Normalizing files for sentence count

I have files with many different formats and breaks in odd places. now I want to normalize them to be able to count the sentence in each file

1: I want to count the sentences is they finish with ! . ?
2: but I don't want it to count if there is no space after the Full stop. e.g. S.O.L

I have the following line but don't know how to make it work with second condition

FILES="basic/*"
for X in $FILES
do
	name=$(basename $X) 
	sed -n -e ":a" -e "$ s/\n/ /gp;N;b a" $X| tr '\. ' '\n '| tr '\? ' '\n '|tr '\! ' '\n '| grep -v "^[[:blank:]]*$" | wc -l > count/${name}
done

can someone please help me in this regards?:

I am translating your requirement to mean count all of the . ! and ? characters in a file.
This is part of what it means to find sentences. It will have problems, ex.: in text with numbers that have decimals in them. And sentences that end in an ellipsis.... < that is one! Neat. I made a self-referential sentence.

awk '{ total+=gsub(/[\.\?\!]/,"", $0); next}
END{print "total sentences=",total} ' somefile.txt

You have to decide on the correctness of your approach, based on your data.

Thank you very much for the code
I have to break the files into sentence per line as well and dont want it to divide the lines if there is a word or number of the "." so i have to know how to identify it.
can you explain this bit please?

$0 represents the whole record. Below is the syntax of gsub function:-

gsub(regexp, replacement, target)

The gsub function returns the number of substitutions made.

The normal way of doing this is to change spaces and tabs to newlines and then count the number of lines that end in ., !, and ?.

tr '[ \t]' '\n' file|grep -c '[.!?]$'

Hi.

I have been looking at the topic of processing English sentence lately. Here is a demonstration of a perl script to place sentences on separate lines (minimal version):

#!/usr/bin/env bash

# @(#) s1	Demonstrate minimal English sentence separation.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C perl divepm 

pl " Perl modules:"
divepm -q --input=minimal-sese

FILE=${1-data5}

pl " Input data file $FILE:"
cat $FILE

pl " Results:"
./minimal-sese -d $FILE

exit 0

producing:

% ./s1

The file uploaded needs to be copied to file minimal-sese and then made executable. The perl module Lingua/EN/Sentence.pm may be available in your repository. Otherwise it needs to be copied from the URL noted in the script comments.

Posting samples of your input and desired output will help invite on-point solutions.

Best wishes ... cheers, drl

Thank you very much... I will give this a go and ask if I have any question
