One way is Instead of having two find commands, U can store the output of first find in a file.
Then u can do wc -l and rm.

like..
Code:
find $dirPath -type f -ctime $noDaysOld   >> output 2>/dev/null
noOfFiles=`wc -l output`
cat output | xargs rm

This will be faster compared to the two find command approach.

xargs is a command that accepts list of words and provides those as input to the given command.

Iam think that calling a shell script in the -exec is a better approach..

Thanks
Penchal

userdel

USERDEL(8)						      System Manager's Manual							USERDEL(8)

NAME

       userdel - Delete a user account and related files

SYNOPSIS

       userdel [-r] login

DESCRIPTION

       The  userdel  command modifies the system account files, deleting all entries that refer to login.  The named user must exist.  The options
       which apply to the userdel command are:

       -r     Files in the user's home directory will be removed along with the home directory itself and the user's mail spool.  Files located in
	      other file systems will have to be searched for and deleted manually.

FILES

       /etc/passwd - user account information
       /etc/shadow - secure user account information
       /etc/group - group information

CAVEATS

       userdel will not allow you to remove an account if the user is currently logged in.  You must kill any running processes which belong to an
       account that you are deleting.  You may not remove any NIS attributes on an NIS client.	This must be performed on the NIS server.
