Operating Systems AIX crontab entry Post 302292061 by bakunin on Thursday 26th of February 2009 07:55:15 PM

Create a crontab entry to run the script the first seven days of every month. This is straightforward. Within the script test for the day of week being Saturday or Sunday and stop if this test returns <true>.

This will work generally, the only exception being floating holydays.

To cover even this you will have to provide a list of holydays to the script and put it in crontab so that it is called daily. The script would first test if a new month has begun. If this is the case and the day of week is not a Saturday or Sunday or the date is found in the holyday list (in which case it aborts), it runs and increments a counter in a file until 5 is reached. If a new month has not begun the file with the counter is read and if the counter is already at 5 the script stops also.

In pseudo-code:

Code:
if( new month has begun since last run )
     clear counter-file

if( DOW is Saturday or Sunday or day is in holyday-list ) {
     abort
} else {
     if( counter file is less then 5 ) {
          do_work()
          increment counter file
     } else {
          abort
     }
}

I hope this helps.

		       |		|should replace the radix character

       If the locale's values for p_cs_precedes and n_cs_precedes do not match, the value of nl_langinfo(CRNCYSTR) is unspecified.

       The <langinfo.h> header declares the following as a function:

	 char *nl_langinfo(nl_item);

       Inclusion of <langinfo.h> header may also make visible all symbols from <nl_types.h>.

USAGE

       Wherever possible, users are advised to use functions compatible with those in the ISO C standard to access items of langinfo data. In par-
       ticular, the strftime(3C) function should be used to access date and time information defined in category LC_TIME. The localeconv(3C) func-
       tion should be used to access information corresponding to RADIXCHAR, THOUSEP, and CRNCYSTR.
