How to scan multiple directories with clamav

Question

I know how to scan one directory:

clamscan -r /home

but for the life of me I cannot seem to get multiple directories working and I cannot seem to Google this simple problem.

I have tried:

clamscan -r /home /otherdir
clamscan -r /home,/otherdir

to no avail.

What am I doing wrong?

Answer 1

You have to put the list of folders/files in a text file and pass it to clamscan using -f.

Example:
clamscan -r -z -i --bell --file-list=/home/nav/ClamScanTheseFolders.txt

Answer 2

DIRTOSCAN="/home /var/spool /bin /sbin";
for S in ${DIRTOSCAN}; do
  clamscan -ri "$S" >> "$LOGFILE";
done

Answer 3

Note that currently in Debian 10, I can scan two directories by simply passing them both at the command line:

clamscan -irv /root/test1/ /root/test2/

The switches stand for:

• v: verbose, to get the output
• i: infected only
• r: recursive

This will result in:

Scanning /root/test1/a.php
Scanning /root/test2/b.php
