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> $ clamscan malware.zip malware.zip: Worm.Mydoom.U FOUND </PRE> When using the -allmatch(-z) flag, clamscan may print multiple virus <code>FOUND</code> lines for archives and files. <P> <BR><HR> <ADDRESS> Cisco 2018-02-01 </ADDRESS> </BODY> </HTML>
