Hello, I'm trying to delete duplicates when there are more than 10 duplicates, based on the value of the first column.
e.g.
a 1
a 2
a 3
b 1
c 1
gives
b 1
c 1
but requires 11 duplicates before it deletes.
Thanks for the help

Good day all.
Using basic UNIX/Linux tools, how would you delete a line based on a character found in column 1?
For example, if the CITY name contains an 'a' or 'A', delete the line:

Chicago; Illinois
Houston; Texas

avisplit(1) General Commands Manual avisplit(1)NAME
avisplit - split AVI-files into chunks of a maximum size
SYNOPSIS
avisplit [ -i file -o base [ -s size ] [ -H num ] [ -t s1-s2[,s3-s4,..] -c -m -b num -f commentfile ] ] [ -v ]
COPYRIGHT
avisplit is Copyright (C) by Thomas Oestreich.
DESCRIPTION
avisplit splits a single AVI-file into chunks of size size.
Each of the created chunks will be an independent file, i.e. it can be played without needing any other of the chunk.
OPTIONS -i file
Specify the filename of the file to split into chunks.
-o base
Specify the base of the output filename(s) avisplit will then split to base-%04d.avi
-s size
Use this option to specify the maximum size (in units of MB) of the chunks avisplit should create. 0 means dechunk, create as many
files as possible.
-H num Create only the first num chunks then exit.
-t s1-s2[,s3-s4,..]
Split the input file based on time/framecode (hh:mm:ss.ms)
-c Together with -t. Merge all segments into one AVI-File again instead generating seperate files.
-m Together with -t. Force split at upper bondary instead of lower border.
-b num Specify if avisplit should write an VBR mp3 header into the AVI file. Default is 1 because it does not hurt. num is either 1 or 0.
-f commentfile
Read AVI tombstone data for header comments from commentfile. See /docs/avi_comments.txt for a sample.
-v Print only version information and exit.
EXAMPLES
The command
avisplit -s 700 -i my_file.avi
will split the file my_file.avi into chunks which's maximum size will not exceed 700 MB, i.e. they will fit onto a CD, each. The created
chunks will be named my_file.avi-0000, my_file.avi-0001, etc.
avisplit -i my_file.avi -c -o out.avi -t 00:10:00-00:11:00,00:13:00-00:14:00
will grab Minutes 10 to 11 and 13 to 14 from my_file.avi and merge it into out.avi
BAD SYNCH
When you split a file with avisplit and the A/V sync for the first file is OK but the sync on all successive files is bad then have a look
at the output of tcprobe(1) (shortend).
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 10 chunks, 1920000 bytes
You'll see the AVI file has only 10 Audio chunks but 250 video chunks. That means one audio chunk spans several video frames. avisplit can
not cut a chunk in half, it only handles complete chunks. If you do, say, avisplit -s 20, it is possible that the first file will have 6
audio chunks and the second one only 4 meaning there is too much audio in the first AVI file.
The solution is to remux the AVI file with
transcode -i in.avi -P1 -N 0x1 -y raw -o out.avi
(of course -N 0x1 is not correct for all AVI files). Now look at tcprobe again
| V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576
| A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps,
| 250 chunks, 1920000 bytes
The data in this file is exactly the same (its bit-identical) as it was in in.avi; the AVI file was just written in a different way, we do
now have 250 audio chunks which makes splitting much easier and more accurate for avisplit.
