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.
