We need to write a bourne shell script to call a different command on different days of the week and dates of the month. Example;

IF date of month = 14 THEN

ELSE IF day of week = 1 (Monday) THEN

ELSE IF day of week = 3 (Wednesday) THEN

etc.

How can I get the current date of month and day of week?

Is the use of cron out of the question? With cron you could keep a Monday.sh, Tuesday.sh, 14th.sh, etc and schedule them using crontab.

You can still do the entire thing in a single script. To get dates, use `date +%?` - get the appropriate character for ? from the man page for strftime

Placeholders for values used in your example:
%w is weekday - 0-6 with Sunday as 0
%d is day of month with leading zero - 01-31


# date +%d
# 05

# date +%w
# 3

Cron will not work, because  the users will action the scripts and we don't want them to enter the parms
