# $HOME scanner with "ClamAV" run from a virtual terminal with a bash alias.
# Check first if you've any other programs called scan, try "man scan" to see
# if manual pages exist, If ok add the alias to the bottom of your ~/.bashrc
# file, modify so it's path points to your scripts directory location.
# "alias scan="/home/user/users_scripts/scan.sh"" save, do "source ~/.bashrc"
# in a terminal to reload the bash configuration, type "scan" to scan.
# Scanning is done recursively on the directory you are in, terminal wise,
# ie. the $PWD - present working directory.
# If this script is likely to be run logged in as another user you'll need to
# be more specific with the path of the sound files.
