passing options to a shell script

[Database Administrator]

Hi,

im trying to write a script that will accept two options out of a list
of 5 options. The first set of options comprise --test, --real and --
verbose, the second set of options comprises --months and --year and
it takes variables for each.

What i am trying to accomplish is, when any one of the first set of
variables is passed, a second from that set cannot be passed, and when
an attempt to pass more than one option from the first set an error is
given. the same applies to the second set of options.

I am using getopts to get the options, but failed to find a way to
restrict usage of only one option from the two sets of options.

any guidance appreciated.

Regards,

Mike

After parsing the options, just check wether you have seen options
from both mutually exclusive sets. Like

if test -n "$DATE" && test -n "$MODE"; then ....
