Your requirement isn't clear.
  1. Does the file hierarchy you're modifying contain symbolic links matched by the patterns /Path/AdminUser/* and /Path/AdminUser/*/*? Your textual description didn't say anything about symbolic links, but your (non-working) code explicitly ignores them. If symbolic links are found, what do want to have done with them?
  2. Are you trying to move all files in the file hierarchy rooted in /Path/AdminUser/ up one level in that hierarchy to /Path/; or are you just trying to move regular files with pathnames matching the pattern /Path/AdminUser/*/*/Reports/*.txt to the corresponding pathname after removing AdminUser/ from the source pathname?
  3. If a directory in the target pathname does not already exist, should your script report an error and move on, should it create the missing directories, or should it silently ignore that source pathname?
  4. Do you want to leave the (empty) source directories in place after files are moved out of them, or should emptied directories be removed?
  5. Is the entire file hierarchy rooted in /Path in a single filesystem?
Instead of saying "It still threw error, can we also write it in an efficient way?", show us exactly what "error(s) it produces" (in CODE tags).

What do you believe it is doing inefficiently?

NAME
/usr/bin/CpMac -- copy files preserving metadata and forks SYNOPSIS
/usr/bin/CpMac [-rp] [-mac] source target /usr/bin/CpMac [-rp] [-mac] source ... directory DESCRIPTION
In its first form, the /usr/bin/CpMac utility copies the contents of the file named by the source operand to the destination path named by the target operand. This form is assumed when the last operand does not name an already existing directory. In its second form, /usr/bin/CpMac copies each file named by a source operand to a destination directory named by the directory operand. The destination path for each operand is the pathname produced by the concatenation of the last operand, a slash, and the final pathname compo- nent of the named file. The following options are available: -r If source designates a directory, /usr/bin/CpMac copies the directory and the entire subtree connected at that point. This option also causes symbolic links to be copied, rather than indirected through, and for /usr/bin/CpMac to create special files rather than copying them as normal files. Created directories have the same mode as the corresponding source directory, unmodified by the process' umask. -p Causes /usr/bin/CpMac to preserve in the copy as many of the modification time, access time, file flags, file mode, user ID, and group ID as allowed by permissions. -mac Allows use of HFS-style paths for both source and target. Path elements must be separated by colons, and the path must begin with a volume name or a colon (to designate current directory). NOTES
The /usr/bin/CpMac command does not support the same options as the POSIX cp command, and is much less flexible in its operands. It cannot be used as a direct substitute for cp in scripts. As of Mac OS X 10.4, the cp command preserves metadata and resource forks of files on Extended HFS volumes, so it can be used in place of CpMac. The /usr/bin/CpMac command will be deprecated in future versions of Mac OS X. SEE ALSO
