Full Discussion: Run A Job in Cron On A Specific Day Excluding Holidays
Top Forums UNIX for Advanced & Expert Users Run A Job in Cron On A Specific Day Excluding Holidays Post 302696057 by jim mcnamara on Tuesday 4th of September 2012 08:06:28 AM

Holidays are often company specific - like in the US a lot of companies grant the day after Thanksgiving.

Put a holiday schedule, updated every year, in a place where your code can read it. Determining holidays has to be up to the script. UNIX does not have such a thing.

Ex:
Code:
# holiday file
# Christmas
12-25-2012

crontab
Code:
* * 25 * *  /path/to/my/script.sh >/path/to/logfile 2>&1

In script.sh:
Code:
#!/bin/bash
today="`date +%m-%d-%Y`"
grep -qF "$today" /path/to/holidayfile && exit    # do not run on holidays
...rest of script here.

holidays(4)							   File Formats 						       holidays(4)

NAME

       holidays - prime/nonprime table for the accounting system

SYNOPSIS

       /etc/acct/holidays

DESCRIPTION

       The   /etc/acct/holidays file describes which hours are considered prime time and which days  are holidays.  Holidays and weekends are con-
       sidered non-prime time hours.  /etc/acct/holidays is used by the accounting system.

       All lines beginning with an "*" are comments.

       The  /etc/acct/holidays file consists of two sections.  The first non-comment line defines the current year and the start time of prime and
       non-prime time hours, in the form:

       current_year	 prime_start	  non_prime_start

       The remaining non-comment lines define the holidays in the  form:

       month/day     company_holiday

       Of these two fields, only the  month/day is actually used by  the accounting system programs.

       The  /etc/acct/holidays file must be updated each year.

EXAMPLES

       Example 1: Example of the /etc/acct/holidays file.

       The following is an example of the /etc/acct/holidays file:

       * Prime/Nonprime Table for the accounting system
       *
       * Curr	  Prime     Non-Prime
       * Year	  Start     Start
       *
	 1991	  0830	   1800
       *
       * only the first column (month/day) is significant.
       *
       * month/day    Company Holiday
       *
	 1/1	      New Years Day
	 5/30	      Memorial Day
	 7/4	      Indep. Day
	 9/5	      Labor Day
	 11/24	      Thanksgiving Day
