Just execute the date command you are using and compare its output to what you are trying to match (does it have a "-" in it?).
Also, check which options you are trying to print in your date (use the command "man date").

Your command

a=`date +"%m-%d"`

has a "-" between the month and the date, but you are trying to match it to something that has a space there.


a=`date +"%m %d"`

should work.
