Create automated scan of specific directory using bash
I am trying to use bash to automate the scan of a specific directory using clamav. Having this in place is a network requirement. The below is an attempt to:
1. count the extensions (.txt, .jpeg) in a directory and write them to a virus-scan.log (section in bold)
2. scan each folder in the dir and log the results of the scan by date. (section in italics)
Each folder in the directory is scanned and the results of each day the scan is run is logged to /HOME/virus-scan.log by date.
Thank you .
Code:
#!/bin/bash
DIR=/home/cmccabe/Desktop/NGS/API
line_no=$(ls | awk -F . '{print $NF}' | sort | uniq -c | awk '{print $2,$1}') # count folder type and store as variable
echo >> $HOME/virus-scan.log"The folders detected are:
$line_no"
# Get rid of old log file
rm $HOME/virus-scan.log 2> /dev/null
while read FILE in $DIR;
do
# check file length is nonzero otherwise commands may be repeated
if [ -s $FILE ]; then
date > $HOME/virus-scan.log
clamscan -r $FILE >> $HOME/virus-scan.log
else "echo nothing detected by scan"
fi
done

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.
