAT /dev/null 2>&1)

Is there any error in this line?
Code:
>date '+%u%d'
227
> uname -a
Linux server 2.6.5-7.308.PTF.352368.0-smp #1 SMP Mon Dec 10 11:36:40 UTC 2007 i686 i686 i386 GNU/Linux

Please help me in this, it very urgent.

Hi.

The % sign has special meaning (check the manpage for crontab(8)).

Code:
     Only the first line (up to a `%' or end of line) of the com-
     mand  field  is  executed by the shell. Other lines are made
     available to the command as standard input. Any line  begin-
     ning  with  a `#' is a comment and will be ignored. The file
     should not contain blank lines.

Escape the %'s:

Code:
30 15 1-27 * * [ "$(date '+\%u\%d')" == "227" ] && (cd /scripts;./script.csh.prod.UAT > /dev/null 2>&1)

(you also missed a redirection)
