Hi,
would request your advise on this pls

I have a couple of directories with bunch of sub directories in date format

eg.
directory name :
/u01/app/date_list/2016-09-10
/u01/app/date_list/2016-09-11
/u01/app/date_list/2016-09-12
/u01/app/date_list/2016-09-13
/u01/app/date_list/2016-09-14
/u01/app/date_list/2016-09-15

would like to delete some directories by accepting date range in comma separated and delete only those directories.
e.g 2016-09-11,2016-09-13,2016-09-15

so outcome after delete would be
/u01/app/date_list/2016-09-10
/u01/app/date_list/2016-09-12
/u01/app/date_list/2016-09-14

I can hard code the base directory to be safe e.g

date_range=$1
base_dir=/u01/app/date_list
 for currentDt in $(echo ${date_range} | sed "s/,/ /g")
do
	if ([ "${currentDt}" != "" ] || [ "${currentDt}" != "*" ]); then
		# is this enough? or can we add some more validation ?
		# rm -Rf  ${base_dir}/${currentDt}
	fi
done


pls help is there any strong validation that I can perform. or a better way to handle this.

thanks in advance
