WARNING: Pedantic piconit (of which you are probably aware) ahead.
That will still have problems with leading/trailing spaces and backslashes. Misinterpretation of such filenames manifests as an inability to find a file that exists or as reading the wrong file.
To remedy those shortcomings:

Indeed you are correct. I did not want to overcomplicate things, but file names with spaces occur quite frequently so I felt that was the most important note to make...
To complete the quest for the most robust solution we should probably also use printf rather than echo, since not all echoes are immune to special characters:

Hi,
I need to concatenate data files with a .mp extension that are stored in directories by year. I want to keep the same filename as an output for example:

Hi.
I found many scripts in the web of achieving this.
But I like to use this one
find /EDWH-DMT03 -xdev -size +10000 -exec ls -la {} \;|sort -n -k 5 > LARGE.rst
But the problem is, why it still list out files with 89 bytes as the output? Is there anything wrong with the command?

file::dosglob
File::DosGlob(3pm) Perl Programmers Reference Guide File::DosGlob(3pm)NAME
File::DosGlob - DOS like globbing and then some
SYNOPSIS
require 5.004;
# override CORE::glob in current package
use File::DosGlob 'glob';
# override CORE::glob in ALL packages (use with extreme caution!)
use File::DosGlob 'GLOBAL_glob';
@perlfiles = glob "..\pe?l/*.p?";
print <..\pe?l/*.p?>;
# from the command line (overrides only in main::)
> perl -MFile::DosGlob=glob -e "print <../pe*/*p?>"
DESCRIPTION
A module that implements DOS-like globbing with a few enhancements. It is largely compatible with perlglob.exe (the M$ setargv.obj
version) in all but one respect--it understands wildcards in directory components.
For example, "<..\l*b\file/*glob.p?"> will work as expected (in that it will find something like '..libFile/DosGlob.pm' alright). Note
that all path components are case-insensitive, and that backslashes and forward slashes are both accepted, and preserved. You may have to
double the backslashes if you are putting them in literally, due to double-quotish parsing of the pattern by perl.
Spaces in the argument delimit distinct patterns, so "glob('*.exe *.dll')" globs all filenames that end in ".exe" or ".dll". If you want
to put in literal spaces in the glob pattern, you can escape them with either double quotes, or backslashes. e.g. "glob('c:/"Program
Files"/*/*.dll')", or "glob('c:/Program Files/*/*.dll')". The argument is tokenized using "Text::ParseWords::parse_line()", so see
Text::ParseWords for details of the quoting rules used.
Extending it to csh patterns is left as an exercise to the reader.
NOTES
o Mac OS (Classic) users should note a few differences. The specification of pathnames in glob patterns adheres to the usual Mac OS
conventions: The path separator is a colon ':', not a slash '/' or backslash ''. A full path always begins with a volume name. A
relative pathname on Mac OS must always begin with a ':', except when specifying a file or directory name in the current working
directory, where the leading colon is optional. If specifying a volume name only, a trailing ':' is required. Due to these rules, a
glob like <*:> will find all mounted volumes, while a glob like <*> or <:*> will find all files and directories in the current
directory.
Note that updirs in the glob pattern are resolved before the matching begins, i.e. a pattern like "*HD:t?p::a*" will be matched as
"*HD:a*". Note also, that a single trailing ':' in the pattern is ignored (unless it's a volume name pattern like "*HD:"), i.e. a glob
like <:*:> will find both directories and files (and not, as one might expect, only directories).
The metachars '*', '?' and the escape char '' are valid characters in volume, directory and file names on Mac OS. Hence, if you want
to match a '*', '?' or '' literally, you have to escape these characters. Due to perl's quoting rules, things may get a bit
complicated, when you want to match a string like '*' literally, or when you want to match '' literally, but treat the immediately
following character '*' as metachar. So, here's a rule of thumb (applies to both single- and double-quoted strings): escape each '*' or
'?' or '' with a backslash, if you want to treat them literally, and then double each backslash and your are done. E.g.
- Match '*' literally
escape both '' and '*' : '\*'
double the backslashes : '\\\*'
(Internally, the glob routine sees a '\*', which means that both '' and '*' are escaped.)
- Match '' literally, treat '*' as metachar
escape '' but not '*' : '\*'
double the backslashes : '\\*'
(Internally, the glob routine sees a '\*', which means that '' is escaped and '*' is not.)
Note that you also have to quote literal spaces in the glob pattern, as described above.

BUGS
Should probably be built into the core, and needs to stop pandering to DOS habits. Needs a dose of optimizium too.

HISTORY
o Support for globally overriding glob() (GSAR 3-JUN-98)
o Scalar context, independent iterator context fixes (GSAR 15-SEP-97)
o A few dir-vs-file optimizations result in glob importation being 10 times faster than using perlglob.exe, and using perlglob.bat is
only twice as slow as perlglob.exe (GSAR 28-MAY-97)
o Several cleanups prompted by lack of compatible perlglob.exe under Borland (GSAR 27-MAY-97)
o Initial version (GSAR 20-FEB-97)
