Output format</A>
</H2>
<SPAN CLASS="textit">clamd</SPAN> uses a clamscan compatible output format:
<PRE>
zolw@Wierszokleta:~$ telnet localhost 3310
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SCAN /home/zolw/infected
/home/zolw/infected/sobre.com: W32.Magistr.B FOUND
Connection closed by foreign host.
</PRE>
In the <SPAN CLASS="textbf">SCAN</SPAN> mode it closes the connection when first virus
is found. In the case of archives the output is exactly the same as
with normal files because archive support is transparent:
<PRE>
SCAN /home/zolw/Clam/test/test2.zip
/home/zolw/Clam/test/test2.zip: ClamAV-Test-Signature FOUND
</PRE>
<SPAN CLASS="textbf">CONTSCAN</SPAN> displays all infected files found.
<BR>
Error messages are printed in the following format:
<PRE>
SCAN /no/such/file
/no/such/file: Can't stat() the file ERROR
</PRE>
and they can be easily parsed.
<P>
<SPAN CLASS="textit">clamscan</SPAN> writes all messages to <SPAN CLASS="textbf">stderr</SPAN> (only help is
written to <SPAN CLASS="textbf">stdout</SPAN> by default). You may want to redirect it to
<SPAN CLASS="textbf">stdout</SPAN> - this is handled with <code>--stdout</code>. An example
of the clamscan output is:
<PRE>
/tmp/test/removal-tool.exe: Worm.Sober FOUND
/tmp/test/md5.o: OK
/tmp/test/blob.c: OK
/tmp/test/message.c: OK
/tmp/test/error.hta: VBS.Inor.D FOUND
</PRE>
When a virus is found its name is printed between the <code>filename:</code> and
<code>FOUND</code> strings. If a virus is found in an archive that has been
extracted with an external unpacker it's noticed with
<code>Infected Archive</code>. "Infected Archives" are not counted as infected
files - only files within them are. Notice the difference with built-in
unarchiver - extraction process is realized transparently by libclamav
and clamscan doesn't know which concrete file is infected - just marks
whole archives as infected.
