Precisely Don. The file has already been sorted by the columns you mentioned. Sorting isn't really the issue here though. The issue is finding the median for all strings in col1 that share an ID, writing that answer for all lines that have that ID, and performing the same thing for a new string. I notice now the output example I gave is not very clear. It should look like this
Hi ,
I have a requirement to split the record based on particular match using UNIX.
Case1:
Input Record :

Output Records :
10.44.48.63;Personals/Dating;1441;Original
10.44.48.63;sports;1441;Dummy

Trying to match $2 in original_targets with $2 of new_targets . If the two numbers match exactly then a match.txt file is outputted using the information in the new_targets in the beginning 4 fields $1, $2, $3, $4 and value of $4 in the original_targets .

Trying to match $1 of target.txt to $5 of file.txt. If there is a match then in an output.txt file $1,$1 (row underneath),$6,$4,$7 from file.txt are printed on the same line as $1 of target.txt. The input is from excel and the output should be tab-deliminated. Thank you :).

I am trying to merge two lines to one based on some matching condition.
The file is as follows:

I am trying to create a cronjob that will run on startup that will look at a list.txt file to see if there is a later version of a database using database.txt as the source. The matching lines are written to output.
$1 in database.txt will be in list.txt as a partial match. $2 of database.txt... (2 Replies)
Hi,
i have 2 files , the data i need to match is in masterfile and i need to pull out column 3 from master if column 1 and 2 match and output entire row to new file

is there an easier way than what i am... (4 Replies)

yuvdenoise(1) MJPEG tools manual yuvdenoise(1)NAME
yuvdenoise - Motion-Compensating-YUV4MPEG2-frame-denoiser
SYNOPSIS
yuvdenoise [options] </dev/stdin >/dev/stdout
DESCRIPTION
yuvdenoise is a spatio-temporal noise-filter for YUV4MPEG2 streams. This is useful to reduce the bitrate needed to encode your captured
movies for VCD and SVCD creation.
OPTIONS
yuvdenoise accepts the following options:
-g y,u,v [0..255] Gaussian filter thresholds
This sets the thresholds for the gaussian filter. A value of 0 disables filtering for a specific component and 0,0,0 completely dis-
ables/bypasses the filter. This filter is applied before the temporal (-t) filter.
(default=0,0,0)
-m y,u,v [0..255] Pre 3D Median filter thresholds
This sets the thresholds for the pre-processing 3D median filter. A value of 0 disables median filtering for a specific component and
0,0,0 completely disables/bypasses the filter. This filter is applied before the temporal (-t) filter.
(default=0,0,0)
-r y,u,v [0..255] Renoising filter thresholds
This sets the thresholds for adding random "noise" back into the video stream. Default is disabled (not adding random noise). This
filter, if enabled, is run as the Blast filter (after the median and temporal filters). Reasonable value is 4,8,8 but if you are work-
ing with monochrome (black and white movie) then 4,0,0 will speed things up by not processing the chroma planes.
(default=0,0,0)
-t y,u,v [0..255] Temporal noise-filter thresholds
This sets the thresholds for the temporal noise-filter. Values above 12 may introduce ghosting. The default value for Y' (y) is often
a little high and reducing it to 4 or 5 may be necessary. If the chroma smears or ghosts try using values of 5 or 6 instead of the
default (12). A value of 0 disables temporal filtering for the specified component (0,0,0 disables/bypasses all temporal filtering).
Thus for black and white movies 4,0,0 will be faster by not denoising the chroma planes.
(default=4,8,8)
-M y,u,v [0..255] Post 3D Median filter thresholds
This sets the thresholds for the post-processing 3D median filter. A value of 0 disables median filtering for a specific component and
0,0,0 completely disables/bypasses the filter. This filter is applied after the temporal (-t) filter. Reasonable value is 4,8,8 but
if you are working with monochrome (black and white movie) then 4,0,0 will speed things up by not processing the chroma planes.
(default=0,0,0)
HOW IT WORKS
To Be Written (maybe) in the future.
TYPICAL USAGE AND TIPS
As it is self-adapting to the noise-situation found in the stream you normally just can go without any options set:
