hello
im working on a bash script to calculate number of viruses found and log on log file.
ive paste some part of log file that are important for this script:
it has to search the file and find the number in front of the Viruses found phrase, and export sum of these numbers into temp file.
in this case, script pass number 15 into file.log
ive use regix to found but script exit after first result, it cant search all the files content

file::scan
Scan(3pm) User Contributed Perl Documentation Scan(3pm)NAME
File::Scan - Perl extension for Scanning files for Viruses
SYNOPSIS
use File::Scan;
$fs = File::Scan->new([, OPTION ...]);
$fs->set_callback(
sub {
my $filename = shift;
my $bytes = shift;
...
return("Callback Value");
}
);
$fs->scan([FILE]);
if(my $e = $fs->error) { print "$e
"; }
if(my $c = $fs->skipped) { print "file skipped ($c)
"; }
if($fs->suspicious) { print "suspicious file
"; }
if(my $res = $fs->callback) { print "$res
"; }
DESCRIPTION
This module is designed to allows users to scan files for known viruses. The purpose is to provide a perl module to make plataform
independent virus scanners.
METHODS
new([, OPTION ...])
This method create a new File::Scan object. The following keys are available:
callback => 'subroutine reference'
if the item is set then use a callback subroutine reference to provide extra information and functionalities. The callback
subroutine have two arguments: filename and first 1024 bytes read from the file. This only work for binary files.
extension => 'string'
add the specified extension to the infected file
move => 'directory'
move the infected file to the specified directory
copy => 'directory'
copy the infected file to the specified directory
mkdir => octal_number
if the value is set to octal number then make the specified directories (example: mkdir => 0755).
delete => 0 or 1
if the value is set to 1 delete the infected file
max_txt_size => 'size in kbytes'
scan only the text file if the file size is less then max_txt_size. The default value is 5120 kbytes. Set to 0 for no limit.
max_bin_size => 'size in kbytes'
scan only the binary file if the file size is less then max_bin_size. The default value is 10240 kbytes. Set to 0 for no limit.
scan([FILE])
This method scan a file for viruses and return the name of virus if a virus is found.
set_callback([SUBREF])
This method is another way to install a callback subroutine reference. Take a look in callback kay.
skipped()
This method return a code number if the file was skipped and 0 if not. The following skipped codes are available:
0 file not skipped
1 file is not vulnerable
2 file has zero size
3 the size of file is small
4 the text file size is greater that the 'max_txt_size' argument
5 the binary file size is greater that the 'max_bin_size' argument
suspicious()
This method return 1 if the file is suspicious and 0 if not.
callback()
This method return the result from the callback subroutine.
error()
This method return a error message if a error happens.
