clamdscan --verbose



Hi Andrew,

--verbose does not solve the problem.

Consider this directory with two clean files:

# ls -l /tmp/files/
total 8
-rw-r--r-- 1 root root 452 Mär 13 12:15 clean.md
-rw-r--r-- 1 root root  27 Mär 13 11:53 clean.txt

# clamscan --no-summary --verbose /tmp/files/
Scanning /tmp/files/clean.md
/tmp/files/clean.md: OK
Scanning /tmp/files/clean.txt
/tmp/files/clean.txt: OK

# clamdscan --no-summary --verbose /tmp/files/
/tmp/files: OK

-> clamdscan does only report "all files in the given directory are clean"

Now, let's add EICAR.COM to the play
# ls -l /tmp/files/
total 12
-rw-r--r-- 1 root root 452 Mär 13 12:15 clean.md
-rw-r--r-- 1 root root  27 Mär 13 11:53 clean.txt
-rw-r--r-- 1 root root  69 Mär 13 11:54 EICAR.COM

# clamscan --no-summary --verbose /tmp/files/
Scanning /tmp/files/clean.md
/tmp/files/clean.md: OK
Scanning /tmp/files/EICAR.COM
/tmp/files/EICAR.COM: Eicar-Signature FOUND
Scanning /tmp/files/clean.txt
/tmp/files/clean.txt: OK

# clamdscan --no-summary --verbose /tmp/files/
/tmp/files/EICAR.COM: Eicar-Signature FOUND

-> clamdscan seem to have a fundamental different reporting model.

Maybe the developer could clarify?

Andreas
