Question Date command does not work in a KSH when called from Cron
Hi,

I'm trying to execute a job on the last day of every month, for which i'm using the following code in my Korn shell script :

if [[ `date +%d -d tomorrow` != 01 ]];
then
echo allowed only on last day of month. Today is `date +%d` >t.stm
echo Tomorrow is `date +%d -d tomorrow` >s.stm
exit 0
fi
...
....
.... (actual code to be executed)


Here is the crontab entry for it :

2,32 6-10 28-31 * * /intl_cim/acq_mdl1/cms/prod/global/scripts/trigger.ksh prod > /dev/null 2>&1

Strange enough, when i execute this script from the command prompt it works fine, but when it is executed by the cron, the file s.stm and t.stm show the same date. Which means it is not calculating Date -d tomorrow.

Can you please help me understand why this would happen. Here is what uname -a on my machine says :

SunOS sppmd541 5.10 IDR_139180-01 sun4u sparc SUNW,Sun-Fire-15000

Thanks a lot.

diaglogd

diaglogd(1M)															      diaglogd(1M)

NAME

       diaglogd -  Support Tools Manager logging daemon

SYNOPSIS

       /usr/sbin/stm/uut/bin/sys/diaglogd

DESCRIPTION

       The  Support  Tools Manager (STM) uses a logging daemon ( diaglogd ) to read diagnostic events from the kernel via diag2 (diagnostic pseudo
       driver) and logs them in the system log files.

       diaglogd is launched automatically at boot by the STM daemon diagmond.  The STM User Interface, xstm , mstm , or cstm , Daemon commands can
       also be used to launch the daemon as well as shut it down and view the daemon's activity log.

       The log files created by diaglogd can be viewed using the STM utility logtool.

   Application Usage
       This daemon will be deprecated on new server models. Please use System Management Homepage (see hpsmh(1M)).

WARNINGS

       The  following message will appear on the system console when the diagnostic logging facility determines that the I/O subsystem has started
       logging excessive I/O errors.  This message will appear only once and I/O errors will be lost until the diagnostic  subsystem  can  recover
       from this condition.

	DIAGNOSTIC SYSTEM WARNING:
	  The diagnostic logging facility has started receiving excessive
	  errors from the I/O subsystem.  I/O error entries will be lost
	  until the cause of the excessive I/O logging is corrected.
	  If the diaglogd daemon is not active, use the Daemon Startup
	  command in stm to start it. If the diaglogd daemon is active, use
	  the logtool utility in stm to determine which I/O subsystem is
	  logging excessive errors.

       The  following  message will appear on the system console when the cause of the excessive I/O error logging is corrected.  The total number
       of I/O errors that were dropped will be placed in "XX".

	DIAGNOSTIC SYSTEM WARNING:
	  The diagnostic logging facility is no longer receiving excessive
	  errors from the I/O subsystem.  XX I/O error entries were lost.
