2. scan each folder in the... (6 Replies)
The below bash runs clamav on all files in DIR and produces virus-scan.log. My question is the portion in bold is supposed to move the infected files, lines not OK, to /home/cmccabe/quarantine. Does the bash look correct? Thank you :).

oggcat
OGGCAT(1) User Manuals OGGCAT(1)NAME
oggCat - concatenates two ogg video files (.ogv, .ogg or oga)
SYNOPSIS
oggCat [options] outfile.ogv file1.ogv file2.ogv [ file3.ogv [...] ]
DESCRIPTION
oggCat concatenates two or more ogg files.
The parameters of the resulting ogg file is defined by the first file in the concatenation list. The parameters could be changed by some
options, explained below.
All subsequent files that does not match these video file parameters are automatically transcoded.
A concatenation will fail in case that there are not enought streams available. This could happen e.g. if the first file consists of one
audio and one video stream and the second file only carries a video stream.
If there is more than one video or audio stream within the file, the first stream is used.
OPTIONS -s Sets the size of the video frame. The size is given as <width>x<height>. At default, the video frame size is the size of the first
video stream.
Example: -s 320x240
-d Sets the datarate in byte per seconds for the video encoder (theora). This meant to be a upper threshold. So the file may be smaller
than assumed. If not set, the datarate of the first file is used.
Example: -d 1024000
-D Sets the datarate in byte per seconds for the audio encoder (vorbis). If not set, the datarate of the first file is used.
Example: -D 64000
-f Sets the frame rate of the video with numinator and demoninator and is the pictures per second. If only one number is given, the
denominator is set to 1. If not set, the framerate of the first file is used.
Example: -f 25:2
-F Sets the sample frequency (sample rate) of the audio data in Hertz. If the sample frequency does not match the one with the original
file, resamling is invoked.
Example: -F 32000
-c Adds comments to the video (theora) stream. Comments are given by a pair of type and value in the form 'type=value'. More than one
comment can be concatenated with a semicolon. It is recommended to use apostrophes as the command line may use the semicolon as a
seperator.
Example: -c 'AUTHOR=yorn;DATE=03.07.09'
-C Adds comments to the audio (vorbis) stream. Comments are given by a pair of type and value in the form 'type=value'. More than one
comment can be concatenated with a semicolon. It is recommended to use apostrophes as the command line may use the semicolon as a
seperator.
Example: -C 'AUTHOR=yorn;DATE=03.07.09'
-q Specifies the video quality for the newly created stream. Valid values can be chosen between 0 and 63 (best).
Example: -q 63
-rv Force to reencode the video stream. This is sometimes neccessary, if the video stream match in video parameters, but not in the the-
ora version. In that case, reencoding the video stream helps creating good results.
-x Force to overwrite the output file, even if it exists. This is mainly helpful if the oggCat is server controlled.
EXAMPLES
oggCat concatFile.ogv myfile1.ogv myfile2.ogv myfile3.ogv
or
oggCat -o concatFile.ogv myfile1.ogv myfile2.ogv myfile3.ogv
This command creates a cancatenated file concatFile.ogv that consists of the three files myfile1.ogv myfile2.ogv myfile3.ogv
oggCat -s320x240 -q63 concatFile.ogv myfile1.ogv myfile2.ogv myfile3.ogv
This command connects the three files myfile[1-3].ogv to file concatFile.ogv with the size of 320x240 and best quality.
