It literally contains the characters 20150408_MGAC_[0-9][0-9][0-9][0-9].txt.
A little description about the root of the problem - There is a process that extracts the file names present in an SFTP server and updates a text file. I then have to search the files, with the above pattern (where the the data in the regex [0-9] can be any random number between 0 to 9), and make sure the file exists in the extracted list of files.
Once I confirm the file is present in the server, I loop through the list of files that I was expecting, which is nothing but the files with the wildcards (20150408_MGAC_[0-9][0-9][0-9][0-9].txt), I scp the file to my local, do a "gzip -c" to a new filename on the .txt format, and then I wish to rename the files, which I am unable to do..
I am sorry if I am confusing you, I have can give you an example if you want more information.
Thank you so much for offering to help!

perl::critic::policy::inputoutput::prohibittwoargopen
Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3pUser Contributed Perl DocumentatPerl::Critic::Policy::InputOutput::ProhibitTwoArgOpen(3pm)
NAME
Perl::Critic::Policy::InputOutput::ProhibitTwoArgOpen - Write "open $fh, q{<}, $filename;" instead of "open $fh, "<$filename";".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The three-argument form of "open" (introduced in Perl 5.6) prevents subtle bugs that occur when the filename starts with funny characters
like '>' or '<'. The IO::File module provides a nice object-oriented interface to filehandles, which I think is more elegant anyway.
open( $fh, '>output.txt' ); # not ok
open( $fh, q{>}, 'output.txt' ); # ok
use IO::File;
my $fh = IO::File->new( 'output.txt', q{>} ); # even better!
It's also more explicitly clear to define the input mode of the file, as in the difference between these two:
open( $fh, 'foo.txt' ); # BAD: Reader must think what default mode is
open( $fh, '<', 'foo.txt' ); # GOOD: Reader can see open mode
This policy will not complain if the file explicitly states that it is compatible with a version of perl prior to 5.6 via an include
statement, e.g. by having "require 5.005" in it.
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
There are two cases in which you are forced to use the two-argument form of open. When re-opening STDIN, STDOUT, or STDERR, and when doing
a safe pipe open, as described in perlipc.
