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.

NAME
calendar - reminder service SYNOPSIS
calendar [-] DESCRIPTION
The calendar utility consults the file calendar in the current directory and writes lines that contain today's or tomorrow's date anywhere in the line to standard output. Most reasonable month-day dates such as Aug. 24, august 24, 8/24, and so forth, are recognized, but not 24 August or 24/8. On Fridays and weekends "tomorrow" extends through Monday. calendar can be invoked regularly by using the crontab(1) or at(1) commands. When the optional argument - is present, calendar does its job for every user who has a file calendar in his or her login directory and sends them any positive results by mail(1). Normally this is done daily by facilities in the UNIX operating system (seecron(1M)). If the environment variable DATEMSK is set, calendar will use its value as the full path name of a template file containing format strings. The strings consist of conversion specifications and text characters and are used to provide a richer set of allowable date formats in dif- ferent languages by appropriate settings of the environment variable LANG or LC_TIME; see environ(5). Seestrftime(3C) for the list of allowable conversion specifications. EXAMPLES
Example 1 Possible contents of a template The following example shows the possible contents of a template: %B %eth of the year %Y %B represents the full month name, %e the day of month and %Y the year (4 digits). If DATEMSK is set to this template, the following calendar file would be valid: March 7th of the year 1989 <Reminder> ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of calendar: LC_CTYPE, LC_TIME, LC_MES- SAGES, NLSPATH, and TZ. EXIT STATUS
0 Successful completion. >0 An error occurred. FILES
/etc/passwd system password file /tmp/cal* temporary files used by calendar /usr/lib/calprog program used to determine dates for today and tomorrow ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWesu | +-----------------------------+-----------------------------+ SEE ALSO
at(1), crontab(1), mail(1), cron(1M), ypbind(1M), strftime(3C), attributes(5), environ(5) NOTES
Appropriate lines beginning with white space will not be printed. Your calendar must be public information for you to get reminder service. calendar's extended idea of ``tomorrow'' does not account for holidays. The - argument works only on calendar files that are local to the machine; calendar is intended not to work on calendar files that are mounted remotely with NFS. Thus, `calendar -' should be run only on diskful machines where home directories exist; running it on a disk- less client has no effect. calendar is no longer in the default root crontab. Because of the network burden `calendar -' can induce, it is inadvisable in an environ- ment running ypbind(1M) with a large passwd.byname map. If, however, the usefulness of calendar outweighs the network impact, the super- user may run `crontab -e' to edit the root crontab. Otherwise, individual users may wish to use `crontab -e' to edit their own crontabs to have cron invoke calendar without the - argument, piping output to mail addressed to themselves.
