clamscan</A>
</H3>
<code>clamscan</code> writes all regular program messages to <SPAN CLASS="textbf">stdout</SPAN> and
errors/warnings to <SPAN CLASS="textbf">stderr</SPAN>. You can use the option <code>--stdout</code>
to redirect all program messages to <SPAN CLASS="textbf">stdout</SPAN>. Warnings and error
messages from <code>libclamav</code> are always printed to <SPAN CLASS="textbf">stderr</SPAN>.
A typical output from <code>clamscan</code> looks like this:
<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. In case of archives the scanner depends on libclamav
and only prints the first virus found within an archive:
<PRE>
zolw@localhost:/tmp$ clamscan malware.zip
malware.zip: Worm.Mydoom.U FOUND
</PRE>
<SPAN CLASS="textit"><SPAN CLASS="textbf">TIP:</SPAN> You can force clamscan to list all infected
files in an archive using -no-archive (this option disables
transparent decompressors built into libclamav) and enabling external
decompressors: -unzip -unrar...</SPAN>.
<BR> <PRE>
zolw@localhost:/tmp$ clamscan --no-archive --unzip malware.zip
