Hiii,
I have a requiremnt like this---

1) Utility will be run under MT owner.
2) This utility will clean files in ABC/envsw/logs. And following logs will be backed up or deleted.

Dispatcher Logs
Middle tier Logs
Sage log
Sage monitor log
Sage db clean up result log
Core files

3) mt_clean -a<action> [-t <time>]* -L <backup location>

-a<action> - has two values "delete" or "backup”. If not specified by default "delete" action will*occur. If*"backup" option is given, files will be backed up on the location specified by the -L, -L is mandatory if back up option is specified.

-t<time>* - The time is given with the -t option and its default is 1am
A time of 'now' means to execute the cleanup operation now
A time of 'never' means that the cleanup operation should not be scheduled and any existing cleanup should be cancelled.

-L <backup location> -*this field is mandatory if backup action is selected.

Note: As middle tier process are running and not stopped while this utility is running, the utility should create an empty*file with same name which has deleted or backed up. Otherwise middle tier logs will not be generated until the middle tier process is restarted. Any core files will be backed up or deleted according to the action chosen.*

It could be run as---

intasclean -a delete/backup now somelocation

Some of the portion of this script is preexisting.i have to wrote it like this only.I am not aware of getopts in scripts,i tried to google it also but nt able to understand,can you people please help me out in this.
getopts is required in this or anything that will be similar to this.I am getting errors when i ran this.done is not matching with while but later there can be more errors.
