NAME
clamdscan - scan files and directories for viruses using Clam AntiVirus
Daemon
SYNOPSIS
clamdscan [options] [file/directory]
DESCRIPTION
clamdscan is a clamd client which may be used as a clamscan replace-
ment. It accepts all the options implemented in clamscan but most of
them will be ignored because its scanning abilities only depend on
clamd.
NOTE
If a file or an archive is larger than the default or configured size
(see MaxFileSize and MaxScanSize options in clamd.conf) scanning will
abort at the limit, and the file will be marked as "OK".
The archive scan limits are currently set to 25MB or 100MB respec-
tively.
There are more options that limit scanning, please check all the Max-
Something options in clamd.conf.
To report files that are exceeding these limits, you need to specify
AlertExceedsMax TRUE in clamd.conf. This will then report a "Heuris-
tics.Limits.Exceeded FOUND" for such files.
Please note that such a FOUND message does not imply infection, and
your tooling should be able to handle this.
OPTIONS
-h, --help
Display help information and exit.
-V, --version
Print version number and exit.
-v, --verbose
Be verbose.
--quiet
Be quiet - only output error messages.
--stdout
Write all messages (except for libclamav output) to the standard
output (stdout).
-c, --config-file=FILE
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.
-p A[:I], --ping A[:I]
Ping clamd up to [A] times at optional interval [I] until it re-
sponds.
-w, --wait
Wait up to 30 seconds for clamd to start. Optionally use along-
side ping to set attempts [A] and interval [I] to check clamd.
-m, --multiscan
In the multiscan mode clamd will attempt to scan the directory
contents in parallel using available threads. This option is es-
pecially 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. Simi-
larly, clamdscan will wait for clamd to finish a directory scan
(performed in multiscan mode) before sending request to scan an-
other directory. This option can be combined with --fdpass (see
below).
-z, --allmatch
After a match, continue scanning within the file for additional
matches.
--remove
Remove infected files. Be careful.
--move=DIRECTORY
Move infected files into DIRECTORY.
--copy=DIRECTORY
Copy infected files into DIRECTORY.
--no-summary
Do not display summary at the end of scanning.
--reload
Request clamd to reload virus database.
--allmatch
Continue scanning within file after finding a match.
-i, --infected
Only print infected files
--fdpass
Open the file and pass the opened file descriptor to clamd. This
is useful if clamd is running as a different user or if clamd
sees a different file system tree. This is faster than streaming
the file to clamd. Only available if connected to clamd via lo-
cal(unix) socket.
--stream
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.
EXAMPLES
(0) To scan a one file:
clamdscan file
(1) To scan a current working directory:
clamdscan
(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 -
RETURN CODES
0 : No virus found.
1 : Virus(es) found.
2 : An error occurred.
