First: Note that elements of a pipeline are separated by pipe symbols (|); not exclamation points (!). So the code you showed us in post #1 in this thread can't possibly produce the output you described.

Second: We have absolutely no idea what the format is for the data in bplist (or bplist.txt, depending on which part of your post we are to believe). We have absolutely no idea what the format is for the filenames (or pathnames) being processed.

Third: You have not explained why you need to count files to be removed instead of just identifying files to be removed and removing them.

Fourth: You have not given us any indication whether there are duplicates in one or both of your lists, whether files in one list are different than files in the other list, nor if there is any indication that there is a problem with the contents of either list (other than that the line counts are different).

Fifth: Why use the complicated:

Code:

for file in $(ls -lrt file_20160*.lis!awk '{print $9}')

which involves creating a subshell and invoking two utilities and can fail miserably if there are any whitespace characters in any of your filenames, when:

Code:

for file in file_20160*.lis

would be MUCH faster and, if you properly quoted the expansion (i.e., "$file") in your for loop, suffers none of the problems possible in your current loop.

asadmin-delete-instance

asadmin-delete-instance(1AS)					   User Commands				      asadmin-delete-instance(1AS)

NAME

       delete-instance	- deletes the instance that is not running.

SYNOPSIS

       delete-instance	 [--user  admin_user]  [--password admin_password] [--host localhost] [--port 4848] [--local=false] [--domain domain_name]
       [--passwordfile filename] [--secure|-s]instance_name

       Use the delete-instance command to delete the instance that you specify. The delete-instance command can be run both locally and  remotely.
       To  delete  the	instance locally, not requiring the administration server to be up and running, specify the --local option.  To delete the
       instance remotely, the administration server must be running on the hostname and port number specified. The user  authenticates	using  the
       password  identified  for the administration server. Additionally, the instance must already exist within the domain served by the adminis-
       tration server.	Use this command with discretion since it is destructive and there is no undo.

OPTIONS

       --user		       administrative user associated for the instance.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       administrative port number associated with the administrative host.

       --domain 	       name of the domain.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, SSL/TLS to communicate with the administrative instance.

OPERANDS

       instance_name		name of the instance to be deleted.

       Example 1: Using delete-instance in local mode

       asadmin> delete-instance --domain domain1 server1
       Deleted Instance server1 successfully

       Where: the server1 instance for the domain1 domain is deleted on the local machine.

       Example 2: Using delete-instance in remote mode

       asadmin> delete-instance --user admin --passwordfile passwords.txt --host localhost --port 4848 server1
       Deleted Instance server1 successfully

       Where: the server1 instance for the domain associated with the specified user, passwords in the password file, host,  and  port	number	is
       deleted on the remote machine.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command

INTERFACE EQUIVALENT
