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
}
}

cal
CAL(1) User Commands CAL(1)NAME
cal - display a calendar
SYNOPSIS
cal [options] [[[day] month] year]
DESCRIPTION
cal displays a simple calendar. If no arguments are specified, the current month is displayed.
OPTIONS -1, --one
Display single month output. (This is the default.)
-3, --three
Display prev/current/next month output.
-s, --sunday
Display Sunday as the first day of the week.
-m, --monday

-V, --version

-h, --help

PARAMETERS
A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: cal 89 will not display a calendar
for 1989.
Two parameters denote the month (1 - 12) and year.
Three parameters denote the day (1-31), month and year, and the day will be highlighted if the calendar is displayed on a terminal. If no
parameters are specified, the current month's calendar is displayed.
A year starts on Jan 1. The first day of the week is determined by the locale.
The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the ref-
ormation (although a few did not recognize it until the early 1900's). Ten days following that date were eliminated by the reformation, so
the calendar for that month is a bit unusual.
HISTORY
A cal command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The cal command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
