<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
|
|
Archive: /tmp/malware.zip
|
|
inflating: test1.exe
|
|
inflating: test2.exe
|
