Return codes</A>
</H2>
Return codes are very useful in system scripts. You can check the return
code from <SPAN CLASS="textit">clamscan</SPAN> by running:
<PRE>
$ clamscan; echo Return code: $?
</PRE>
Here is the full list of return codes for <SPAN CLASS="textit">clamscan</SPAN>:
<BR>
<P>
<SPAN CLASS="textbf">0: </SPAN> No virus was found.
<BR> <SPAN CLASS="textbf">1: </SPAN> Virus(es) detected.
<BR> <SPAN CLASS="textbf">40: </SPAN> Unknown option passed to <SPAN CLASS="textit">clamscan</SPAN>. Please check
clamscan -help or manual page for available options.
<BR> <SPAN CLASS="textbf">50: </SPAN> Virus database initialization error. Probably it doesn't exist
at the default location or it's malformed (e.g. broken digital
signature)
<BR> <SPAN CLASS="textbf">52: </SPAN> Not supported file type - clamscan only supports regular files,
directories and symlinks.
<BR> <SPAN CLASS="textbf">53: </SPAN> Can't open directory.
<BR> <SPAN CLASS="textbf">54: </SPAN> Can't open file.<SPAN CLASS="MATH"><IMG

HREF="footnode.html#foot1124"><SUP><SPAN CLASS="arabic">7</SPAN></SUP></A>
<BR> <SPAN CLASS="textbf">56: </SPAN> Can't stat input file or directory. File (or directory) you want to
scan doesn't exist.
<BR> <SPAN CLASS="textbf">57: </SPAN> Can't get absolute pathname of current working directory. Your
current pathname is longer then 200 characters. This is bad and
you may need to recompile ClamAV to fix it.
<BR> <SPAN CLASS="textbf">58: </SPAN> I/O error. Please check the filesystem.
<BR> <SPAN CLASS="textbf">59: </SPAN> Can't get information about current user (running clamscan).
<BR> <SPAN CLASS="textbf">60: </SPAN> Can't get information about user <SPAN CLASS="textit">clamav</SPAN>. User <SPAN CLASS="textit">clamav</SPAN>
(default unprivileged user) doesn't exist in /etc/passwd.
<BR> <SPAN CLASS="textbf">61: </SPAN> Can't fork. Can't create new process, please check your system limits.
<BR> <SPAN CLASS="textbf">63: </SPAN> Can't create temporary file or directory. Please check /tmp
permissions or use -tempdir
<BR> <SPAN CLASS="textbf">64: </SPAN> Can't write to temporary directory. Please specify another one.
<BR> <SPAN CLASS="textbf">70: </SPAN> Can't allocate and clear memory. This is a critical error, please
check your system.
