I know this is a complicated question but I will try to illustrate it with some data. I have a data file that looks like the following:
I want to look at the first column and delete lines where the value on the first column is not repeated at least 6 times (in 6 different rows) throughout the text file. For example, there are 6 rows which start with 1341 or 1350 so I would keep those rows. But there are only 2 rows which start with 1362, so that row would be deleted. In the end my output would look like this:
Thanks a lot!

ppmtomitsu - convert a portable pixmap to a Mitsubishi S340-10 file
SYNOPSIS
ppmtomitsu [-sharpness val] [-enlarge val] [-media string] [-copy val] [-dpi300] [-tiny] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input and converts it into a format suitable to be printed by a Mitsubishi S340-10 printer, or any other Mit-
subishi color sublimation printer.
The Mitsubishi S340-10 Color Sublimation printer supports 24bit color. Images of the available sizes take so long to transfer that there
is a fast method, employing a lookuptable, that ppmtomitsu will use if there is a maximum of 256 colors in the pixmap. ppmtomitsu will try
to position your image to the center of the paper, and will rotate your image for you if xsize is larger than ysize. If your image is
larger than the media allows, ppmtomitsu will quit with an error message. (We decided that the media were too expensive to have careless
users produce misprints.) Once data transmission has started, the job can't be stopped in a sane way without resetting the printer. The
printer understands putting together images in the printers memory; ppmtomitsu doesn't utilize this as pnmcat etc provide the same func-
tionality and let you view the result on-screen, too. The S340-10 is the lowest common denominator printer; for higher resolution printers
there's the dpi300 option. The other printers also support higher values for enlarge eg, but I don't think that's essential enough to war-
rant a change in the program.
-sharpness 1-4
'sharpness' designation. Default is to use the current sharpness.
-enlarge 1-3
Enlarge by a factor; Default is 1 (no enlarge)
-media A, A4, AS, A4S
Designate the media you're using. Default is 1184 x 1350, which will fit on any media. A is 1216 x 1350, A4 is 1184 x 1452, AS is
1216 x 1650 and A4S is 1184 x 1754. A warning: If you specify a different media than the printer currently has, the printer will
wait until you put in the correct media or switch it off.
-copy 1-9
The number of copies to produce. Default is 1.
-dpi300
Double the number of allowed pixels for a S3600-30 Printer in S340-10 compatibility mode. (The S3600-30 has 300 dpi).
-tiny Memory-safing, but always slow. The printer will get the data line-by-line in 24bit. It's probably a good idea to use this if your
machine starts paging a lot without this option.
