Compare the file names from a file to a directory
Hi,
I have to acheive the below logic in the script.
I have a file which has many columns and one of them is "File Names" and there will be only one such column name.
Eg., cat File1
Number of files:10
File Names: ABC, DEF, RTY,URE
....
...
...
The column will contain the different file names seperated by comma and each file names should be compared with the file names available in a unix directory for its presence. if the file is present with this name, script will be success or it should fail. eg., based on the above mentioned data, a file called ABC should be in a directory and similarly DEF, RTY and URE.
and there can be one file or can be more than one. eg., it can only be ABC or ABC and RTY or ABC, DEF, RTY,URE.
Can someone please help me with this?
Thanks
Vijay

number::compare
Number::Compare(3) User Contributed Perl Documentation Number::Compare(3)
NAME
Number::Compare - numeric comparisons
SYNOPSIS
Number::Compare->new(">1Ki")->test(1025); # is 1025 > 1024
my $c = Number::Compare->new(">1M");
$c->(1_200_000); # slightly terser invocation
DESCRIPTION
Number::Compare compiles a simple comparison to an anonymous subroutine, which you can call with a value to be tested again.
Now this would be very pointless, if Number::Compare didn't understand magnitudes.
The target value may use magnitudes of kilobytes ("k", "ki"), megabytes ("m", "mi"), or gigabytes ("g", "gi"). Those suffixed with an "i"
use the appropriate 2**n version in accordance with the IEC standard: http://physics.nist.gov/cuu/Units/binary.html
METHODS
->new( $test )
Returns a new object that compares the specified test.
->test( $value )
A longhanded version of $compare->( $value ). Predates blessed subroutine reference implementation.
->parse_to_perl( $test )
Returns a perl code fragment equivalent to the test.
