Glenn,
Rather than put this out to the ast-developers list, can you please
put this on your "I get to it sometime list" as I think this falls in
your domain.
Enhance the printf "%T" option to able return first working day and last
working day of a month.
It is a very common requirement in shell scripts that automate weekly,
monthly tasks such as backups.
Here is how I do it presently for first working day of month but it would
be nice if it were builtin to ksh93.
#!/usr/bin/ksh93
#
# print first working day of each month in 2008 (assume Sat, Sun are non
working days)
#
year=2008
for month in jan feb mar apr may jun jul aug sep oct nov dec
do
day=1
dow=$( printf "%(%w)T" "${day} ${month} ${year}")
(( dow == 0 )) && day=2
(( dow == 5 )) && day=3
printf "%(%D)T\n" "${day} ${month} ${year}"
done
Regards and Thanks
Finnbarr P. Murphy
