Help in preserving special characters from input file
Hi Forum.
I've tried to search online for a solution but I cannot seem to find one.
Hopefully, someone here can help me out. I would appreciate it.
Input file abc.txt:
[S_M_F_ING_MTG_COM_CUSTOMER_EXTRACT]
$InputFile_Borrower=CMTSLST\EDW_COMMERCIAL_MTGE_BORROWER_dat.lst
$InputFile_Customer=CMTSLST\EDW_COMMERCIAL_MTGE_CUSTOMER_dat.lst
$OuputFile_BorrowerNoGridID=CMTS\cm_borrower_exception_no_grid_id.out
$OutputFile_BorrowerDup=CMTS\cm_borrower_exception_dup.out
Output from script:
[S_M_F_ING_MTG_COM_CUSTOMER_EXTRACT]
$InputFile_Borrower=CMTSLST\EDW_COMMERCIAL_MTGE_BORROWER_dat.lst
$InputFile_Customer=CMTSLST\EDW_COMMERCIAL_MTGE_CUSTOMER_dat.lst
$OuputFile_BorrowerNoGridID=CMTS$OutputFile_BorrowerDup=CMTS
And here's the simple sample script to read/output the input file:
cat abc.txt | while read -r line
do
echo $line
done
The read "-r" option is suppose to treat the input data as raw, but I think the script is trying to interpret the line $OuputFile_BorrowerNoGridID=CMTS\cm_borrower_exception_no_grid_id.out
.... as \c special character.
I've read that single quotes can preserve the input data as is with no interpretation but I'm not sure how to implement it in my above script.
Thanks.

chi::driver::rawmemory
CHI::Driver::RawMemory(3pm) User Contributed Perl Documentation CHI::Driver::RawMemory(3pm)
NAME
CHI::Driver::RawMemory - In-process memory cache that stores direct references
VERSION
version 0.54
SYNOPSIS
use CHI;
my $hash = {};
my $cache = CHI->new( driver => 'RawMemory', datastore => $hash );
my $cache = CHI->new( driver => 'RawMemory', global => 1 );
DESCRIPTION
This is a subclass of CHI::Driver::Memory that stores references to data structures directly instead of serializing / deserializing. This
makes the cache faster at getting and setting complex data structures, but unlike most drivers, modifications to the original data
structure will affect the data structure stored in the cache, and vica versa. e.g.
my $cache = CHI->new( driver => 'Memory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # serializes $lst before storing
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['foo']
my $cache = CHI->new( driver => 'RawMemory', global => 1 );
my $lst = ['foo'];
$cache->set('key' => $lst); # stores $lst directly
$cache->get('key'); # returns ['foo']
$lst->[0] = 'bar';
$cache->get('key'); # returns ['bar']!
CONSTRUCTOR OPTIONS
Same as CHI::Driver::Memory.
SIZE AWARENESS
For the purpose of size-awareness, all items count as size 1 for this driver. (Because data structures are not serialized, there's no good
way to determine their size.)
# Keep a maximum of 10 items in cache
#
my $cache = CHI->new( driver => 'RawMemory', datastore => {}, max_size => 10 );
ACKNOWLEDGEMENTS
Thanks to Yuval Kogman whose Cache::Ref inspired me to do this.
