Hi All,

Thanks for the reply.
I'd tried as below, but encountered error.

0 8 ** 6 [ $(( $(( $(date +%s ) / 86400 )) % 2 )) -eq 0 ] && $HOME/admin/scripts/rjob.sh
crontab: error on previous line; unexpected character found in line.
crontab: errors detected in input, no crontab file generated.

---------- Post updated at 08:51 AM ---------- Previous update was at 08:41 AM ----------

I'm able to schedule with below syntax. Shall feedback the result..
0 10 * * 5 [ $(( $(date +'\%U') % 2)) -gt 0 ] && /usr/local/bin/your_script

[QUOTE=Chubler_XL;302848241]No Solaris platform available to test but this crontab entry :

Code:
0 10 * * 5 [ $(( $(date +'\%U') % 2)) -gt 0 ] && /usr/local/bin/your_script

Or run your script every friday and test week of year is odd with

Code:
if [ $(( $(date +%U) % 2 )) -gt 0 ]


Tested using below:
at now [ $(( $(date +'\%U') % 2)) -gt 0 ] && /path/rjob.sh
ksh: \35 % 2: syntax error

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
