       clamdscan - scan files and directories for viruses using Clam AntiVirus


       clamdscan [options] [file/directory]


       clamdscan  is  a  clamd  client  which  may  be  used  as  a   clamscan
       replacement.  It  accepts  all  the options implemented in clamscan but
       most of them will be ignored because its scanning abilities only depend
       on clamd.


       -h, --help
              Display help information and exit.

       -V, --version
              Print version number and exit.

       -v, --verbose
              Be verbose.

              Be quiet - only output error messages.

              Write all messages (except for libclamav output) to the standard
              output (stdout).

              Read clamd settings from FILE.

       -l FILE, --log=FILE
              Save the scan report to FILE.

       -f FILE, --file-list=FILE
              Scan files listed line by line in FILE.

       -m, --multiscan
              In the multiscan mode clamd will attempt to scan  the  directory
              contents  in  parallel  using  available threads. This option is
              especially useful on multiprocessor and multi-core  systems.  If
              you  pass  more  than one file or directory in the command line,
              they are put in a queue and sent  to  clamd  individually.  This
              means,  that single files are always scanned by a single thread.
              Similarly, clamdscan will wait for clamd to finish  a  directory
              scan  (performed  in  multiscan  mode) before sending request to
              scan  another  directory.  This  option  can  be  combined  with
              --fdpass (see below).

              Remove infected files. Be careful.

              Move infected files into DIRECTORY.

              Do not display summary at the end of scanning.

              Request clamd to reload virus database.

              Pass the file descriptor permissions to clamd. This is useful if
              clamd is running as a  different  user  as  it  is  faster  than
              streaming  the  file  to  clamd.  Only available if connected to
              clamd via local(unix) socket.

              Forces file streaming to clamd. This is generally not needed  as
              clamdscan  detects  automatically if streaming is required. This
              option only exists for debugging and testing  purposes,  in  all
              other cases --fdpass is preferred.


       (0) To scan a one file:

              clamdscan file

       (1) To scan a current working directory:


       (2) To scan all files in /home:

              clamdscan /home

       (3) To scan a file when clamd is running as a different user:

              clamdscan --fdpass ~/downloads

       (4) To scan from standard input:

              clamdscan - <file_to_scan cat file_to_scan | clamdscan -


       0 : No virus found.

       1 : Virus(es) found.

       2 : An error occured.
